Damn dude. You teach, really, what needs to be known. Even I didn’t know that 18650 is the literal measurement of the battery. And I’ve been using them for years now
I have 16 Orbtronic 18650 (Panasonic cells) protected batteries for my various flashlights, and have been very pleased with them. The oldest among them being over 8 years and still going strong. I label mine A to P with a P-Touch labeler for easy I.D. I cant stress enough the importance of a quality smart charger, especially with auto discharge and ability to give a readout of the cells health/actual mAh capacity. Thanks for your comprehensive video in minimal time..
Agree, except sponsor mentioning, that is not fair to them, IF it is their sponsor as long as it does not skew the content, useless to you not them. It is not all about you or I. It is their living so cut a little slack.
Such an important video for anyone utilizing these cells, I see tons of vapers with zero knowledge of batteries who will continue to run them with rips in the wraps. This is among the many reasons we have venting and explosion horror stories in the media. This should be required viewing.
Did a right-fine job on this video, son. You might want to include the fact that, while rechargeable batteries are a good replacement in most devices, there will be quite a few instances where you really NEED that initial 5.8v-to-6v (4 X 1.5v cell) for the device to work, as a voltage of less than say 5.6v-to-6v (4 X 1.2v = 4.8v) just may not even turn the device on. In the last few years, there HAVE been rechargeable batteries that produce the same voltage as their alkaline counterparts, but for the most part, the voltage of the most popular Ni-Cads or Ni-MH are the 1.2v variety.
Good Point. I bought rechargeable 9 Volt batt kit for my basement water/flood alarms (placed next to sump pumps). The alarms would NOT work with them as the initial voltage was just slightly below that expected from a 9V Alkaline batt that the alarms designers based their product on. Got a quick refund on the rechargeables and bought some top-line alkalines. Both the rechargeable batt OEM and the water alarm OEM agreed on the problem. So, just a heads up -- research and test before setting aside rechargeable batts for contingency use or critical systems.
A good introduction, with something for both novices and experienced users. Most of my experience with rechargeable cells comes from the NiCad cell days. I remember learning to "zap" them to vaporize the metal whiskers to which they were prone. Good times!
There is a lithium ion rechargeable AA battery (1.5 volt) which I bought recently. Made by Hixon. The only problem is that because of the protection circuitry, the AM band is not listenable on portable radios. They're rated at 2333 mah. (3500 mwh).
You the man. Thanks for the information as always. Just wanted to say o purchased an olight seeker pro 2 after watching your reviews. I tell people at my job that you are the man when it comes to flashlights
ive been using tenergy standard D batteries (the blue ones) since 2007... theyve been overcharged, overheated i dont know how many times, discharged until completely dead over & over, the bottom ends dented in because i dropped my maglite too many times... they still work awesome after about 13 years... they are not low self discharge (they didnt have that for D's then)... so i just got a bunch of tenergy centura D's & so far they are good... i like the LSD NIMH, because you stash the flashlight & when SHTF, they are ready to use a year later, low maintanence
You're definitely a great help for me thank you so much for showing this I bought the mini pro it didn't come with a charger so it looks like I'm going to have to get a charger for it
Great video, I also use the Efest and Keeppower, but also use Panasonic, Samsung, and LG. Most of mine are unprotected I'm not a big fan of the protected batteries I have over 70 li-ion batteries and about the same number of flashlights. I get mine from Obtronics, IMR, Gear best, and even some from eBay and Amazon. I checked mine with opus bt 3000 v2.2 charger to verify their authentic. When I first started using these batteries like everyone else I went the cheap route and bought ultrafire 4000 mah when I put those in the charger they show about 300 or 400 mah.
I use XTAR Protected 26650's in my 2D mags with the 5000 lumen dropin. Ive also just converted an ML150 to accept a paiur of 26650's rather than the lower voltage LifePO4 pack that comes in it.
Hey buddy, love your channel. Had a question for you, what does AAA and AAA battery do you recommend? I just got a couple Olight flashlights and a couple other ones and they take either Triple-A or double-a and some of them take cr123 which brand name do you find to be the best in your technical opinion? Let me know when you get this body appreciate it long time since driver take care and be safe
Thanks Matt! I’m just getting into flashlights and I’m learning about all this battery stuff. Who knew?!?! I just bought my first two REAL flashlights (Thorfire Q8 and an Astrolux FT03) and ordered samsung INR18650-30Q 15A 3000mAh 18650 batteries. I read after purchasing them that they will not be ideal for the Q8, and that a 20A battery will let you get to the flashlights maximum output. Will there be a big noticeable difference between what I bought and the 20a? I also purchased a Nitecore i4 charger. This is a lot to learn! I haven’t received my batteries yet but I will research how to charge and take care of them. For now though I’m curious about the 15a and 20a difference
I have a flashlight. It was one of those retail store flashlights, like you might find close to the checkout counter. It came with a battery adapter, that holds four AAA batteries. I suspect that the adapter is a stand-in for some type of lithium battery, but I'm not sure what type the flashlight is really expecting. It's the standard "Tactical" configuration, that seems to be everywhere & sold under countless brand names. I'm tired of getting alkaline replacements for it, and if there is a legitimate rechargeable alternative, I'd like to find it.
All still good choices here. Top picks for today SonyVTC6 and the Keeppower 3120ma protected. Xtar SV2 Rocket is a great charger because you can charge 2 channels at 2000ma each.
When a double stack of heat shrunk 26650 rechargeable batteries go in a flashlight like the 100000 lumen flashlights on Amazon go can you buy single 26650 & put 2 in the flashlight?
Can I use a D size lithium ion battery in a flashlight conversion or do you recommend the 2-Pack (Card) Tenergy Centura NiMH D 1.2V 8000mAh Rechargeable Batteries as you mentioned in the video? Also do you recommend a nice bright LED? If so do you have a recommendation for an old 2 D battery conversion to lithium ion or the NiMH battery you mentioned in the video? Thank you😊
Great video, much appreciated. Also your other videos in general. I love flashlights, but noone else around me does. I just purchased a 2000 lumen bulb for my Maglite 5/6 D cell (I have an extension). Which rechargeable Lithium batteries will work for this? Is there any special way to set it all up? I can't find a specific video on your channel about this. Kind regards Thomas from Denmark
Hi , just bought a pair of Shockli 26650 's . Could you please tell me where and what kind of Charger I should buy ? Thank you , Sir , Much appreciated !!
I have an led torch using a flat topped 26650 battery and it’s went dead. What can I do to revive it? Would it be safe to do the drill battery trick with two forks?
I got a new 2022 flashlight that ce with a 26700 3.7v battery. Can I use a 18650 3.7v battery in it as a backup? Can I charge the 18650 in the new flashlight? Thank you!
Hi Matt, i still have a few Inova flashlights, old but well built and durable, i.e., inova x 5 and x 0. they run on cr123 batteries, expensive and non rechargeable. Is there any battery I can use to replace them? If there is, will they fit in my flashlights?
Looking for Rechargeable CR2 batteries and CR123A batteries for Duty use in a Carbine (Red dot sight) and handgun mounted weapon light. Looking for high mAh, recently bought some Ultrafire brand rechargeable CR2 batteries and CR123A batteries, are these any good? Do you have any recommendations for high mAh rechargeable CR2 and CR123A batteries?
Matt, I've got a Rovyvon E700u angel eyes that loses charge over a few days. It uses a 21700 Fenix 5000 mah battery. You have any insight to my problem?
Help!! I have a nicron n7 AA. It is supposed to take a 14500. I bought a klarus 800mah 14gt-80our and it will not work I fully charged it. I put it in a mag light and it popped the old buld immediately.. so its working..just not in the n7???
Hi i have got samsung 30q 18650 batteries 3.7v batteries and i have been having problems with them the first one i bought stopped being recognised by the charger and now i have one that when fully charged only reads 3.3 volts. They do get left in my torch over the summer unused is this causing the problem do you think?
I was charging 18650 cells with my phone charger and checking voltage often. I had 4 batteries and a roommate had about 100 he borrowed one and brought me a different battery. I started charging 5v 500 ma. Within a few minutes it started heating up so I took it off charging. About 2 minutes later it was shooting fire out the negative end. It flew and hovered spouting flame and gray residue. It lasted for a few seconds and Yoda was trying to get out of the room ( my 16 yr old Chihuahua). I never let anyone bring me a battery even though I was charging it on a homemade rig I never had a problem like that again .
NCR stands for "Nickel / Cobalt / Rechargeable" which designates it as a hybrid lithium-ion rechargeable battery. That type are used in electric vehicles, , electric bikes, power tools etc. but if you have say a Panasonic NCR18650B or the like, it can only handle around 4.9 amps CDR (constant discharge rate) so check the specs on your flashlight as you wouldn't want to use them in a high output/high drain light that's going to be pulling a lot of amps.
AtPro411 Thanks, very helpful. I have a few 18650s that are Sanyo NCR18650GA 3500mAh 10A. Have always wondered if these are as safe as IMR and INR chemistries. Sounds like they aren’t. Maybe safer than ICRs though?
Hi Matt, love your videos and your enthusiasm! Can I replace a16 340 1300 milliamp hour 3.7 volt cheap Chinese battery with a comparable better battery preferably lithium. To be honest I don't know if this thing is lithium or not.
I have a Sanford SF438SL-2SC torch Just the head I don't know which battery to use The manufacture I found saying 1900 mah 3.6 v ni-cad battery I can't find it or even online buy it Which li-ion battery can replace it
I have to say that in 2014,I purchased a flashlight that came with 2 ultra fires and a charger. I charged them when I received them.Used the flashlight a few times before storing it in my glove compartment..2 months ago.(2020) I remembered the light was in there and KNEW it would be discharged.., Man the thing lit up like the sun and is still working for me with about once a week uses ..Charged in 2014..lol
Personally I like SonyVTC6 button tops for an unprotected cell. The keeppower 3120 ma cells are a protected version of this. The K75 carrier is designed for protected cells so either the acebeam 3100ma or the keeppowers would be best. You can fit the unprotected cells if you stretched the springs.
I have a cheapy menards Guidesman 5w flashlight. I like it because if the flood and spot capabilities. Its bright. I look for addresses for work with the spot. Three questions. Can i get a different battery or two, replacing the 6 aaa batteries it takes? If not is there a better aaa battery than the EBL Nmh 1.2 v 1100 mAh? It seems it doesnt hold the charge all that long. And Last Is there a better slim profile not so long flashlight with spot to flood capabilities? My guidesman is just a bit annoying with putting in my pockets because the bezzel or head of the flashlight is wider and bulky, its a bit uncomfortable when sitting so it comes out of my pocket. Need something less in length (6 inches i belive its at) Thanks.
And what's the benefit of higher voltages, will the flashlight shine brighter? I mean, if I got a Li ion 18650 to use in my flashlight instead of regular alkaline AAs, or even rechargeable Ni MH, would it be brighter? Can I also assume that because of the larger size(of 18650s vs. AAs) that the batteries would last longer as well? Or does the size get "neutralized" because of the greater discharge/output amperage(if that's the right term)?
Using li-ion cells means that you get higher voltage but it also means the batteries can carry a heavier load (amperage). You should not try and put li-ion batteries into a device unless you know for sure it is made to handle it. In some AA size flashlights you can replace the cell with a 14500 size li-ion and it will be much brighter, but only if the driver board in the light is made to handle it. Otherwise you will burn it up.
@@Lumencraft- Thanks. I actually have a flashlight that takes two AAs, and it's pretty bright, but the seller said it actually can take 18650 batteries as well, but I'm a bit unsure about that, often times sellers don't put the correct information in their ads. Also, it's unfortunate that I cannot find a webpage for the company or product so I could check it out and get the info straight from the manufacturer.
This guy's cool...oh yeah, I've fallen for buying cheap 18650 batteries on ebay. I've never used them. I didn't know better at the time, but now that I do, I'm too nervous to try them.
Sometimes there is a reason batteries are cheap, like they are past their best by date. I am in the Philippines where we have plenty of blackouts. The best deal I have found lately is LG Choco 3000 mAh. The ones I buy are 19 months old and have lost some capacity, although never used. They are still 20A but are down to an honest 2600 mAh...but they only cost me $4 for two of them. My EDC light takes button top batteries so I place a neodymium magnet on top to make a button, and glue it also. Use good glue, just glue the edges of the button. These are my go to batteries day to day for battery fans (which use flat top) and my EDC light. They are just as good as a brand new LG HE2. I Even found a source for 3500 mAh LG battery for $7, to which I will have to add the magnet for my EDC light. What I can't get for love or less than a small fortune is a quality 14500 battery. I thought of using eneloop in my Lumintop EDC05 and may yet, but I think it's pointless to own an 800 lumen flashlight that only goes up to 320 lumens, so I will used the poor li ion batteries available and restrict full brightness to brief bursts. The 14500 batteries available to me are low drain and don't support more than 0.5 amp draw, fine for cheap 14500 china lights, not for a high powered light like Astrolux. Do your homework, might be some legitimate bargains out there like my LG Choco. I'm told that IKEA Ladda batteries are rebrand eneloop, but less expensive.
Hello, I need help, I bought a M3 pro flashlight from "On the Road" but it did not come with a battery and I don't know what battery to buy, I saw the Olight rcr123 but I am not sure it will work with this flashlight since there are 2 types of these batteries, one with a lighter green color and the other with a darker green, please help
Hi Matt. My gut as well as some forum resources say that I should be able to run batteries capable of much higher amp outputs than a given light requires with no risk of damage to the circuits. Are there any reasons you in your seemingly infinite wisdom can think of that would contradict that notion? I have had a couple (High quality brand name here) 1200lumen headlamps fail on me and I was told that it was because I ran a battery capable of an output of 10 a in them. That just never made sense to me. Thank you kind sir!! Be well
Yes that is basically correct. You can run a cell capable of high amp discharge in a lower powered light. Most high drain li-ion cells are UN-protected so you do have the risk of draining the cell too low that could damage the battery. The only way that using a high drain cell could damage a light is if the light was direct drive. A high capacity cell will have higher internal resistance so it will drive the LED at a lower current. 99% of lights that are direct drive are made with high current cells in mind though. What headlamp failed?
That's ok to use 14500 3.7 800mah lion,and normal 1 AA battery in bushnell flisglit won't damage the battery.or (bushnell 2 AA batteries flashlight.ok to and use in this one one cheese and one EBL 14500 .3.7 lion)thanks
Hy! Nice chanel. I am subscribed now. I have a question: i have a flashlight with 4 AA 2450 ni mh cells ( nitecore ha40) . Please tell me if the nitecore hc33 witch run with one 18650 ,3600 mah cell will light longer than the 4AA cells flashlight. Is it worth it to buy a new light with 18650 cell over my flashlight with 4xAA eneloop cells? Thank you!
Hi Vanessa. An easy way you can get an idea of which setup would give more run time is to convert to watts. Your NIMH AA cells are 2450ma (or 2.45 amp) at 1.2V and you have 4 of them so 2.45a x 1.2v= 2.94 watts per cell x 4 cells = 11.76 watts total. The 18650 is 3.7V x 3.6 amps = 13.32 watts total. So there is a slight gain in capacity. There are other factors to consider, but if all other things are equal, for example if your light runs at the same current using the 3.7V cell as it does with 4AA etc.
Damn dude. You teach, really, what needs to be known. Even I didn’t know that 18650 is the literal measurement of the battery. And I’ve been using them for years now

Thanks for this basic info. People often forget when learning something new that you need need to start with basics.
Clear,concise and educational - a must watch for the novice.
Thank you for informing us without a long intro, corny jokes and no loud UA-camr-tone of talking. And no useless sponsor mentioning.
Agree, except sponsor mentioning, that is not fair to them, IF it is their sponsor as long as it does not skew the content, useless to you not them. It is not all about you or I. It is their living so cut a little slack.
Yup, Matt is the most honest guy on UA-cam amongst all the cancer and I certainly appreciate it, refreshing and reminiscent of old UA-cam.
Such an important video for anyone utilizing these cells, I see tons of vapers with zero knowledge of batteries who will continue to run them with rips in the wraps. This is among the many reasons we have venting and explosion horror stories in the media. This should be required viewing.

Thanks for this video sir! Made it really easy to follow.
Excellent and very helpful video & information. Thanks
Excellent and informative video, thanks for sharing. 👍🏻
Fantastic video man...
Great vid. Brilliant advice. Ty.
Great video, I also use the Efest and Keeppower, but also use Panasonic, Samsung, and LG.

Can l just ask why you are not a big fan of protected batteries? Thanks
i subbed and thank you for explaining i wish you made another lesson video it really helps me learn
Your video is very informative thank you...
Nice intro video for someone getting into the hobby.
Thanks Jon.
OUTSTANDING commentary and educational. I enjoy your webcast. 🔦🐢🔦🐢🔦🐢

Thanks, great video.
Any 18650 that claims to be more than 3400mah is most likely lying there is a limit to the power to size factor.
Thanks for that tip. Really sucks the scammers doing this.
Exactly! Like UltraFire.
At the absolute most 3600. And those are so much more expensive than 3000-ish cells, they're usually not worth it.
Lg makes some I trust them
Just like the Flashlight companies exaggerating Lumen output! But hey, everyone is a liar.
Thanks for great information. 👍

I have a flashlight with 6 AA battery what would be a good alternative
Been wondering what charger I'd need for a 18650, need a battery or 2 and battery but not sure where to buy or what to get
I have a Acebeam K70 I’m wondering what battery you would run in it?!
The last digit in Li-ion batteries numbers refers to the package shape. 0 means it's a cylinder.
Hey Tom. Thanks for letting us know :)
It's messed up that a 65mm cell doesn't need to be 65mm long. Cram the extra circuitry *inside* the 65mm.
So are Panasonic/Sanyo NCR batteries basically ICRs, or similar to that? Can’t seem to figure that out.
Hi i have got samsung 30q 18650 batteries 3.7v batteries and i have been having problems with them the first one i bought stopped being recognised by the charger and now i have one that when fully charged only reads 3.3 volts.

I never let anyone bring me a battery even though I was charging it on a homemade rig I never had a problem like that again .
What does NCR mean? Is that like ICR (risky/cobalt)? Can NCRs release harmful fumes (HF poisoning, etc)? Very helpful video btw. Thanks
NCR stands for "Nickel / Cobalt / Rechargeable" which designates it as a hybrid lithium-ion rechargeable battery. That type are used in electric vehicles, , electric bikes, power tools etc. but if you have say a Panasonic NCR18650B or the like, it can only handle around 4.9 amps CDR (constant discharge rate) so check the specs on your flashlight as you wouldn't want to use them in a high output/high drain light that's going to be pulling a lot of amps.
AtPro411 Thanks, very helpful. I have a few 18650s that are Sanyo NCR18650GA 3500mAh 10A. Have always wondered if these are as safe as IMR and INR chemistries. Sounds like they aren’t. Maybe safer than ICRs though?
hi matt can you use vaping 18650 high drain in torches that are 35A? got some samsung 25R but dont know if they will do the job
Hi Matt, love your videos and your enthusiasm! Can I replace a16 340 1300 milliamp hour 3.7 volt cheap Chinese battery with a comparable better battery preferably lithium. To be honest I don't know if this thing is lithium or not.
Try XTAR VP4 or Dragon Charger is the BOMB!!!
What is a good rechargeable 18650 battery
I have a Sanford SF438SL-2SC torch
Just the head
I don't know which battery to use
The manufacture I found saying 1900 mah 3.6 v ni-cad battery
I can't find it or even online buy it
Which li-ion battery can replace it
Hey Matt, I love your videos. How can I get in touch with you about modifying a convoy flashlight that I have?
I have to say that in 2014,I purchased a flashlight that came with 2 ultra fires and a charger. I charged them when I received them.Used the flashlight a few times before storing it in my glove compartment..2 months ago.(2020) I remembered the light was in there and KNEW it would be discharged.., Man the thing lit up like the sun and is still working for me with about once a week uses ..Charged in 2014..lol
I need your help, I have a surefire flashlight, uses 2-cr123 cell. I want to get a battery that will replace 1 rechargable high drain battery. Help
My question is if I get a light that takes 16340 can I use a cr123 instead?
Matt, really enjoying the knowledge drops! Have you used Orbtronic batteries? Thoughts?
Are GP Recyko batteries good?
Oh and great vid.
So if I have a flashlight that takes two CRI 23 batteries I can replace them with two AA batteries ?
question, what would be the best brand of 18650 batteries? i have a acebeam k75 and want very good batteries for it for maximum use and performance.
Personally I like SonyVTC6 button tops for an unprotected cell. The keeppower 3120 ma cells are a protected version of this. The K75 carrier is designed for protected cells so either the acebeam 3100ma or the keeppowers would be best. You can fit the unprotected cells if you stretched the springs.
I have a cheapy menards Guidesman 5w flashlight. I like it because if the flood and spot capabilities. Its bright. I look for addresses for work with the spot. Three questions.
Can i get a different battery or two, replacing the 6 aaa batteries it takes?
If not is there a better aaa battery than the EBL Nmh 1.2 v 1100 mAh? It seems it doesnt hold the charge all that long.
And Last
Is there a better slim profile not so long flashlight with spot to flood capabilities?
My guidesman is just a bit annoying with putting in my pockets because the bezzel or head of the flashlight is wider and bulky, its a bit uncomfortable when sitting so it comes out of my pocket. Need something less in length (6 inches i belive its at)
Thanks.
Is there a difference between CR 123 and CR 123a.
And what's the benefit of higher voltages, will the flashlight shine brighter?
I mean, if I got a Li ion 18650 to use in my flashlight instead of regular alkaline AAs, or even rechargeable Ni MH, would it be brighter?
Can I also assume that because of the larger size(of 18650s vs. AAs) that the batteries would last longer as well? Or does the size get "neutralized" because of the greater discharge/output amperage(if that's the right term)?
Using li-ion cells means that you get higher voltage but it also means the batteries can carry a heavier load (amperage). You should not try and put li-ion batteries into a device unless you know for sure it is made to handle it. In some AA size flashlights you can replace the cell with a 14500 size li-ion and it will be much brighter, but only if the driver board in the light is made to handle it. Otherwise you will burn it up.
@@Lumencraft- Thanks.
I actually have a flashlight that takes two AAs, and it's pretty bright, but the seller said it actually can take 18650 batteries as well, but I'm a bit unsure about that, often times sellers don't put the correct information in their ads.
Also, it's unfortunate that I cannot find a webpage for the company or product so I could check it out and get the info straight from the manufacturer.
i am also interested in NiCd batteries
This guy's cool...oh yeah, I've fallen for buying cheap 18650 batteries on ebay. I've never used them. I didn't know better at the time, but now that I do, I'm too nervous to try them.
Should I use nihm batteries of same rating and sizes but different brands, eg 800 gb and energizer
I bought 2 18650 cells that are supposedly used in e-ciggarettes and they say SE US18650VTC4 C4

Sometimes there is a reason batteries are cheap, like they are past their best by date. I am in the Philippines where we have plenty of blackouts. The best deal I have found lately is LG Choco 3000 mAh. The ones I buy are 19 months old and have lost some capacity, although never used. They are still 20A but are down to an honest 2600 mAh...but they only cost me $4 for two of them. My EDC light takes button top batteries so I place a neodymium magnet on top to make a button, and glue it also. Use good glue, just glue the edges of the button. These are my go to batteries day to day for battery fans (which use flat top) and my EDC light. They are just as good as a brand new LG HE2. I Even found a source for 3500 mAh LG battery for $7, to which I will have to add the magnet for my EDC light. What I can't get for love or less than a small fortune is a quality 14500 battery. I thought of using eneloop in my Lumintop EDC05 and may yet, but I think it's pointless to own an 800 lumen flashlight that only goes up to 320 lumens, so I will used the poor li ion batteries available and restrict full brightness to brief bursts. The 14500 batteries available to me are low drain and don't support more than 0.5 amp draw, fine for cheap 14500 china lights, not for a high powered light like Astrolux. Do your homework, might be some legitimate bargains out there like my LG Choco. I'm told that IKEA Ladda batteries are rebrand eneloop, but less expensive.
Hlo bro my bright light led battery about 6" total size cell missing please tell me how can I find voltage rating of battery for my torch
Hey Matt, we need to know who the reputable battery dealers are. Can you suggest a few?
Hello, I need help, I bought a M3 pro flashlight from "On the Road" but it did not come with a battery and I don't know what battery to buy, I saw the Olight rcr123 but I am not sure it will work with this flashlight since there are 2 types of these batteries, one with a lighter green color and the other with a darker green, please help
Get an 18350 it's much better than cr123
Ner Montiero thanks, but doesn't it have to be a 16340?
Is 26650A same with 26650?
Hi Matt. My gut as well as some forum resources say that I should be able to run batteries capable of much higher amp outputs than a given light requires with no risk of damage to the circuits. Are there any reasons you in your seemingly infinite wisdom can think of that would contradict that notion? I have had a couple (High quality brand name here) 1200lumen headlamps fail on me and I was told that it was because I ran a battery capable of an output of 10 a in them. That just never made sense to me. Thank you kind sir!! Be well
Yes that is basically correct. You can run a cell capable of high amp discharge in a lower powered light. Most high drain li-ion cells are UN-protected so you do have the risk of draining the cell too low that could damage the battery. The only way that using a high drain cell could damage a light is if the light was direct drive. A high capacity cell will have higher internal resistance so it will drive the LED at a lower current. 99% of lights that are direct drive are made with high current cells in mind though. What headlamp failed?
@@Lumencraft- I have lost 3 ArmyTech Wizard Pro headlamps. the last gen 1050 lumen units. I have never had failures like that in hundreds of lights.
That's ok to use 14500 3.7 800mah lion,and normal 1 AA battery in bushnell flisglit won't damage the battery.or (bushnell 2 AA batteries flashlight.ok to and use in this one one cheese and one EBL 14500 .3.7 lion)thanks
I cannot find proper battery for my GT micro I have thought 14500 batteries they don't power it fully do you know where I can get proper batteries
Lithium battery tortch or li -on battery is good... Pls answer
I will have to try the immedion
Hy! Nice chanel. I am subscribed now. I have a question: i have a flashlight with 4 AA 2450 ni mh cells ( nitecore ha40) . Please tell me if the nitecore hc33 witch run with one 18650 ,3600 mah cell will light longer than the 4AA cells flashlight. Is it worth it to buy a new light with 18650 cell over my flashlight with 4xAA eneloop cells? Thank you!
Hi Vanessa. An easy way you can get an idea of which setup would give more run time is to convert to watts. Your NIMH AA cells are 2450ma (or 2.45 amp) at 1.2V and you have 4 of them so 2.45a x 1.2v= 2.94 watts per cell x 4 cells = 11.76 watts total. The 18650 is 3.7V x 3.6 amps = 13.32 watts total. So there is a slight gain in capacity.
There are other factors to consider, but if all other things are equal, for example if your light runs at the same current using the 3.7V cell as it does with 4AA etc.
AdventureSportFlashlights Thank you so much! Amazing answer. Respect and i will watch your future videos.
Who else held their breath at 1:10 ?
Yes! :D But knew this guy wouldnt do it.
fredadhbit
What, why? Are you saying if he actually touched the calipers to both the poles the battery could discharge and potentially do harm?
@@mydogskips2 it certainly would, and in spectacular fashion.
i paused the video and came searching to see if anyone else noticed. whew.
