Another device that commonly uses CR123 that you might not think about - portable AED machines. The Zoll AED Plus unit has *10* of these batteries in it.
Thanks. Great video. I've tried explaining this same thing so several people but you explain it better than I can. This is important information for those new to CR123 batteries.
Cool vid. I use a lot of CR123, I buy them at the local gun shops that sell Surefire lights, they seem to sell the batteries for the best prices to encourage people to buy the lights
Hi, Like the examples you have shown. They have helped me sort out in my mind what I need. Just a note, I have a memory problem so having the batteries laid out like this is very helpful.
These tips that are said in the video are all great and correct. One thing is that you shouldn't throw them in the trash, it is recommended to recycle them at a facility. They contain Lithium which is fairly value, this reflects in the cost. Read On For More Information! I work over at Batteries + Bulbs. (Formally Batteries Plus) These are all rounded up to nearest dollar. 1 - $8.00 - $8.00/Battery 2 - $15.00 - $7.50/Battery 6 - $19.00 (Only select stores) - $3.17/Battery 12 - $27.00 - $2.25/Battery The brands we carry are Rayovac (1 Pack,2 Pack, 6 Pack), Duracell (1 Pack, 2 Pack), and Streamlight (12 Pack). Yes, mixing both used and new batteries can be very dangerous, possibly fatal. Same as with mixing different brands. If you need to know anything battery specific feel free to message me!
That maratac light that uses the AA is the most practical. In a pinch you can find an AA battery in a tv remote or out of a radio and the light works pretty good even on partially drained AA's. And you can use it as instant on by pressing the end with your thumb, without turning it. And it is plenty small. I love the shiny polished stainless too.
John Olivarez That depends on how many triggers and how long you set the video to be. And the setting of the battery management. I have 3 cameras since 4 months. One camera needed new batteries recently. I have tried rechargeables, but I haven't found any good ones yet. The current one have lasted 3-4 days at most. You do know that the latest model has rechargeables? As well as sound and quicker response-time.
Thank your for posting this video. I really appreciate your effort to warn us. Thank you for being so PATIENT. You Rock Dude! Thanks for ALL the GREAT posting you put up on the internet!!!
I have been using Surefire CR123 batteries in my Fenix PD30 for a long time now. No problems at all. Batteries last a long time with the type of EDC use I do so the cost is not really that bad. Just pick up a box of cells and use em up over time. They last a long time so no worries there.
you are so right about everything having the possibility of danger when misused. hell, even q-tips say right on the box "do not insert in to ear canal"
The SF's CR123 seem to be just a little bit longer than other brands CR123 so I think it's a good idea to check if they fit in the flashlight before you buy one.
I remember on Man v Wilid, Bear Grylls talks about if your phone is dead you can use your litium battery from it to puncture it and when it gets exposed to the air it'll ignite and burn and he shows you and actually starts a fire that way. So also good to know.
When my girlfriend's step father passed, he left us his massive surefire torch collection and until then, I'd never even seen a CR123A battery. He had stocked up on SF brand batteries that, unfortunately, don't seem to hold up to what their shelf life is stated to be. I was getting far less than 30 minutes of use from both single and double cell torches when I finally decided to toss them all about 2 weeks ago. After seeing this video, I'm glad I did. I never knew he had such an expensive hobby and collection, though. It's nuts.
@airsoftgunsandknives I never had intentions of owning a sage , but was offered one in trade I coudlnt resist because of the trade off, you asked about the light before I owned one
To quote another CZcams user, "Dangerous Things Are Good." Know what you're doing before you do without knowing. Good general list of reminders for users, Jeff.
@xDEMONIZEDx there is far more energy in the CR123 lithiums than say a standard alkaline AA, the transfer of energy in multi cell lights when you mix one new batterey and one used will overheat them to the point of explosion, somethgin that WONT happen in alkalines
Why don't the CR123a batteries I got from work fit my gunlight and small maglight style pocket light I have? They seem to wide. They don't fit in the tube. Don't the CR123's and the CR123a's have the same diameter and length?
@Zigosity an alkaline or NiMH battery might ooze out, they will not explode and or vent with flame and the gas is not nearly as poisonous if ingested, people have gone to the hospital having breathing issues after having one vent, its serious
for cr123 flashlights, its good to have rechargeable batteries. I bought a box of 12 surefire cr123 batteries for emergencies but i use the rechargeable batteries for everyday use
@RYDERkN and affordable compared to similar output lights from surefire but surefire cant compete with fenix/ 4 sevens because surefure is an american company, prices reflect that...but yes fenix TK40 630 lumens for 1 hour on 8 AA's...just remember with lights you cant have all three...you usaly get 2 out of three, the three are size, brightness and run time...the TK40 takes 8 batteries and is huge....and has a short run time on high
I see your point Jeff, I personally like the more powerful batteries. But let's say you have 3 Flashlights and you need 3 different batteries - if you run out on one of the six options, 1 light is gone, and batteries can't be shared. What I like to see is that AA and AAA batteries get better and used more in devices, so the supplies can be shared. I'm even bothered by the fact that my Fenix E01 uses AAA and my Fenix LD10 uses AA batteries and that I cannot share in an emergency situation.
Hey Jeff you should try AW's IMR16340 cells in the lights that'll handle 8.4V, it's Lithium Manganese chemistry which is a rechargeable lithium ion, but it has zero chance of explosion/venting in flames, it also can provide upto a 8C constant discharge, eg 1 16340 size LiMn cell can provide upto 4A of current, that's enough to power a SST-50 at full power and a XM-L at full power, the downside is the low capacity which is 550mAh.
You forgot to mention that cr123 shelf life is 10 years and pwns alkaline shelf life. I have used "Tenergy" brand from amazon.com cr123 batteries in conjunction with dealextreme's various single celled flashlight models with no issues. Came in handy when trick or treating last year, the throw on these lights are insane it was like a mini sunrise in my hand.
Just curious never got a straight answer for this, is it okay to leave 2 CR123A lithium in flashlight? Will the flashlight drain over time? I have a sure fire set up to pressure switch. Should I just put them away next time I decide to use flashlight?
I have a night vision monocular that runs on cr123 batteries. The interesting thing is that cr2 batteries work too. Will these be less powerful? Or what will the downside be to using these?
My store sells the Surefire and Streamlight branded CR123 batteries for $1.99 a piece or $21 for a dozen. Sounds kinda pricey but that's literally the cheapest price you can find them around me for about 100 miles.
i like your how you try and explain stuff, the aaa and the aa are the same battery just different shape ie but they are both 1.5v,, but the cr123a is a different shape but they are 3v twice the voltage, so for every cr123a you have it,s 2 x aaa or aa i wish cr123 would becmome more popular
Crap man. In the beginning of the vid, I was like, "ha, what a pansy. Batteries scared him away." As you went further in, not I'M skeptical of my cr123 batteries! I recently bought some rechargeable on ebay and was wondering why I only got about half an hour out of my lights. NOW I KNOW! I ALMOST DIED MAN! YOU SAVED MY LIFE! THANKS!
Hi Cutlery lover would you recharge a cr123 battery, I stopped using my scorpion flashlight because if the expence, in fact just a few hour's ago I pulled my scorpion out it was in a box with other flashlights, I'm not a high tech guy, and I really like my mag flasklights, but you can't argue how much better the light is on my scorpion, maybe I just use my scorpion too much, because it seems the batteries go real fast for me, could it be something wrong with the flashlight that causes it to drain the batteries so fast, Thanx in advance.
man ive been using cr123 in my surefire light for 4 years with no problems at all and the batteries are not expensive. i buy surefire brand batteries at lowes. pack of 2 for $4.50
I just found my 3 brand new a123 batteries from 2010 in a storage bag I had put away, I put them on a charger and they charged up quick. The only problem is I need a flashlight that is compatible
I always carry two flashlights, and both use the 123 batteries. The ones I avoid are AAA's since getting them in lithium is nearly impossible and very expensive.
I must admit, Imma CR123 fan. They blow away all other batteries. I may have missed this in the vid, but they also have an excellent shelf life - about 10 years. I think they'd be great to put into a storm shelter for that reason alone. Also, maybe it's cause I've already done my homework, but a lot of this information seemed quite obvious. But I suppose for a complete noob it's good info to know.
What do you think about rechargeable cr123's in flashlights and if you like or dislike them what brand would you buy or what is a good brand I'm new to cr123's so i would like to know what you think. Thanks do much
When batteries go dead in one light, I like to take them and suck them dry in my single cell lights, is this bad?(Any possibility of damage). Also, what point should I stop using CR123 batteries in the multi cell light, when the light doesnt turn on anymore or when it starts to dim? I have a Maelstrom S18 and only use new batteries from 47.
Two other points about the CR123's: They are not weather sensitive. So when it's cold...it does not effect the life of the battery. They die when they run out of energy. Unlike typical batteries...they will not dim and fade then slowy die. CR123's use up all there energy and continue to give you max output until it's completely out of energy.
@xDEMONIZEDx True, I have 2400mAh 11.1V lithiums for RC planes and when those go wrong you better hava fire extinguisher. Its not the safety factor I have a problem with its just that they aren't readily available.
Read up everything you can on rechargeable rcr123's and get a couple of good quality cells. Batteries will never be a problem again. I'm using an AW RCR123 in my 4sevens Quark 123 Tactical.
Kind of late and don't see a reply but yes as he stated the same holds true for laptop and cellphone batteries. Anything lithium based. Lithium-ion or lithium polymer, including the AAA lithiums.
uhmmmm just so you know you put the CR123that was out ( not sure if you used it or not )into the box just in case since you were talking about how it not good to mix
hey jeff, are these saftey warnings for just cr 123s or all lithium batteries i.e. like a AAA lithium battery? trying to upgrade my battery usage from regular old cheap alkoline but just wanna be safe
@divineconscience none of these lights have a output high enough to need a heat sink temporarily putting it face down on high on will do nothing at all to the led
i have a 4sevens 123^2 tactical r5 edition and it takes 2 cr123's i use energizer litiums. usually buy 2 pack at store for $10. i am going to buy a bunch in bulk from batteryjunction because $5 each battery is too much.
ion lithiumis the most efficient battery out there. That has my vote,though we're still not using them for more practical industrial uses i.e. cars,machines,etc.
@BuffaloWarrior7 A lithium 9volt has more potential than a lithium CR123. 9v at 1200mAh vs 3v at 900mAh the 9volt has more power potential. Anything with acidic chemistry is going to be potentially dangerous. If you drop your flashlight with normal Alkalines in it the conductors could potentially touch if the battery suffers any sort of trauma. Your battery could rupture in this situation and spill out battery acid which is dangerous.
I only have one flashlight that came with my Victorinox SAK, its a really nice little flashlight, runs off of two AAA batteries and it brighter than the 20-30 dollar lights my parents buy xD
Another device that commonly uses CR123 that you might not think about - portable AED machines. The Zoll AED Plus unit has *10* of these batteries in it.
Thanks. Great video. I've tried explaining this same thing so several people but you explain it better than I can. This is important information for those new to CR123 batteries.
That warning really makes a good case for getting Countycomms battery holder.

I'm just getting into this topic and can't thank you enough for how informative this great primer has been. Thanks man.
Hi,
Like the examples you have shown. They have helped me sort out in my mind what I need. Just a note, I have a memory problem so having the batteries laid out like this is very helpful.
"I don't like CR123 batteries!"
Has an entire box of CR123 batteries.

This video should be viewed by most people. The Arlo surveillance system use these type of batteries.
TheRobertSt I just got Arlo. what is the average battery life per camera? Do you know?
John Olivarez That depends on how many triggers and how long you set the video to be. And the setting of the battery management. I have 3 cameras since 4 months. One camera needed new batteries recently. I have tried rechargeables, but I haven't found any good ones yet. The current one have lasted 3-4 days at most.

@Nreckless all the batteries in the box have no been used including the one I use for the demo

Why call flashlight a torch?
@@slickbackgoonbythesaltylag30 If you can't answer that question through the process of thinking, you've got far bigger concerns, mate.
i have the xml edition of the mini 123 too. bought part of the first run. loving it, great light.
@gsxer13 you cna buy and use rechargable CR123's
@blackroses4her I had thought I specifically said surefire offerings, obviously other companies offer them in AA and AAA as I own them
i love my four sevens quark 123^2 tactical. the dual mode program is nice, i didnt like scrambling through the modes to get to where i wanted
@airsoftgunsandknives I never had intentions of owning a sage , but was offered one in trade I coudlnt resist because of the trade off, you asked about the light before I owned one
To quote another CZcams user, "Dangerous Things Are Good." Know what you're doing before you do without knowing.

Men I thought the same as you, and now re considering buying a CR123 flashlight for the same reasons that you mentioned
@TechCuber once you create a circuit they transfer energy sop both cells ahve equal amounts at all times and they drain evenaly
@Zigosity an alkaline or NiMH battery might ooze out, they will not explode and or vent with flame and the gas is not nearly as poisonous if ingested, people have gone to the hospital having breathing issues after having one vent, its serious
My Surefire x400 uses cr123 and I love it. It goes well on my Colt Rail Gun.
@jedininjapirate713 cheap isnt always good, please watch the video again
@guns4good surefire or any US company cant compete with other companies around the world either as our costs are much higher
@MrHickstopher $23.88 for a dozen or just $1.99 each from goinggear where I got a bunch of lights Ill be showing soon
for cr123 flashlights, its good to have rechargeable batteries. I bought a box of 12 surefire cr123 batteries for emergencies but i use the rechargeable batteries for everyday use
@simonsky8 great option, but if you need say 1000 lumens AAs wont cut it, haha unless your talking a half dizen or more and rechargable in a M@gmod
@RYDERkN and affordable compared to similar output lights from surefire but surefire cant compete with fenix/ 4 sevens because surefure is an american company, prices reflect that...but yes fenix TK40 630 lumens for 1 hour on 8 AA's...just remember with lights you cant have all three...you usaly get 2 out of three, the three are size, brightness and run time...the TK40 takes 8 batteries and is huge....and has a short run time on high

thanks alot im new to the flashlight hobby and its good information for me
I'm thinking about buying the E1B and would really like to see your review/ opinions on it before I spend my hard earned money. looking forward to it!
Jeff, these 'problems' with CR123As apply to ALL batteries. Any kind of battery could do this. It's intrinsic to the design of a battery.
@MsTechDude lol....uhhh yes, been using flashlights for years, like nice flashlights not dollar store lights
Awesome vid dude! Learned alot of tuff I didn't know,thanks!
Hi Cutlery lover would you recharge a cr123 battery, I stopped using my scorpion flashlight because if the expence, in fact just a few hour's ago I pulled my scorpion out it was in a box with other flashlights, I'm not a high tech guy, and I really like my mag flasklights, but you can't argue how much better the light is on my scorpion, maybe I just use my scorpion too much, because it seems the batteries go real fast for me, could it be something wrong with the flashlight that causes it to drain the batteries so fast, Thanx in advance.

hey i have a question, iv'e recharged my CR123s and its only gotten warn at most
but i'm hearing that you can't. how does it work so well for me
I must admit, Imma CR123 fan. They blow away all other batteries. I may have missed this in the vid, but they also have an excellent shelf life - about 10 years. I think they'd be great to put into a storm shelter for that reason alone.

REI sells a 12 pack for approx $2.40 each - $30 if you need something quick.
What do you think about rechargeable cr123's in flashlights and if you like or dislike them what brand would you buy or what is a good brand
I'm new to cr123's so i would like to know what you think. Thanks do much
When batteries go dead in one light, I like to take them and suck them dry in my single cell lights, is this bad?(Any possibility of damage). Also, what point should I stop using CR123 batteries in the multi cell light, when the light doesnt turn on anymore or when it starts to dim? I have a Maelstrom S18 and only use new batteries from 47.
man jeff your right that copper maratac light looks nice like that. i didnt think it would lok nice but damn!
Can you use a semi used CR123 cell in the quark mini, as it only uses one?
@RYDERkN my Quick, research shows 1 hour on turbo, but I may be wrong or at least my sources
Two other points about the CR123's:
They are not weather sensitive. So when it's cold...it does not effect the life of the battery.
They die when they run out of energy. Unlike typical batteries...they will not dim and fade then slowy die. CR123's use up all there energy and continue to give you max output until it's completely out of energy.
However, the USB rechargable Surefire keychain light he had ended up on my keyring and that thing is BRIGHT!! Holds a charge for months as well!
Would these same issues that plague the CR123 also affect the CR2 batteries?
Thank you for the video. 👍🏽
Are these the same size as LR1-N?
@xDEMONIZEDx True, I have 2400mAh 11.1V lithiums for RC planes and when those go wrong you better hava fire extinguisher. Its not the safety factor I have a problem with its just that they aren't readily available.
Most of your law enforcement supply stores sell them and they are reasonably priced.
@RuthlessZabusa Well in that case it was a simple misunderstanding. Sorry for any confusion.
Read up everything you can on rechargeable rcr123's and get a couple of good quality cells. Batteries will never be a problem again. I'm using an AW RCR123 in my 4sevens Quark 123 Tactical.
what are the best brand of CR123 batterys? im looking for longest lasting and lightest
Hmm... what if you use just a single CR123? Will the battery still be subject to the same energy transfer?
Kind of late and don't see a reply but yes as he stated the same holds true for laptop and cellphone batteries. Anything lithium based. Lithium-ion or lithium polymer, including the AAA lithiums.
uhmmmm just so you know you put the CR123that was out ( not sure if you used it or not )into the box just in case since you were talking about how it not good to mix
hey jeff, are these saftey warnings for just cr 123s or all lithium batteries i.e. like a AAA lithium battery? trying to upgrade my battery usage from regular old cheap alkoline but just wanna be safe
@divineconscience none of these lights have a output high enough to need a heat sink temporarily putting it face down on high on will do nothing at all to the led
Dang, seems like you need to be in a whole Hazmat suit! lol
what brands of cr123 batteries should I use
@charlesburton95 I didn't say misuse of a battery could make your weapon explode... I said if you use your weapon wrong it could explode...
i have a 4sevens 123^2 tactical r5 edition and it takes 2 cr123's
i use energizer litiums. usually buy 2 pack at store for $10. i am going to buy a bunch in bulk from batteryjunction because $5 each battery is too much.
You switched the positions of the SF cr123a batteries. Has it blown up yet?
what brand and what model is the 2nd flash light???
hey! cool you finally got a 4 sevens lights
great info Jeff, Thx and Blessings.
how long can i store a box of 12 surefire cr123 battery in my closet ?
@cutlerylover Do you think it would be bad to use rcr123 batteries in that 4sevens quark mini
ion lithiumis the most efficient battery out there. That has my vote,though we're still not using them for more practical industrial uses i.e. cars,machines,etc.
Thank you for the video. Solution= get a volt meter.
I am using Ultrafire 1300 lumens with two CR123A batteries but I already ordered the genuine Ultrafire 3000mah batteries
@BuffaloWarrior7 A lithium 9volt has more potential than a lithium CR123. 9v at 1200mAh vs 3v at 900mAh the 9volt has more power potential.

I only have one flashlight that came with my Victorinox SAK, its a really nice little flashlight, runs off of two AAA batteries and it brighter than the 20-30 dollar lights my parents buy xD
hey jeff, where can i buy maratac aaa with shipping to europe?
how much run time do you get out of a cr123?
