The MC3000 would analyze the magic smoke battery just fine man. Check it out. Also, you should cycle the batteries multiple times, because the capacity most likely will increase after a few cycles in most cases.
Yeah well let's wait to see if he is actually going to release the follow-up video... Only about 3 months left. I am kind of bummed he did not include the Eneloop
I can't believe you didn't include Eneloop batteries. Best rechargable battery hands down. Eneloop has 2000 mAh. My oldest Eneloop batteries have lasted over 10 years so far. They still have over 60% life, which is leagues better than most rechargeables. So for longevity Eneloop might be the best, but I haven't read reviews of other batteries.
Tyler, that "AA Battery" is a lithium-ion battery. It has a regulator to drop the Li-on 3.7 volts to 1.5 volts. When you tried to charge it with a nickel metal charger, you probably damaged that circuit, and possibly the battery itself. That type of battery runs at 1.5 until it can no longer provide 1.5 volts, then it shuts off. That's why it acted the way it did when you tried to use it to run the fan.
I bought 16 Tenergy 2800 mAh AA batteries (and eight AAA Tenergys) and the Tenergy eight bay battery charger from Amazon. And as a ham radio operator that has insane experience with Nickel-Metal Hydrides for 30 years, they are the best ones I've ever had by far. You can leave them in a radio or whatever or leave them on a shelf and they hold their charge so much better than any I have ever owned.
Holy shit, that's quite a commitment. I'll be looking forward to the future test in a year. Keep in mind if you want to get through 1000 cycles in a year, you'd have to charge and discharge them 2-3 times a day.
I've got 20 year old every ready dual nicad, nimh battery charges and AA battery's 15 years old, that are charged daily for use in a portable dab radio, and right now they last about 45 minutes after a 4hr charge, they use to last approx 3 hours, same batteries.. So if regularly used can last a long time, I've also got nicads over 20 years old in an outdoor solar light, that comes on at dusk and charges during the day, these now last about 30 minutes when they use to last through the night..
did the 1000 chargingcycles with the EBL AA Batteries over the past 5 Years, Bought 8 of em, 5 are still doing great. I use them in my Camping lamp which I actually use as my Bedroomlamp 😅 It eats a set of Batteries every 3-4 days so yeah I get close to the 1000 cycles. The AA's do last but the AAA's from EBL died away like fruitflies within 2 years. Replaced them with Powerowl and "Tedi" branded rechargables and I have to say I am absolutely blown away from the Tedi branded ones, they still have their claimed capacity after 3-4 years
I noticed you didn't use Eneloop a Panasonic brand. I've used the same set of 8 batteries for about 10 years or maybe more and they're still decent batteries for wireless gaming controllers.
You should definitely re-run the capacity test and record the results every month or so throughout the year if you didn't already plan to. also, could be interesting to see which batteries get the warmest when fast charging and in use
Panasonic Eneloops are my go-to rechargeable batteries. The standard white ones and “pro” black ones have served me well for years. I wonder how they’d fare in this test.
The whites are rated a 2000 and pros at 2600. Even if they met those marks, the value isn't really there. The pros are $4.61 per cell right now in an 8 pack. They would have to really make up for it in longevity or low self discharge or something.
This, I feel like noone brings this up the Eneloops are so damn expensive for 4 Eneloops you get 12 of those Amazon's ones that are 2400 they are clearly a much better value even if 1 or 2 of them died, they have a close enough capacity and they're cheap
that is a crazy commitment to charge and drain those batteries every day! thank you for having the dedication to make all these projects into interesting fun videos :) I’ll be looking forward to the follow up video!
I can tell you what was happening to him at 1:50, he was trying to sneeze. He was trying to use looking at light to force a sneeze cause his nose was tingling. He may have photic sneeze reflex like I do, which means heavy eye stimulation triggers sneezing. It's actually quite useful when you feel the need to sneeze.
5:40 the usb recharge battery is a lithium battery with a buck converter to drop it to constant 1.5v. when the internal lithium 3.7v battery "dies" gets below it's minimum voltage cutoff the buck converter just shuts off the output.
To promote battery lifespan and reduce the risk of handheld napalm fans, rechargeable batteries have battery management systems (BMS). These are what control the charge/discharge rates and levels of the units. That is why the fans just shut off at a certain level instead of fading out. It is also why the operational maths aren't necessarily a direct reflection of mAh. Great job! I appreciate you informing me that I bought crap batteries. :)
@@Xrayfk05 except eneloop do a normal version and a high capacity version (pro) for that very reason. The normal ones rated for 2000 cycles, the pros at 500 cycles.
@@EspadaMK I have both of those batteries, I use eneloop's for my VR controllers. They are at 1.4v when they come off my charger and maintain the voltage for longer, they don't suffer droop like other batteries. It's the same with 18650's as well, I have high and low capacity and the largest, and most expensive, show significant degradation after 500-800 cycles as well.
When I clicked on this video I was expecting a topic on which rechargeable battery is the best, however I walked away with vast knowledge on the finite universe in which we reside. Truly peak performance, what others see as a grain of sand in a desert on this UA-cam platform, I see all the atoms and molecules which reside in said grain. Thank you for blessing us with this. Also tiddy.
It's also a Lithium battery.. Not Nimh battery.. That's why the first one fried in the charger! I take it Tyler doesn't read the description on Amazon..
@@Tig3rj Thinking of "the average person", if it looks like a battery it probably charges like a battery. Unknowingly those people create an incendiary device...Who reads chinglese descriptions?
Excellent test. I just bought a 24 pack of Amazon rechargeable aa’s and a 24 pack of rechargeable aaa’s. Came here to justify my purchase and now I feel even better about it, thanks

Draining and recharging the batteries once a day is a hell of a commitment to make! Glad to see you're so dedicated to this!
Yes, I noticed that, too. I'm very happy with the Eneloop batteries I've used for the last 10 years. They are 1,900 mAh, and they only take 3 hours to recharge. I was surprised when Tyler mentioned that he was going to recharge his batteries for 12 hours! That seemed rather excessive to me.
I didn't read all of the comments but the regular Duracell battery is 1.5V and most rechargeable batteries are only 1.2V. Something to think about there. Thanks for doing this test!
Hey Tyler, awesome test! In addition to the life cycle test that you intend to do, could you do a long term test where you charge them, leave them for several months or a year inside a flashlight without turning it on and then testing what capacity they have left after such time and how long they last? Maybe you could leave one unit of each battery inside a flashlight and another unit of each battery in their plastic case without making contact with anything to see if there’s a difference. I feel like with every rechargeable battery I’ve used, even though I always leave them fully charged, they usually die fairly early/not even hold any charge when I try to use them a few months after charging them.
I've been off grid for many, many years and used a lot of different types of rechargeable batteries and I used to use rayovac and Energizer batteries but when I started using the thunderbolt rechargeable batteries they seam to last longer than the more expensive ones and also lasted longer in years of charging them.
Results also depend on fans motor quality, batteries' voltage (discharge curve - more voltage=more speed) and chemistry (this time there were only NiMH and a single li-ion): * NiMH usually start at 1.4V then stay at 1.3-1.2V most of the time (fans with them will rotate slower and flashlights will be dimmer). And also since they're working at 1.2-1.3V most of the time - some smart electronics will think that betteries are almost discharged even on full batteries. * Li-ion batteries (with built in 1.5V regulators and usb chargers) are running at locked 1.5V until they're completely discharged. I find them dangerous to use and even store - electronics inside them is very dumb and li-ion is dangerous when something goes wrong. But when they work they're VERY convenient - as they dont require special chargers and 100% compatible due to 1.5V output. Capacity is kinda meh because of all of the additional electronics in them. * NiCd - terrible old technology, 1.2V, worse in all possible ways than NiMH. * NiZn - spicy boys. Fully charged they start from 1.85V, then quickly drop to 1.6-1.7V and only right before full discharge it starts dropping to 1.4-1.5V. That means that fans will spin faster and flashlights shine brighter (but more stress on such dumb components, in rare cases can fry electronics). Smart-ish electronics will believe that battery is almost fully charged even when its almost dead. Some electonics that doesnt like lower NiMH volatges works better with NiZn than on Alkalines (normal batteries). Compared to NiMH their capacity varies depending on use case (can be worse or better).
Here is one thing to think about. A different fan was used for each battery, which each could draw different amps. Nothing to noticeable, but maybe enough to effect the results. I wonder what would happen if Duracell and Amazon batteries switched fans, if you would get the same result.
The quality control on the fans is important, a slight difference in friction would change the results. Comparing two batteries at a time would mean the fans could also be tested. The two fans with the closest characteristics could be identified. Maybe take two makes of batteries at a time and have quarter finals etc I like the idea of testing several at a time, but there are a number of parameters. Holding a charge over time, say a week, a month, three months .. Lots of videos possible !
While you continue testing, could you do a shelf life test on the rechargeable batteries too? We would like to know after you’ve charged them to full capacity and they’ve set on the shelf for say a month, which one loses the most power?
Couldn't help but chuckle when I saw the cooked pasta stuck to the wall. I think Tyler is the only real tuber on here. Everyone seems fake or overactive. Tyler is one of us that made it.
Amazon Basics tend to be rebranded Eneloop. The higher capacity NiMh batteries are usually a little thicker than standard capacity and don't fit in all devices that alkaline will fit into.
I'm so happy that he's gonna do a year of charge/discharges, I figured he was just gonna ignore the longevity aspect. I would've been happy if he'd just ran the first test like 20 times in a row but dayum.
Eneloop batts are great. They may not have the best capacity, but they always have great self discharge specs and maximum charge cycles. Amazon basics that I used in 2017 had a limited service life. I used AA Eneloops extensively in my job. Eneloops sold in N. America are made in Japan.
Air draft on both sides of fans that are standing in the middle of the row helps them to preserve energy. Fans that are on edgeds have that kind of helpful stream of airflow present only on one side. Maybe that contributed to the struggles of fan #1 and to the success of the Amazon battery.
I really needed some TylerTube. I was just watching Muta's cat video and was feeling way sad. But who could be sad watching Tyler test random Amazon stuff?
like I said in a previous video. Those Amazon Batteries are actually really good. They're just rebranded Eneloops. You're also 100% right about the PowerOwl's. They're pretty much the best you can get... if you dont get a dud. They do seem to have extremely bad QC.
I've been using various rechargeable AA batteries for a 8 or 10 years now and while I bought some Duracell and Energizer here and there I've gone mainly with Power Owl after finding the Amazon ones occasionally slightly out of spec (short) in size causing the odd one here and there to not fit in all my AA needing devices which I put down to quality control at the source. I've seen reports of similar quality control issues with Power Owl in size but haven't had any trouble with the several orders I've placed in the last couple years.
For NiMH, the rechargeables that get a lot of press are the ENELOOP brand. I have more recently been getting good value from some LiION rechargeable AAs.
This test is probably one of your absolute best this year. Seems completely serious and a test you can actually benefit from, even in Sweden, where I am. Thanks!
Was the garage cold when testing? I literally just watched another video testing rechargeable AAs and the NiMH from Amazon Basics did the best. For a cheap, rechargeable battery, they seem to be of decent quality.
The USB C prot battery is a lithium battery dressed up as a AA battery, they sound good but because of the added voltage stuff in it the capacity sucks pretty hard and they waste a LOT of power in the conversion from 3.7V to 1.5V. they also only tend to last a handful of recharge discharge cycles before they clap out.
YOU CAN BUY 14500 BATTERIES WHICH ARE BASICALLY AA BATTERIES , but run at 3.2 to 3.7 volts like an 18650. that way you dont lose battery capacity on extra electronics to downgrade the voltage to 1.5. Then they sell dummy batteries , so if your flashlight usually uses 2 aa's, use 1 x 14500 and a dummy and you'll get a slightly brighter beam and long lasting. just charge them in a li-ion charger
I would recommend going off percentages instead of the milamps. For the charge and discharge. I'd also suggest getting those solar puck lights and throw them outside. It'll drain and recharge and show how the weather treats the batteries.
not trying to defend trash where the label applies, but the usb charge one was 1.5v, while the others were 1.2v batteries. in some devices it matters, in the vast majority of devices it doesn't though. just pointing that out as a downfall of rechargeable batteries are typically 1.2v. great video as always tyler :D
How durable is the insulation? Is it so tight and soft that rubbing against the device going to peel it off and cause a short? Big problem with rechargeable flashlight batteries
EBL barely holds a charge over time either. A note here, you can just about tell the capacity of a cell by weight in grams. The heavier the more output. The USB chargeable ones are actually 3.7 lithium Ion cells, regulated down to 1.5 volts.
I would buy Amazon basics. However there is one more test, which is consistency. Will another battery from the same pack perform the same or are there inconsistencies?
Hey thanks for the video! Good stuff here. I just have a couple notes on your test method. In terms of the fans you used, they are all the same which is good but there could be different motor resistance inside each, causing different batteries to have different loading. Also, the pitch of the foam blades may not be the same on each because of the flexible foam. That would also cause different loading on each battery. Lastly, the two fans at the ends, experience different aerodynamic loading due to the Coanda effect. Essentially the two fans at the ends experience a higher load, which may be why the Duracel didnt last as long, despite having a larger capacity. One last note, each battery chemistry has a certain discharge capability. That might be why some of them have lower capacity while being the same size. I think I read somewhere that capacity is inversely related to discharge rating.
I have been waiting for this video since the non rechargeable battery video. I went out and bought Thunderbolt Edge batteries after that and they work like a dream. It was the first time I'd ever gone into a Harbor Freight store too.
The rechargeable (nimh) perform better at higher power than standard (alkaline). I assume the fans are pretty low draw, it would be interesting to see some cheap high power flighlights or something to test along with the fans. Eneloops are the best, and any made in Japan AA is probably a re-wrap of the same quality.
lithum rechargeable AA are 1.5v normal AA voltage. but they provide the same current till death. wear the others are 1.2v as they dye there current slows till death
So, someone probably mentioned this at the beginning, but in case they didn't... the usb charging battery is lithium. From what I've gathered while trying to see if rechargeable was worth investing in, the battery is natively 3.7v and has to have resistors/capacitor to bring the voltage down to the usable 1.5-1.6v range (and there is some loss when going through this) But when the capacity was listed it was in mWh instead of mAh, which since it is a different native voltage, is not as useful to compare. Instead most NiMh batteries are closer to 1.2v (though I'd like you to check 🤔) To compare them fully you'd be best served by multiplying their stated mAh by their actual voltage. (it might even explain the slight difference between duracell and amazon) but then all bateries capacities would be listed in mWh for apples-to-apples comparison. Lastly, lithium are much better at providing full power till fully discharged, but also dealing with circuitry to step down the voltage, it might artificially cut it off even though it still has electrons "in the tank" This whole discussion has me intrigued, seriously it seems like the lithium would be great if they prioritized creating a cemistry from the ground up that matched 1.5v instead of jerry-rigging something to work or using NiMh at a lower voltage... both seem like they're trying to make sure they don't canablize the existing alkaline industry... So as long as the "big battery" mafia doesn't come knocking on my door, I look forward to seeing if any of these batteries can come close to their cycle ratings!
You need to do each test multiple times. There will be variances. Then figure the statistics of the tests. The endurance test with the fans is neglecting the variances in the fans themselves. I'd switch the batteries in the last two fans and run the test again (multiple times). Yeah, I know, it would be very time consuming.
I actually use the ebl, and they are incredibly durable. Been charging and recharging then for over a year. Well worth the money. And they have decent capacity, but it's not a big deal anyways, since you can just get a bunch of batteries, and charge them all up, and your good to go. The reason why i mental durability, is because they won't last forever, eventually they will stop working. So you have to check how many charges they are good for. So i know the ebl will work great
aww u didn't test my favorite Panasonic Eneloop i been using the same batteries for over 5 years for my oculus touch vr controllers and they only seem to die around a week or 2 earlier than they originally did when new, would be interesting to see tests on these
Each individual battery's capacity could vary a bit. In a test like you did with the fans, 50mAh-s or so counts quite a bit. If you didn't use the exact same batteries wich you tested previously for capacity, maybe that's why the Duracell died before the amazon basics. It could be from a slighty worse batch, or the Amazon basics could be from a slightly better.
Duracell VS Amazon, difference is in the internal quality/efficency. Example a clock use way less energy than a fan motor so maybe on a clock Duracell could have lasted more in theory. Because the more energy you demand the less is the usable capacity of the battery. Is called "C" factor. On data sheets is always indicated the "C" factor used to determine the capacity (ex. 2500mAh). If you discarge the battery at a "C" higher than the "C" used during the capacity test, the capacity will be less. For this reason the Duracell lasted less than the Amazon...because the Amazon is better made and more efficient than the Duracell. Also with fast charging (like fast discharging with fan) Amazon is way more efficient than Duracell and can absorb the high amount of energy better. Amazon batteries are superb for the price, better than any other you can find. And in your video you are using the "Amazon High capacity" that are the worst of Amazon. The "Basic" have around 20% less capacity but are always ready to use (after 2 years unused will keep almost 80% of the energy, so self discharge is quite null, like eneloop and can be recharged 1000 times compared to the 500 times of the High capacity). Now Amazon transfer production in China but Amazon NiMh battery bought some years ago reported a good "Made in Japan" label. So only Eneloop and Sanyo are made in Japan and in my opinion the Amazon NiMh was relabelled Sanyo, now transferred in China for contain price. At the moment Powerowl cost more than Amazon basic batteries so there are no reason to buy something different than Amazon Basic batteries. Amazon High capacity batteries cost few cents more than powerowl. The USB-C AA batteries are trash. They have internal Litium battery (like powerbanks) with internal charge controller. Since Litium battery will damage/explode if discharged or charged too much, the internal charge controller simply turn off the DC/DC converter that put out constant 1,5volt needed for a typical AA battery when internal litium battery is too low (typically around 3,2 volt), and stop the charge when internal lithium battery reach around 4,2 volt. This make these kind of AA lithium battery very dangerous (100% are from unknown chinese manufacturer without any warranty for safety) + the internal charge regulator and DC/DC converter use 30% of the space so will not leave too much space for the litium battery that is really small. In fact lasted less than all and will turn off instantly without any advice when internal lithium battery is low. Secondary the internal DC/DC converter needed to convert the lithium variable tension between 3,2/4,2 volt to 1,5 volt and will produce hot due to joule effect so for not burn itself the DC/DC will have for sure a power limiter (like that putted inside powerbanks and smartphone charger) so in a thight not vented place like inside an AA battery I think the AA USB-C battery can not handle more than 500mA of current compared to the several thousands of mA that a normal AA battery can delivery (starting current). So for understand better, as example, is you put 8 USB-c AA batteries inside an RC car, you will play really few time and maximum speed of the car will be really poor (for the internal battery current limiter). With normal AA nimh battery RC car will run way faster since a toy like that can run 15 miles per hour and for sure will draw from battery more than 3000mA (starting current) when accelerating. With USB-C AA this current is strongly limited.
You should have had Eneloop and Eneloop Pro in the mix. They're supposed to be some of the best rechargeable batteries that money can buy. I've never properly tested them, but in my own experience, the regular Eneloops have worked way better for me than rechargeable Duracell or Energizers.
I love your videos for many reasons but one of the main reasons is you are doing these tests because you genuinely have no idea what the results will be and want to find out yourself. Me (and all the viewers) love seeing your reactions. This channel is so great simply because it is your average Joe(Tyler in this case) testing things. Keep doing what you're and please never change. Hands down favourite channel
See if love to say this works and is credible but you ran only one battery. You kinda have to measure a sample size to compare given values such as capacitance or run time. Still I think it good analysis for only compare one type of battery each.
i guessing the usb c one is lithium so it will just hit a wall quickly. im assuming the others slowed down. the lithium would stay flat out the whole way so possibly does have higher capacity as itwas expelling the energy faster.
Interesting that the conclusion was that regular batteries last longer than rechargeables. I used to use a portable CD player that took AAs and that would play 2-3x the amount of albums with rechargeables over regular batteries.
Nice Test! One question Tyler, as rechargeable batteries have in general 1.2volts compared to 1.5volts on regular alkalines, how this lesser voltage impact on a flashlight supposed to run on 1.5v batts?
I've used the rayovac and the energizer rechargeables to make battery packs for my RC cars because replacements are no longer made. They work great. I use staples as the links between cells. I have some of the USB rechargeable cells but they cap out at 1,000mAh which isn't much good to me. I took the little charger circuit out of it and made a mini AA charger but it doesn't work that well.
Tyler I want to say I really appreciate your channel You put in a lot of work that a lot of us aren't willing to do and nobody's paying you to do this at least amazon's not paying you or duracell is not paying you... It's like a consumer report.... If we had videos like this in the eighties and nihe's that we're easily accessible there would be a lot of products that just never made it as far as they did because people would be able to give their honest opinions... I'm glad that crap products get called out... If you're gonna make something crappy be honest about it a lot of people are still probably going to buy it... Or make something not crappy.... But yes a lot of people are gonna run out and buy the drill driver that's only thirty bucks because they have three projects they need to get done and they don't need to spend two hundred and fifty dollars on a drill....
Wow, you've come a long way with testing products! The rechargeable batteries I use are Energizer and Rayovac. Only because they have been most available in stores. And in the beginning ( almost 10 years ago) these batteries were everywhere in stores! Now you have to hope you can find some. I think the reason is because they're so damn good. And the products you use them in are so much better at not draining them. Like xbox controllers. I have only had to buy these batteries once every two years. just to replace the ones that don't keep their charge as well. But in all They give many years of use compared to disposable batteries. So my personal opinion. If you have a remote control to a device you seldom use. Like a tv remote. use a disposable. If you're using anything like a head lamp or a game controller, buy a rechargeable.
It's been a year How did they hold up? Im looking for more rechargeable batteries, I went with the green amazon and man they suck, I gave up using them and went back to normal batteries but with Prime just 2 days away im looking again,
Brilliant Test Results. I love the Fan speed. I could almost feel the breeze from my Laptop.... Lol. But I am glad I have bought PowerCell ones as they seem to be quite good in your test. Nice work Tyler. We look forward to seeing you in 2025 with the ultimate discharge/recharge cycle.
The AA with a USB connection is likely a 3.7v cell, stepped down to 1.5v and shuts off once it drops below 1.5volt, it's part of its design to protect itself, the actual cell probably shuts down at 3.0volts. These types of cells unlike normal nimh don't like running down until they are flat, it's a different chemistry used.
one thing to mention is reliability, even more so then compacity or "value for mAh" is reliability. Power Owl is somewhat notorious for being quite unreliable with many stories of the batteries "exploding" when being recharged; more so then other brands from what I have read. For these batteries to be worth while over just buying standard disposable batteries, they need to be exceptionally reliable and able to be successfully charged many times over and and that's ultimately what you are paying for when you get something like a Duracell is it's marketed reliability. A couple of brands that I'd like to see tested is Walmart's Sam's Club house brand "Maker's Mark" rechargeable batteries as well as what is supposedly "the best of the best" rechargeable batteries on the market; the Panasonic "Eneloop Pro" batteries that supposedly give the best compacity, charging, and possibly reliability of them all but at a very steep price (up to $25 on Amazon for 4 AAs which makes those expensive Duracells look like a bargain in comparison).

The MC3000 would analyze the magic smoke battery just fine man. Check it out. Also, you should cycle the batteries multiple times, because the capacity most likely will increase after a few cycles in most cases.
was a bit surprised you didn't have any Eneloop batteries, those have been said to be the king of rechargeables and i have to agree.
@@kfin45 triple aaa? AAA AAA AAA??? I’ve never heard of that battery
Try the habor freight batteries I wanna see how they are never tried them
Draining and recharging the batteries once a day is a hell of a commitment to make! Glad to see you're so dedicated to this!
Yeah not worth it in my opinion.
worth it
Every bit worth it if you have a favorite flashlight that uses double a or similar batteries or other high drain devices
People drain and recharge their phones everyday.
Yeah well let's wait to see if he is actually going to release the follow-up video... Only about 3 months left. I am kind of bummed he did not include the Eneloop
Finally! Tyler starts an episode by ACTUALLY CHARGING THE BATTERIES FIRST!
Ayyy 🤣
I mean, rechargeable vs non rechargeable
@@intelatomtmYeahhhhh
Not sure what he's on about
Probably gave him the idea for the video. Instead of one of those "you guys complained so I'll do it again" model. I'm not mad at it.
How boring
I can't believe you didn't include Eneloop batteries. Best rechargable battery hands down. Eneloop has 2000 mAh. My oldest Eneloop batteries have lasted over 10 years so far. They still have over 60% life, which is leagues better than most rechargeables. So for longevity Eneloop might be the best, but I haven't read reviews of other batteries.
Agree. Should have included Eneloop batteries. They seem to be the most popular and the only ones I use.
My Eneloops have lasted 8 years so far. Hell of a brand.
He actually did in an older video lol bout 3 years ago
What about Ikea which some say is identical to eneloop.
@JustinBallard117 is that a serious question? Eneloop is godlike.
Tyler, that "AA Battery" is a lithium-ion battery. It has a regulator to drop the Li-on 3.7 volts to 1.5 volts. When you tried to charge it with a nickel metal charger, you probably damaged that circuit, and possibly the battery itself. That type of battery runs at 1.5 until it can no longer provide 1.5 volts, then it shuts off. That's why it acted the way it did when you tried to use it to run the fan.
Its a tight package, but that regulator should have had a blocking diode
Probably why the runtime is so short, they have to fit extra stuff in the same space.
I bought 16 Tenergy 2800 mAh AA batteries (and eight AAA Tenergys) and the Tenergy eight bay battery charger from Amazon. And as a ham radio operator that has insane experience with Nickel-Metal Hydrides for 30 years, they are the best ones I've ever had by far. You can leave them in a radio or whatever or leave them on a shelf and they hold their charge so much better than any I have ever owned.
Holy shit, that's quite a commitment. I'll be looking forward to the future test in a year. Keep in mind if you want to get through 1000 cycles in a year, you'd have to charge and discharge them 2-3 times a day.
I've got 20 year old every ready dual nicad, nimh battery charges and AA battery's 15 years old, that are charged daily for use in a portable dab radio, and right now they last about 45 minutes after a 4hr charge, they use to last approx 3 hours, same batteries..
So if regularly used can last a long time, I've also got nicads over 20 years old in an outdoor solar light, that comes on at dusk and charges during the day, these now last about 30 minutes when they use to last through the night..
did the 1000 chargingcycles with the EBL AA Batteries over the past 5 Years, Bought 8 of em, 5 are still doing great. I use them in my Camping lamp which I actually use as my Bedroomlamp 😅 It eats a set of Batteries every 3-4 days so yeah I get close to the 1000 cycles. The AA's do last but the AAA's from EBL died away like fruitflies within 2 years. Replaced them with Powerowl and "Tedi" branded rechargables and I have to say I am absolutely blown away from the Tedi branded ones, they still have their claimed capacity after 3-4 years
I noticed you didn't use Eneloop a Panasonic brand. I've used the same set of 8 batteries for about 10 years or maybe more and they're still decent batteries for wireless gaming controllers.
i agree. i have a set of eneloops and have been pretty impressed with them
where did you buy yours?
You should definitely re-run the capacity test and record the results every month or so throughout the year if you didn't already plan to. also, could be interesting to see which batteries get the warmest when fast charging and in use
Panasonic Eneloops are my go-to rechargeable batteries. The standard white ones and “pro” black ones have served me well for years. I wonder how they’d fare in this test.
The whites are rated a 2000 and pros at 2600. Even if they met those marks, the value isn't really there. The pros are $4.61 per cell right now in an 8 pack. They would have to really make up for it in longevity or low self discharge or something.
This, I feel like noone brings this up the Eneloops are so damn expensive for 4 Eneloops you get 12 of those Amazon's ones that are 2400 they are clearly a much better value even if 1 or 2 of them died, they have a close enough capacity and they're cheap
@@F0XD1Estandard ones are the best they last a butt-ton of time
that is a crazy commitment to charge and drain those batteries every day! thank you for having the dedication to make all these projects into interesting fun videos :) I’ll be looking forward to the follow up video!
Or he will just have a crazy cool breeze blowing through his house and live in luxury
still waiting lol
@@MerkMonarchX right 😭 i wonder if it’s in the backlog or those batteries are forgotten somewhere in the garage
@@samisbasement very well possible with this man 😂 we will either never see them again, or a video 7 years later
I can tell you what was happening to him at 1:50, he was trying to sneeze. He was trying to use looking at light to force a sneeze cause his nose was tingling. He may have photic sneeze reflex like I do, which means heavy eye stimulation triggers sneezing. It's actually quite useful when you feel the need to sneeze.
Ah man light sneezes are the best
i have the same thing!
5:40 the usb recharge battery is a lithium battery with a buck converter to drop it to constant 1.5v. when the internal lithium 3.7v battery "dies" gets below it's minimum voltage cutoff the buck converter just shuts off the output.
To promote battery lifespan and reduce the risk of handheld napalm fans, rechargeable batteries have battery management systems (BMS). These are what control the charge/discharge rates and levels of the units. That is why the fans just shut off at a certain level instead of fading out. It is also why the operational maths aren't necessarily a direct reflection of mAh. Great job! I appreciate you informing me that I bought crap batteries. :)
Interesting great to know.
Lower capacity batteries are often longer lasting in terms of cycles so are useful in some situations like TV remotes.
Doesn't make sense, you don't need more charge cycles if you are not charging them. Better buy cheap or low self discharge like Eneloop.
@@Xrayfk05 except eneloop do a normal version and a high capacity version (pro) for that very reason. The normal ones rated for 2000 cycles, the pros at 500 cycles.
@@EspadaMK I have both of those batteries, I use eneloop's for my VR controllers. They are at 1.4v when they come off my charger and maintain the voltage for longer, they don't suffer droop like other batteries.
It's the same with 18650's as well, I have high and low capacity and the largest, and most expensive, show significant degradation after 500-800 cycles as well.
When I clicked on this video I was expecting a topic on which rechargeable battery is the best, however I walked away with vast knowledge on the finite universe in which we reside. Truly peak performance, what others see as a grain of sand in a desert on this UA-cam platform, I see all the atoms and molecules which reside in said grain. Thank you for blessing us with this. Also tiddy.
Thanks for taking the time to do this. Well documented testing and research. Really helped me make a decision on which rechargable to buy.
Hey Tyler! That weird battery with the USB-C port said 2600 “mWh” or milli-WATT-hours. That, with 1.5 V, equates to 1733.33 mAh.
Great video man!
New Camera? I can't remember your videos being this crisp
I came here to comment the same thing. Glad someone else noticed.
Ya I was about to say mwh and mah are not the same
It's also a Lithium battery.. Not Nimh battery.. That's why the first one fried in the charger! I take it Tyler doesn't read the description on Amazon..
@@Tig3rj Thinking of "the average person", if it looks like a battery it probably charges like a battery. Unknowingly those people create an incendiary device...Who reads chinglese descriptions?
Excellent test. I just bought a 24 pack of Amazon rechargeable aa’s and a 24 pack of rechargeable aaa’s. Came here to justify my purchase and now I feel even better about it, thanks
Draining and recharging the batteries once a day is a hell of a commitment to make! Glad to see you're so dedicated to this!
Good work. I'm surprised you didn't try Eneloop or Eneloop Pro by Panasonic.
Yes, I noticed that, too. I'm very happy with the Eneloop batteries I've used for the last 10 years. They are 1,900 mAh, and they only take 3 hours to
recharge. I was surprised when Tyler mentioned that he was going to recharge his batteries for 12 hours! That seemed rather excessive to me.
@@jim6214 The estimated 12 hours was for a charge-discharge/test cycle.
1:47 Looks like Tyler was in recharging mode.
I didn't read all of the comments but the regular Duracell battery is 1.5V and most rechargeable batteries are only 1.2V. Something to think about there. Thanks for doing this test!
Hey Tyler, awesome test!
In addition to the life cycle test that you intend to do, could you do a long term test where you charge them, leave them for several months or a year inside a flashlight without turning it on and then testing what capacity they have left after such time and how long they last? Maybe you could leave one unit of each battery inside a flashlight and another unit of each battery in their plastic case without making contact with anything to see if there’s a difference.
I feel like with every rechargeable battery I’ve used, even though I always leave them fully charged, they usually die fairly early/not even hold any charge when I try to use them a few months after charging them.
Rechargeable batteries do die suddenly.
What kind of rechargable battery test doesnt include panasonic eneloop batteries, but includes dee lee pow?
A test that only tests dee lee pow lol
Never even hear of Panasonic eneloop ebr
thanks for testing/reviewing!
I've been off grid for many, many years and used a lot of different types of rechargeable batteries and I used to use rayovac and Energizer batteries but when I started using the thunderbolt rechargeable batteries they seam to last longer than the more expensive ones and also lasted longer in years of charging them.
Results also depend on fans motor quality, batteries' voltage (discharge curve - more voltage=more speed) and chemistry (this time there were only NiMH and a single li-ion):
* NiMH usually start at 1.4V then stay at 1.3-1.2V most of the time (fans with them will rotate slower and flashlights will be dimmer). And also since they're working at 1.2-1.3V most of the time - some smart electronics will think that betteries are almost discharged even on full batteries.
* Li-ion batteries (with built in 1.5V regulators and usb chargers) are running at locked 1.5V until they're completely discharged. I find them dangerous to use and even store - electronics inside them is very dumb and li-ion is dangerous when something goes wrong. But when they work they're VERY convenient - as they dont require special chargers and 100% compatible due to 1.5V output. Capacity is kinda meh because of all of the additional electronics in them.
* NiCd - terrible old technology, 1.2V, worse in all possible ways than NiMH.
* NiZn - spicy boys. Fully charged they start from 1.85V, then quickly drop to 1.6-1.7V and only right before full discharge it starts dropping to 1.4-1.5V. That means that fans will spin faster and flashlights shine brighter (but more stress on such dumb components, in rare cases can fry electronics). Smart-ish electronics will believe that battery is almost fully charged even when its almost dead. Some electonics that doesnt like lower NiMH volatges works better with NiZn than on Alkalines (normal batteries). Compared to NiMH their capacity varies depending on use case (can be worse or better).
I always get eneloops cause I read somewhere they are the best.
Here is one thing to think about. A different fan was used for each battery, which each could draw different amps. Nothing to noticeable, but maybe enough to effect the results. I wonder what would happen if Duracell and Amazon batteries switched fans, if you would get the same result.
Yeah this was one of the worst tests ive seen on UA-cam
The quality control on the fans is important, a slight difference in friction would change the results. Comparing two batteries at a time would mean the fans could also be tested.
The two fans with the closest characteristics could be identified.
Maybe take two makes of batteries at a time and have quarter finals etc
I like the idea of testing several at a time, but there are a number of parameters. Holding a charge over time, say a week, a month, three months ..
Lots of videos possible !
While you continue testing, could you do a shelf life test on the rechargeable batteries too? We would like to know after you’ve charged them to full capacity and they’ve set on the shelf for say a month, which one loses the most power?
Couldn't help but chuckle when I saw the cooked pasta stuck to the wall. I think Tyler is the only real tuber on here. Everyone seems fake or overactive. Tyler is one of us that made it.
Amazon Basics tend to be rebranded Eneloop. The higher capacity NiMh batteries are usually a little thicker than standard capacity and don't fit in all devices that alkaline will fit into.
It really depends on the build quality on the motors in every individual fan
I'm so happy that he's gonna do a year of charge/discharges, I figured he was just gonna ignore the longevity aspect. I would've been happy if he'd just ran the first test like 20 times in a row but dayum.
The lower output batteries are often cheaper. Both of those popular brands make bigger capacity batteries for more money.
Eneloop batts are great. They may not have the best capacity, but they always have great self discharge specs and maximum charge cycles. Amazon basics that I used in 2017 had a limited service life. I used AA Eneloops extensively in my job. Eneloops sold in N. America are made in Japan.
In the Market for a rechargeable, and you TEST is going to determine which one I buy. THANK YOU...very helpful show and test.
Air draft on both sides of fans that are standing in the middle of the row helps them to preserve energy. Fans that are on edgeds have that kind of helpful stream of airflow present only on one side. Maybe that contributed to the struggles of fan #1 and to the success of the Amazon battery.
It has been one year. Any ETA on an update? Making a big purchase soon. Would love to hear your results
I really needed some TylerTube. I was just watching Muta's cat video and was feeling way sad. But who could be sad watching Tyler test random Amazon stuff?
Something to also think about is longevity. How many charges and discharges can each brand do?
like I said in a previous video. Those Amazon Batteries are actually really good. They're just rebranded Eneloops. You're also 100% right about the PowerOwl's. They're pretty much the best you can get... if you dont get a dud. They do seem to have extremely bad QC.
Omg thank you! I asked for this video back when you tested the best normal batteries months ago. It was well liked. I'm glad you actually did this!
I've been using various rechargeable AA batteries for a 8 or 10 years now and while I bought some Duracell and Energizer here and there I've gone mainly with Power Owl after finding the Amazon ones occasionally slightly out of spec (short) in size causing the odd one here and there to not fit in all my AA needing devices which I put down to quality control at the source. I've seen reports of similar quality control issues with Power Owl in size but haven't had any trouble with the several orders I've placed in the last couple years.
For NiMH, the rechargeables that get a lot of press are the ENELOOP brand. I have more recently been getting good value from some LiION rechargeable AAs.
it is almost time
This test is probably one of your absolute best this year. Seems completely serious and a test you can actually benefit from, even in Sweden, where I am.
Thanks!
Was the garage cold when testing? I literally just watched another video testing rechargeable AAs and the NiMH from Amazon Basics did the best. For a cheap, rechargeable battery, they seem to be of decent quality.
SO EXCITED EVERY TIME ❤❤❤
The USB C prot battery is a lithium battery dressed up as a AA battery, they sound good but because of the added voltage stuff in it the capacity sucks pretty hard and they waste a LOT of power in the conversion from 3.7V to 1.5V. they also only tend to last a handful of recharge discharge cycles before they clap out.
Yea, when I saw that it only lasted a couple hours and went from going strong to an immediate stop. I knew it was a lithium battery.
YOU CAN BUY 14500 BATTERIES WHICH ARE BASICALLY AA BATTERIES , but run at 3.2 to 3.7 volts like an 18650. that way you dont lose battery capacity on extra electronics to downgrade the voltage to 1.5. Then they sell dummy batteries , so if your flashlight usually uses 2 aa's, use 1 x 14500 and a dummy and you'll get a slightly brighter beam and long lasting. just charge them in a li-ion charger
I would recommend going off percentages instead of the milamps.
For the charge and discharge. I'd also suggest getting those solar puck lights and throw them outside. It'll drain and recharge and show how the weather treats the batteries.
Great job! Confirms Power Farm's videos from years ago. Thanks!
not trying to defend trash where the label applies, but the usb charge one was 1.5v, while the others were 1.2v batteries. in some devices it matters, in the vast majority of devices it doesn't though. just pointing that out as a downfall of rechargeable batteries are typically 1.2v. great video as always tyler :D
How durable is the insulation? Is it so tight and soft that rubbing against the device going to peel it off and cause a short? Big problem with rechargeable flashlight batteries
3:09 there’s always some sound coming from somewhere in his videos lol and his reactions to it is just priceless lol
EBL barely holds a charge over time either. A note here, you can just about tell the capacity of a cell by weight in grams. The heavier the more output.
The USB chargeable ones are actually 3.7 lithium Ion cells, regulated down to 1.5 volts.
I would buy Amazon basics. However there is one more test, which is consistency. Will another battery from the same pack perform the same or are there inconsistencies?
How are you going to do a recharge test and not included enoloop
Hey thanks for the video! Good stuff here. I just have a couple notes on your test method. In terms of the fans you used, they are all the same which is good but there could be different motor resistance inside each, causing different batteries to have different loading. Also, the pitch of the foam blades may not be the same on each because of the flexible foam. That would also cause different loading on each battery. Lastly, the two fans at the ends, experience different aerodynamic loading due to the Coanda effect. Essentially the two fans at the ends experience a higher load, which may be why the Duracel didnt last as long, despite having a larger capacity.
One last note, each battery chemistry has a certain discharge capability. That might be why some of them have lower capacity while being the same size. I think I read somewhere that capacity is inversely related to discharge rating.
hi sinisterblack have you become a flat earther yet?
Could put fans in a circle.
It would be awesome if u also included the panasonic and sony batteries
Very good vide by the way❤
I have been waiting for this video since the non rechargeable battery video. I went out and bought Thunderbolt Edge batteries after that and they work like a dream. It was the first time I'd ever gone into a Harbor Freight store too.
Tyler can you make a video with summer time water guns/items
No tenergy or eneloop....c'mon man, get it together.
Are you sure that oddball battery with the USB-C charging isn't a lithium type? I don't recall seeing a NiMh battery with that charging port.
The rechargeable (nimh) perform better at higher power than standard (alkaline). I assume the fans are pretty low draw, it would be interesting to see some cheap high power flighlights or something to test along with the fans. Eneloops are the best, and any made in Japan AA is probably a re-wrap of the same quality.
lithum rechargeable AA are 1.5v normal AA voltage. but they provide the same current till death. wear the others are 1.2v as they dye there current slows till death
Should have thrown Eneloops in, they're one of the most popular rechargable batteries.
So, someone probably mentioned this at the beginning, but in case they didn't... the usb charging battery is lithium. From what I've gathered while trying to see if rechargeable was worth investing in, the battery is natively 3.7v and has to have resistors/capacitor to bring the voltage down to the usable 1.5-1.6v range (and there is some loss when going through this)
But when the capacity was listed it was in mWh instead of mAh, which since it is a different native voltage, is not as useful to compare. Instead most NiMh batteries are closer to 1.2v (though I'd like you to check 🤔)
To compare them fully you'd be best served by multiplying their stated mAh by their actual voltage. (it might even explain the slight difference between duracell and amazon) but then all bateries capacities would be listed in mWh for apples-to-apples comparison.
Lastly, lithium are much better at providing full power till fully discharged, but also dealing with circuitry to step down the voltage, it might artificially cut it off even though it still has electrons "in the tank"
This whole discussion has me intrigued, seriously it seems like the lithium would be great if they prioritized creating a cemistry from the ground up that matched 1.5v instead of jerry-rigging something to work or using NiMh at a lower voltage... both seem like they're trying to make sure they don't canablize the existing alkaline industry...
So as long as the "big battery" mafia doesn't come knocking on my door, I look forward to seeing if any of these batteries can come close to their cycle ratings!
07:26 its the Internal Resistance that affects them
You need to do each test multiple times. There will be variances. Then figure the statistics of the tests.
The endurance test with the fans is neglecting the variances in the fans themselves. I'd switch the batteries in the last two fans and run the test again (multiple times).
Yeah, I know, it would be very time consuming.
hi rogue have you become a flat earther yet?
I actually use the ebl, and they are incredibly durable. Been charging and recharging then for over a year. Well worth the money. And they have decent capacity, but it's not a big deal anyways, since you can just get a bunch of batteries, and charge them all up, and your good to go. The reason why i mental durability, is because they won't last forever, eventually they will stop working. So you have to check how many charges they are good for. So i know the ebl will work great
aww u didn't test my favorite Panasonic Eneloop i been using the same batteries for over 5 years for my oculus touch vr controllers and they only seem to die around a week or 2 earlier than they originally did when new, would be interesting to see tests on these
I love the battery testing videos! 😀👍
Each individual battery's capacity could vary a bit. In a test like you did with the fans, 50mAh-s or so counts quite a bit. If you didn't use the exact same batteries wich you tested previously for capacity, maybe that's why the Duracell died before the amazon basics. It could be from a slighty worse batch, or the Amazon basics could be from a slightly better.
Duracell VS Amazon, difference is in the internal quality/efficency.
Example a clock use way less energy than a fan motor so maybe on a clock Duracell could have lasted more in theory. Because the more energy you demand the less is the usable capacity of the battery. Is called "C" factor. On data sheets is always indicated the "C" factor used to determine the capacity (ex. 2500mAh). If you discarge the battery at a "C" higher than the "C" used during the capacity test, the capacity will be less. For this reason the Duracell lasted less than the Amazon...because the Amazon is better made and more efficient than the Duracell. Also with fast charging (like fast discharging with fan) Amazon is way more efficient than Duracell and can absorb the high amount of energy better.
Amazon batteries are superb for the price, better than any other you can find. And in your video you are using the "Amazon High capacity" that are the worst of Amazon. The "Basic" have around 20% less capacity but are always ready to use (after 2 years unused will keep almost 80% of the energy, so self discharge is quite null, like eneloop and can be recharged 1000 times compared to the 500 times of the High capacity). Now Amazon transfer production in China but Amazon NiMh battery bought some years ago reported a good "Made in Japan" label. So only Eneloop and Sanyo are made in Japan and in my opinion the Amazon NiMh was relabelled Sanyo, now transferred in China for contain price.
At the moment Powerowl cost more than Amazon basic batteries so there are no reason to buy something different than Amazon Basic batteries. Amazon High capacity batteries cost few cents more than powerowl.
The USB-C AA batteries are trash. They have internal Litium battery (like powerbanks) with internal charge controller. Since Litium battery will damage/explode if discharged or charged too much, the internal charge controller simply turn off the DC/DC converter that put out constant 1,5volt needed for a typical AA battery when internal litium battery is too low (typically around 3,2 volt), and stop the charge when internal lithium battery reach around 4,2 volt. This make these kind of AA lithium battery very dangerous (100% are from unknown chinese manufacturer without any warranty for safety) + the internal charge regulator and DC/DC converter use 30% of the space so will not leave too much space for the litium battery that is really small. In fact lasted less than all and will turn off instantly without any advice when internal lithium battery is low. Secondary the internal DC/DC converter needed to convert the lithium variable tension between 3,2/4,2 volt to 1,5 volt and will produce hot due to joule effect so for not burn itself the DC/DC will have for sure a power limiter (like that putted inside powerbanks and smartphone charger) so in a thight not vented place like inside an AA battery I think the AA USB-C battery can not handle more than 500mA of current compared to the several thousands of mA that a normal AA battery can delivery (starting current). So for understand better, as example, is you put 8 USB-c AA batteries inside an RC car, you will play really few time and maximum speed of the car will be really poor (for the internal battery current limiter). With normal AA nimh battery RC car will run way faster since a toy like that can run 15 miles per hour and for sure will draw from battery more than 3000mA (starting current) when accelerating. With USB-C AA this current is strongly limited.
Tyler’s brain rebooting killed me lmao
You should have had Eneloop and Eneloop Pro in the mix. They're supposed to be some of the best rechargeable batteries that money can buy.
I've never properly tested them, but in my own experience, the regular Eneloops have worked way better for me than rechargeable Duracell or Energizers.
I love your videos for many reasons but one of the main reasons is you are doing these tests because you genuinely have no idea what the results will be and want to find out yourself. Me (and all the viewers) love seeing your reactions. This channel is so great simply because it is your average Joe(Tyler in this case) testing things. Keep doing what you're and please never change. Hands down favourite channel
See if love to say this works and is credible but you ran only one battery. You kinda have to measure a sample size to compare given values such as capacitance or run time. Still I think it good analysis for only compare one type of battery each.
Great videos as always
i guessing the usb c one is lithium so it will just hit a wall quickly. im assuming the others slowed down. the lithium would stay flat out the whole way so possibly does have higher capacity as itwas expelling the energy faster.
You need to test them 3 times recharge then do it over ...need more data
Tyler I've probably seen every single video you've uploaded and I've been watching for the past 4 years thank you for everything you do.
This was good. Thank you.
Interesting that the conclusion was that regular batteries last longer than rechargeables. I used to use a portable CD player that took AAs and that would play 2-3x the amount of albums with rechargeables over regular batteries.
Nice Test! One question Tyler, as rechargeable batteries have in general 1.2volts compared to 1.5volts on regular alkalines, how this lesser voltage impact on a flashlight supposed to run on 1.5v batts?
I've used the rayovac and the energizer rechargeables to make battery packs for my RC cars because replacements are no longer made. They work great. I use staples as the links between cells. I have some of the USB rechargeable cells but they cap out at 1,000mAh which isn't much good to me. I took the little charger circuit out of it and made a mini AA charger but it doesn't work that well.
Tyler I want to say I really appreciate your channel You put in a lot of work that a lot of us aren't willing to do and nobody's paying you to do this at least amazon's not paying you or duracell is not paying you... It's like a consumer report.... If we had videos like this in the eighties and nihe's that we're easily accessible there would be a lot of products that just never made it as far as they did because people would be able to give their honest opinions... I'm glad that crap products get called out... If you're gonna make something crappy be honest about it a lot of people are still probably going to buy it... Or make something not crappy.... But yes a lot of people are gonna run out and buy the drill driver that's only thirty bucks because they have three projects they need to get done and they don't need to spend two hundred and fifty dollars on a drill....
I bet the Amazon item suggestion on what you might like to purchase is just.... amazing. LOL
Especially after the love hammer
Wow, you've come a long way with testing products! The rechargeable batteries I use are Energizer and Rayovac. Only because they have been most available in stores. And in the beginning ( almost 10 years ago) these batteries were everywhere in stores! Now you have to hope you can find some. I think the reason is because they're so damn good. And the products you use them in are so much better at not draining them. Like xbox controllers. I have only had to buy these batteries once every two years. just to replace the ones that don't keep their charge as well. But in all They give many years of use compared to disposable batteries. So my personal opinion. If you have a remote control to a device you seldom use. Like a tv remote. use a disposable. If you're using anything like a head lamp or a game controller, buy a rechargeable.
Awesome video. Tell us what chargers and testers you are using. Maybe I missed that in the video. A link to Amazon would be cool. Thanks, D.
It's been a year How did they hold up? Im looking for more rechargeable batteries, I went with the green amazon and man they suck, I gave up using them and went back to normal batteries but with Prime just 2 days away im looking again,
Great job! Thanks for doing all that legwork
You left out the best rechargeable AA Eneloop.
Brilliant Test Results. I love the Fan speed. I could almost feel the breeze from my Laptop.... Lol. But I am glad I have bought PowerCell ones as they seem to be quite good in your test. Nice work Tyler. We look forward to seeing you in 2025 with the ultimate discharge/recharge cycle.
I threw a 100 pack of used rechargeable batteries away because I forgot they were rechargeable 💀
The AA with a USB connection is likely a 3.7v cell, stepped down to 1.5v and shuts off once it drops below 1.5volt, it's part of its design to protect itself, the actual cell probably shuts down at 3.0volts.
These types of cells unlike normal nimh don't like running down until they are flat, it's a different chemistry used.
one thing to mention is reliability, even more so then compacity or "value for mAh" is reliability. Power Owl is somewhat notorious for being quite unreliable with many stories of the batteries "exploding" when being recharged; more so then other brands from what I have read. For these batteries to be worth while over just buying standard disposable batteries, they need to be exceptionally reliable and able to be successfully charged many times over and and that's ultimately what you are paying for when you get something like a Duracell is it's marketed reliability. A couple of brands that I'd like to see tested is Walmart's Sam's Club house brand "Maker's Mark" rechargeable batteries as well as what is supposedly "the best of the best" rechargeable batteries on the market; the Panasonic "Eneloop Pro" batteries that supposedly give the best compacity, charging, and possibly reliability of them all but at a very steep price (up to $25 on Amazon for 4 AAs which makes those expensive Duracells look like a bargain in comparison).
I got the EBL’s. I got 8 AA and 8 AAA for like $40 and couldn’t be happier with them!
