The higher the capacity battery, the fewer charge cycles it can go through before dropping in capacity so sometimes it's worth getting the slightly lower capacity but being able to have way more charge cycles overall.
Yes, I agree. One thing I have learnt through this process is that different rechargeable betters work better in different applications- such as you mention. I will follow this video up with my AA Lithuim-ion rechargeable battery test, which also has very specific applications.
The brand reports that there battery will last over 2,000 cycles. But of course there are many variables to consider. There are actually other brands that report even more cycles. Obviously it is a very hard thing to test for.
@@Bennett_Hennessey oh okay I was just going off a few brands I know of, though I'm still sceptical they are telling the truth on on longer cycle count
I have fully switched to rechargeable. Now I don't have to keep as many batteries around. At first I had to debate it because of the cost of the batteries, and charger. I am very happy that I switched. Oh and I also bought a small solar panel that runs one of the chargers. That has already come in handy because I used it to recharge my phone when electricity was off. I definitely believe it was a good move. Nice video, and I back what you are saying.
The cost and the voltage are both different. Most people do not realize standard rechargeable batteries ate only 1.2 volts while most disposable batteries ate 1.5 volts. This can be a big deal at times.
In my experience with numerous brands of NiMH rechargeable batteries, they can be charged to about 1.44 - 1.48 volts, well above the nominal 1.2 volts. NiMH cells are also said to have a lower internal resistance than alkaline batteries, but that's where the positives end for me(and where I originally intended to end this comment). The problem is, despite the advertising, all rechargeable batteries self-discharge at a rate that makes actual usable runtime much lower than advertised. After having purchased dozens of rechargeable batteries from at least four different popular brands, I have to say that I am NOT a big fan, and unless you're a person who likes charging and recharging batteries every month, I would avoid them. I am going back to regular disposable batteries with each new purchase and rather regret my foray into rechargeables. Also, some people may not know, but rechargeable batteries will NOT last forever, or likely even ten years. Even if they can be recharged over a thousand times, they'll probably only work well for 5 - 7 years tops, so don't think having a hundred rechargeable batteries means never having to buy batteries again, it doesn't. You'll probably get between 3 - 5 years and the joy of recharging batteries every month or two if you want them to be well-charged. Personally, I don't enjoy recharging and changing batteries that often, especially not in all of my devices.
For both AA and AAA batteries, the best rechargeable battery for 98% of you consumer needs (SEP21) is the Eneloop- both the standard or you can get a bit more lasting power with the Eneloop Pro. These are high quality products using a well tested technology.
Question: do you need the charging dock to recharge these? I bought these for my Xbox controller and they aren't recharging when i plug my controller in
You should be able to recharge NiMH batteries in all types of NiMH battery rechargers. Lithium rechargeable require a Lithium recharge (for the smart element of knowing when to stop charging the battery). So, no, NiMH rechargable batteries do not require any special type of recharger.
Your advice was really very much helpful and I greatly appreciate it very much for your help and time for making this very helpful video keep up the good work 👍👍👍👍
I think the general issue is that some devices you want to plug in batteries and forget about it. Example being TV remotes where you would only replace it every six months. Then there's devices that are tedious to replace like wall clocks.
I noticed some of the spent alkaline batteries in your video had some leakage, have you experienced any leakage on any of your depleted Eneloop batteries?
Excellent video you deserve a lot more views! I ordered $1.5/ea Amazon Basics AA 2,400 mAh and their $1.21/ea AAA 850 mAh "High Capacity" NiMH batteries. I'm buying enough to replace only remote and daily on LED candles. What I'm not a fan of is 1.2V vs 1.5V on NiMH so I'm looking at are Lithium AA and AAA. Question since this video have you tried Lithium AA and AAA batteries? Also what are your favorite rechargeables overall? Thanks 👍😊
After 2 years and lots of comments, the only clear problem is that NiMH batteriers are only 1.3 v, so I will be testing Lithium AA and AAA in the next few months and will make a follow-up video. I am very happy with the Enelope- but we will see what brand makes good Lithium batteries.
@@Bennett_Hennessey .. Since my comment I purchased two sets of AmpTorrent lithium rechargeable AA and AAA batteries. I like them because they went in their own charger as opposed to an octopus of USB connections. On Amazon apparently some people have done some extensive testing and posted their results. I'm just tired of throwing batteries in the garbage. Good luck and I hope to see your view soon.
Totally agree, just buy a smaller pack of rechargables and only use them for gaming so that you don't pay for more than you need (the bigger packs are pretty pricy) As long as you have spare batteries on the charger at all times you will be good. And for anything like your TV remotes, Camera's, Toys etc. ↓ Just use the disposables because I always find they actually last a decent while in those kind of things whereas in things like game controllers, mice, keyboards etc, they only last me like a couple days depending on what it is.
More and more, I am learning the really important part is the rechargeable battery you buy. The Duracell and Everready batteries are really bad and don't last. The Eneloop seems to be the best, so get that. All of my eneloop batteries are over 4 years old now, and keep on kicking,
Do rechargeable batteries (aa,aaa,9v, etc) get warm to touch when charging, is this ok? Is this normal or you should worry if is warm or if it get 🔥 to touch while charging?
This is a follow-up video I need to make. Some electronics are made for the top level of Alkaline batteries- so made to run at 1.5 volts each, and some are in series, like four together at 6 volts. It is a bad design. So, the non-lithium rechargeable batteries at ~1.3 volts, do not run such items very well. I have found this with some camera traps, a water meter. It usually happens with things with more than one battery in a series. The solution is to get Lithium recharge for such applications. But there a lot of drawbacks with lithium rechargeable batteries, so for most things you can stick with the general rechargables.
They are nowhere near 8 times as expensive. The number of recharges is greatly exaggerated. Even in a solar light which does a full cycle every day, you are unlikely to get 2000 charge cycles. But that's a best case. It's never going to last 2000 weeks in a more normal scenario where you have to re-charge them once a week or less frequently. They are just aren't going to last for 10 years of constant use. The chemicals break down over time.
I have a lot of rechargeable energizer batteries and they become dead ( means if I recharge it and try to use it , it doesn’t hold few hrs ) , and searching about this issue , many people mention the battery aging Then I returned to throw away batteries again , So any recommendations about the 20 plus rechargeable batteries I had ? What to do to make them work again efficiently?? Thanks guys in advance
I am sure many people have also had your experience with the horrible Energizer rechargeable batteries. I think you have to accept you got scammed by them, and buy the eneloop and you will be happy.
Most rechargeable batteries, particularly AAA ones are not able to re-charge. I purchased 3 pack of 4 AAA energizer (back in 2015) and charged it a few times. Mostly used for graphing calculator and remote control. And like 1 in 5 of the AAA wasn't able to charge and the charger's red light continued to flicker. Batteries are less than a year old too.
This is unfortunately the design plan by the larger companies that depend on selling "throw-away" batteries. They want the public to believe there is not an alternative. Try the eneloop batteries. Many professionals have been using them for years. They are an excellent product. I just bought 8 more, because I need them for new applications.
I have multiple “chinesium” rechargable batteries ive pulled from multiple things over the years. Almost all of them are completely fine and work great.
That is good to hear. I am trying out some dubious Lithium AA batteries right now- so far holding up OK. I just wish they would not claim lies on their packaging.
rechargeable batteries lose capacity and performance over time with repeated usage and charge cycles. Have you ever noticed that your phone battery struggles to hold a charge after 1 or 2 years of usage?
Right. They say it is not so much time, but the repeated charging events. But there are also better quality batteries that last longer, and charging techniques to extend the batteries life. Eneloop says there battery can be recharged 2,000 times.
Rechargeables lose noticeable chunk of ability to store a charge after HUNDREDS of cycles. That is nowhete near close to 1 cycle avaiable from non-rechargeables.
I'm a collector of older animatronic toys and electronics and I've always wondered why many of those say not to use rechargeable batteries. Is it because they're from the time of the nihm rechargeables which were low power and sucky?
This is the question I want to look into for a follow-up video. A NiMh AA rechargeable battery fully charged peaks around 1.3 volts, whereas a typical Alkaline single-use battery is 1.5 volts. That usually is not enough to make a large difference. But if the device is using four batteries in series; 4 x 1.3 v = 5.2 volts- whereas 4 x 1.5 v = 6 volts. The device will probably work, but not as long as you would like because the voltage will drop off. But since rechargeable voltages don’t drop that quickly, I would like to test that theory. But it will not harm your device, it just might not last as long. But the simple solution would be to use Lithium rechargeable batteries- which have a peak at 1.5 volts. At this point I can’t recommend which brand.
I've had rechargable batteries same ones for about 10 years or so.. I have 🔋operated lights for my 🏠 portable. I have battery cases so they do not touch and drain.
I don't think so for the average consumer AA & AAA battery because the demand is a very low level of electricity over a long period= where the speed to recharge is really not that important (overnight is fine). But if they are improved to hold more energy they could work for specific applications. It looks like the general Mi-NH rechargeable is good enough for most applications that it will stay around for many decades to come.
Alkaline has its uses. They are a very smooth discharge curve, the voltage starts much higher and they are not electronically noisy at all. Some stuff like a paintball guns for example can't use a NiMH battery, the voltage is just too low. Lithium ion is a good sub, however the circuitry in those is generally very noisy and a problem for things like guitar pedals and microphones and some sensitive electronics. Everything has its use.
Good points. I am testing some commercial Lithium batteries right now, but they do have the added circuitry which I could see adding noise. Will note that in a follow-up video. Thanks
@@Bennett_Hennessey Sweet! I just purchased a lithium ion 9v that actually holds 9.5 volts (most are in the 8v range) and I am going to test it for noise as well.
rechargeable batteries lose capacity and performance over time with repeated usage and charge cycles. Have you ever noticed that your phone battery struggles to hold a charge after 1 or 2 years of usage?
II live in Bolivia where the country is flooded with crap cheap batteries, so Duracell were the best Alkaline you could buy (funny, I have bought batteries for three years now). It is very humid here, so batteries corrode quicker.
Don't forget to add the cost of the chargers and electricity. I've switch to using lithium primaries in my lower demand/used devices -- no need for rechargeable in those devices. Alkaline batteries last forever in those devices but would run the risk of leaking and damaging them thus I replaced all my alkaline cells with lithium cells which don't leak, have a longer shelf life, and store more energy. i.e. bathroom scale; one set of batteries will last a decade; so there no need to put expense rechargeable batteries in it; plus if you do you'll have to keep charging them.
Good points. Could be hard to quantify which is really better in the long-run- depends on a few factors. I don't mind having made that investment and now- in theory- won't have to buy batteries ever again (or at least after 2,000 cycles).
@@Bennett_Hennessey The enloops are great batteries; I have some that are over 10 years old but no where near 2000 charges. I started picking up the pro version for my camera/audio gear.
Don't forget that recharge not always means quality. Eneloop are really good for actually keep the charge way longer, then a cheaper one. I had some cheap ones in the past, charging, and 2 month later, they was empty again(by NOT using them). So i bought recharges many times until i found eneloop. (the older white ones) I bought 2012 2x4 = 8 for around 30€ and i use them still to this day. I use them in Systems, like a Wii Mote, Xbox 360/One Controller, heck, even for my old Game Boy. I never bought any more batteries. And i know, the "other" thing is, that if you charge them, you use your electric at home, and yes, this is a small amount of meny you have to keep in mind that comes on top. But wow... how many batteries i would had bought over 8 years? And the sad news is: now my Litinium Battery in my GBA SP died and i have to buy a new one, because you can not use AA Batteries on this Version like the GBA (i hope ppl understand what im saying, because im more into Videogames :p )
why are they only 1,2 Volts tho. Many electronics require 1,5V otherwise they won't work (i.e my camera doesn't even turn on). That's the biggest issue for me. If you put rechargeables in a remote, the range is dramatically reduced, if you put them in a toy (i.e a car) it will go as slow as a turtle.
The NiMD Rechargeable batteries are 1.3v when fully charged. That is the nature of NiMD. That is good enough for 97% of your battery needs. But stupidly some electronics systems only work on 1.5-1.4 v, which is an Alkaline battery at its peak (very wasteful on batteries). The solution in those rare cased is to get a Lithium Rechargeable AA or AAA battery. Lithium naturally will hold a 3.4 v charge, so they also come with a built in controller to give constantly 1.5 v until the battery runs out of power. This is the case for camera traps, and some items that use four batteries in series. But for most of your needs a NiMD Rechargeable battery will be fine.
@@Bennett_Hennessey I only buy eneloop brand only other way I’ll ever buy energizer or duracell rechargeables is if they are ever on sale like last year 4 batteries and a charger for 10 bucks I bought 6 of each gave all of away as Christmas stocking stuffers for the kids told them to only buy eneloops I have most of my family thanking me now after telling them all over and over to only buy eneloops they love em now especially now that it’s saving them all big bucks over throw always
I'm not the best at sending. I've bought a smart charger in the.and I find if the rechargeable battery that is not been used for a very long timefor ages the charger will flash and reject the battery so I find I use a normal battery charger that isn't smart put the battery in it charge it up to the voltage in the smart charger will then accept the batteries and rechargeable batteries are normally 1.2 and disposable batteries are 1.5 and some brands of batteries are not the exact same size as as equivalent disposable battery
Probably depends on the smart charger. I guess that is the problem, a smart charger makes things easier for people, but can also make mistakes. But that problem outweighs the advantage that a smart charger won't destroy a rechargeable battery.
Adding a nice smart charger, you'll find the service life of those rechargeable batteries will last a very long time. You will also have more knowledge of batteries, their capabilities and proper applications in their use. Being an odd person, I find myself collecting various brands to compare each other too - kinda fun.
"Petro-chemical" engines are a "scam?" Try driving a 40-ton tractor-trailer coast to coast on wind or solar! ...maybe you could put sails on it!Sorry, buddy, but the storage technology (batteries) simply isnt there yet to make "renewables" a viable option for large scale applications!
Fully charged NiMH rechargeable batteries are usually 1.42 v, which is perfectly fine to run 98% of battery operated instruments. If they are lower- they might be one of the many poorly made cheap rechargeable batteries. If you must have 1.5 v, than you want to get Lithium-ion rechargeable batteries.
@@surenbono6063 There are companies that make Li-ion AA and AAA batteries. They have a controller inside to regulate the voltage at 1.5 v. I am experimenting with a few. They do not hold as much of a charge, and do not seem to be as well made as eneloop, but when you must have 1.5 volts they can work. I find the eneloop NiMH work very well for 95% of my needs
I did think about that. My nature in life is to try to be funny, but I think my lack of experience in video making and how people will react, makes me stick to the straight story.
MINE STOPED BEING GOOD AFTER 2 CHARGES. DURECEL. Have to say sorry to durecel. Had a defective keyboard that had a key stuck so it was always on. It was a key that wasn’t assigned to any function so it was unnoticed. I only found out after I tried reassigning a key and it was always on. So batteries were probably burnt out by it. Logitech keyboard. Made in China.
I do not have enough experience with different brands to say which is better, but I found people highly recommend Eneloop, which is what I bought, and I am very happy with them so far.
If your Duracell's stopped after two charges then I would suspect your charger is at fault. There's a video from I think it's called Project Farm and they're testing shows the duracelles is one of the best NiMH using solar lights and daily charging and discharging.
Eneloop pro AA (which I recommend) are online for $7 each in a four pack with tax. You can always buy cheaper ones, but cheap is cheap. I wanted to avoid stating a cheaper price and then everyone says I am not being realistic. The point is, even at $8 each, this is a far better alternative to throw-away batteries.
Thanks for letting me know. I checked it looking at the video from my other channels, and it was working without a problem. Maybe something to do with your site, place, IP address- I don't know.

Lithium ion is a good sub, however the circuitry in those is generally very noisy and a problem for things like guitar pedals and microphones and some sensitive electronics. Everything has its use.
Good points. I am testing some commercial Lithium batteries right now, but they do have the added circuitry which I could see adding noise. Will note that in a follow-up video. Thanks
@@Bennett_Hennessey Sweet! I just purchased a lithium ion 9v that actually holds 9.5 volts (most are in the 8v range) and I am going to test it for noise as well.
Very good overview, thanks!
rechargeable batteries lose capacity and performance over time with repeated usage and charge cycles. Have you ever noticed that your phone battery struggles to hold a charge after 1 or 2 years of usage?
Notice that many of his disposable batteries are Duracells? Did you also notice that many of them are leaking?
II live in Bolivia where the country is flooded with crap cheap batteries, so Duracell were the best Alkaline you could buy (funny, I have bought batteries for three years now). It is very humid here, so batteries corrode quicker.
Don't forget to add the cost of the chargers and electricity. I've switch to using lithium primaries in my lower demand/used devices -- no need for rechargeable in those devices. Alkaline batteries last forever in those devices but would run the risk of leaking and damaging them thus I replaced all my alkaline cells with lithium cells which don't leak, have a longer shelf life, and store more energy. i.e. bathroom scale; one set of batteries will last a decade; so there no need to put expense rechargeable batteries in it; plus if you do you'll have to keep charging them.
Good points. Could be hard to quantify which is really better in the long-run- depends on a few factors. I don't mind having made that investment and now- in theory- won't have to buy batteries ever again (or at least after 2,000 cycles).
@@Bennett_Hennessey The enloops are great batteries; I have some that are over 10 years old but no where near 2000 charges. I started picking up the pro version for my camera/audio gear.
Don't forget that recharge not always means quality. Eneloop are really good for actually keep the charge way longer, then a cheaper one. I had some cheap ones in the past, charging, and 2 month later, they was empty again(by NOT using them). So i bought recharges many times until i found eneloop. (the older white ones)
I bought 2012 2x4 = 8 for around 30€ and i use them still to this day. I use them in Systems, like a Wii Mote, Xbox 360/One Controller, heck, even for my old Game Boy. I never bought any more batteries.
And i know, the "other" thing is, that if you charge them, you use your electric at home, and yes, this is a small amount of meny you have to keep in mind that comes on top. But wow... how many batteries i would had bought over 8 years?
And the sad news is: now my Litinium Battery in my GBA SP died and i have to buy a new one, because you can not use AA Batteries on this Version like the GBA (i hope ppl understand what im saying, because im more into Videogames :p )
Yes, I agree, Eneloop really appear to be a high quality battery
why are they only 1,2 Volts tho. Many electronics require 1,5V otherwise they won't work (i.e my camera doesn't even turn on). That's the biggest issue for me. If you put rechargeables in a remote, the range is dramatically reduced, if you put them in a toy (i.e a car) it will go as slow as a turtle.
The NiMD Rechargeable batteries are 1.3v when fully charged. That is the nature of NiMD. That is good enough for 97% of your battery needs. But stupidly some electronics systems only work on 1.5-1.4 v, which is an Alkaline battery at its peak (very wasteful on batteries). The solution in those rare cased is to get a Lithium Rechargeable AA or AAA battery. Lithium naturally will hold a 3.4 v charge, so they also come with a built in controller to give constantly 1.5 v until the battery runs out of power. This is the case for camera traps, and some items that use four batteries in series. But for most of your needs a NiMD Rechargeable battery will be fine.
Those energizers and duracell recharable batteries r higher mah but they always die and r junk after a year maybe 2 years if your lucky
I just had the crap Energizer AA battery die on me after recharging less than 15 times in 2 years. What a scam they have going.
@@Bennett_Hennessey I only buy eneloop brand only other way I’ll ever buy energizer or duracell rechargeables is if they are ever on sale like last year 4 batteries and a charger for 10 bucks I bought 6 of each gave all of away as Christmas stocking stuffers for the kids told them to only buy eneloops I have most of my family thanking me now after telling them all over and over to only buy eneloops they love em now especially now that it’s saving them all big bucks over throw always
Thank u . Really helpful
Glad it helped
I got rechargeable batteries they were expensive with the charger but hey it saves me money in the long run
A lot of money. I could never go back.
This was very useful thank you
You're welcome!
Very useful video!
I'm not the best at sending. I've bought a smart charger in the.and I find if the rechargeable battery that is not been used for a very long timefor ages the charger will flash and reject the battery so I find I use a normal battery charger that isn't smart put the battery in it charge it up to the voltage in the smart charger will then accept the batteries and rechargeable batteries are normally 1.2 and disposable batteries are 1.5 and some brands of batteries are not the exact same size as as equivalent disposable battery
Probably depends on the smart charger. I guess that is the problem, a smart charger makes things easier for people, but can also make mistakes. But that problem outweighs the advantage that a smart charger won't destroy a rechargeable battery.
Adding a nice smart charger, you'll find the service life of those rechargeable batteries will last a very long time. You will also have more knowledge of batteries, their capabilities and proper applications in their use. Being an odd person, I find myself collecting various brands to compare each other too - kinda fun.
@AT0M Powerex or Skyrc
Intetesante video.
freaking awesome.!!!
Glad you liked it
"Petro-chemical" engines are a "scam?" Try driving a 40-ton tractor-trailer coast to coast on wind or solar! ...maybe you could put sails on it!Sorry, buddy, but the storage technology (batteries) simply isnt there yet to make "renewables" a viable option for large scale applications!
I think there is a whole building of engineers at Tesla that would disagree with your statement. I agree it wont be easy. but I think worth a try.
..I bought the wrong rechargeable batteries..it came 1.2 dcv.. 1.5 dcv are acceptable.
Fully charged NiMH rechargeable batteries are usually 1.42 v, which is perfectly fine to run 98% of battery operated instruments. If they are lower- they might be one of the many poorly made cheap rechargeable batteries. If you must have 1.5 v, than you want to get Lithium-ion rechargeable batteries.
@@Bennett_Hennessey ..those li-on are over 3.6dcv ..and the size are to big..I need AA & AAA sizes..to fit remotes..1.2v are not enough..
@@surenbono6063 There are companies that make Li-ion AA and AAA batteries. They have a controller inside to regulate the voltage at 1.5 v. I am experimenting with a few. They do not hold as much of a charge, and do not seem to be as well made as eneloop, but when you must have 1.5 volts they can work. I find the eneloop NiMH work very well for 95% of my needs
@@Bennett_Hennessey ..but that's not on my market...
The throw away batteries can actually be charged but with lots of caution.
if you made this video sarcastically, this might have been trending...hahaha your tone is funny when I imagine it on that way...haha no hate...peace
I did think about that. My nature in life is to try to be funny, but I think my lack of experience in video making and how people will react, makes me stick to the straight story.
MINE STOPED BEING GOOD AFTER 2 CHARGES. DURECEL.
Have to say sorry to durecel. Had a defective keyboard that had a key stuck so it was always on. It was a key that wasn’t assigned to any function so it was unnoticed. I only found out after I tried reassigning a key and it was always on. So batteries were probably burnt out by it. Logitech keyboard. Made in China.
I do not have enough experience with different brands to say which is better, but I found people highly recommend Eneloop, which is what I bought, and I am very happy with them so far.
If your Duracell's stopped after two charges then I would suspect your charger is at fault. There's a video from I think it's called Project Farm and they're testing shows the duracelles is one of the best NiMH using solar lights and daily charging and discharging.
Bamboozled, you say? Why, I've never...
$8 for a rechargeable battery? This is certainly a skewed report. There are much better options.
Eneloop pro AA (which I recommend) are online for $7 each in a four pack with tax. You can always buy cheaper ones, but cheap is cheap. I wanted to avoid stating a cheaper price and then everyone says I am not being realistic. The point is, even at $8 each, this is a far better alternative to throw-away batteries.
@@Bennett_Hennessey Disagree. Thats like saying a corvette is better than a civic, there is no practical relevance here.
After I jumped to the middle, after a couple of minutes, I came to the conclusion that I was wasting my time. Don't toss them around.
Thank you for your comment, but I don't understand what you want to say with "don't toss them around"?
$8 for a rechargeable AA battery? even 2 years ago thats bullshit
Your " like" button isn't working
Thanks for letting me know. I checked it looking at the video from my other channels, and it was working without a problem. Maybe something to do with your site, place, IP address- I don't know.
I have a AA rechargeable battery and it stocked for years is it ok to use and charge it again instead of buying a new one? Tnx
Yes. Just charge them up first and then start using. They should be fine.
