CR123A Rechargable Battery Review
December 27, 2014
Great battery, a pair work perfectly in my Tovatec LED underwater torch. Stay away from the Efest 850mAH as 1 battery protection circuit blew every time in the torch. They must have a low draw current. But these now problems. Run time is about 35 minutes in my torch, as compared to standard CR123A batteries which last about 3 times as long.
High draw current so does not trip the protection circuit and make the battery useless
Run time could be longer

Great rechargeable batteries!
November 20, 2014
I use these batteries in 4 different flashlights, as well as in two stun guns, and their performance is excellent. They re-charge many times, and hold their charges for a very long time. They are far better than Nimh batteries in terms of their performance and life span.
Plenty of power, and long life span.
None that I am aware of.

Be careful what you use these in
November 11, 2014
I purchased the combo charger and four battery set from BJ. Two of the batteries came charged to about 3.5v and the other two were completely discharged upon arrival. So I charged those two with the supplied charger. When checked with a meter, the two I charged topped out at 4v, give or take a tenth. I just got the set, so I've only used one of the batteries, one of the 4v ones, in an Olight S10 Baton, which accepts RCRs of higher voltage. I've used it on the high setting for quite a few minutes a day for three days in searching out moths in the apartment, and it's still only discharged down to 3.55v. In the "Features" description on the product page it says, "Replace the most of CR123A primary Lithium battery for a digital cameras and most flashlights." Accounting for the poor grammar, I assume it means it's safe to use these in 3.0v CR123A applications. DON'T BELIEVE IT. You could easily ruin your device by over-voltage. I'm going to run the current battery down to 3.2v or less before trying it in a standard CR123A device (Fenix PD22.) And I've also experienced the problem of inconsistent fit in the flashlight barrel, but not too badly so far. I hope to give an update after I've tried a few more over time.
Charge much higher than stated in description. Could ruin a device.

Excellent, reliable high capacity battery - Battery Junction Superb Order Experience!
November 7, 2014
I have used these batteries for years in my premium flashlights. They charge quickly and HOLD their charge even 6 months in a drawer! (though I charge/cycle them every three months but on more than one occasion, have skipped a cycle and still had a great charge. I ordered 10 more of these batteries just to have on-hand. During San Diego's 4hr power outage, they kept us well lit!
Fast charge, long shelf life, excellent for any application using CR123 batteries. I highly recommend them as a product and once again, my thanks for fulfilling my order so promptly. A great battery at an equally great price.

Tenergy 30201 RCR123A 3.0V (3.2V) 900mAh Rechargeable Li-Ion
July 6, 2014
I use them in SUREFIRE-HS2-A-BK, I've found that rechargeable batteries have a side strip that make them fatter. Peeling off the top plastic coat / label there is a second plastic coat that keeps that strip in place. SureFire Minimus is a tight fit and so far I've found this is the best rechargeable for this flashlight. I've had 3 of these batteries that quit charging and would make the flashlight start to blink right after so called charging. I find that to make it through a 10 hour work shift, it's wise to have 6 of these available if you charge at home. They last 1.25-1.5hrs on high 100Lm. Longer on a lower setting. I tried to do the same with the Nitecore, but it has a thick side strap and no secondary plastic wrapper to hold the battery together and the Nitecore has plastic ends that separate. Like anything, some last long and some fail within a few weeks or few months and some just keep going and going. So those who write a bad review got that one that failed. But for the most part, I'm happy with it because of those that didn't fail. So don't just buy one.
Fits in SureFire Minimus once label is removed.
Bought 2 then found I needed 4 more = 6 and over a year use had 3 of the 6 fail. Not necessarily the oldest failing to keep a charge. Thus buying more replacement batteries. Turned bad ones over to hazmat.

The work like recharble batteries should!
April 19, 2014
I bought an LED flashlight at a truck stop that came with 2 CR123 batteries. The problem was the cost over regular batteries. I looked online and learned about rechargeable CR123 batteries. I had rechargeable batteries before and have never liked them. However these are lithium batteries and the chemistry is much better than NiMh batteries. These batteries are incredible. They have a built-in chip that regulates the voltage, so the power output is very linear and when they've reached in of their power output they just switch off. I like this feature because I don't like flashlights that continually dim during use because of regular batteries. These Tenergy Re-chargable batteries 900 MAh So the run time is very good and as of to this day they still have the same runtime after 7 years of moderate use. The charger I got for them is very nice and has an LED light, red for charging and green for finished. The charger charges 2 batteries at a time. The charger is powered by house current or a 12 Volt receptacle in the car. I take this flashlight everywhere I go. I use it in hotel rooms to see where I'm going when I get up in the middle of the night. I travel a lot and don't know my way around each different floor plan and have found it just easier to use the flash light. I use this flashlight and the Tenergy RCR123 batteries for night training operations in the desert. I am very sure that I have saved a lot of money over the years. Since using the rechargeable lithium ion batteries I do not like using AA ,AAA or D and other non-lithium batteries anymore. I love Lithium ion rechargeable batteries they worked exactly as I've always fantasize rechargeable batteries operating.
Light weight, powerful and 900mah. Owned them since 2007 and they still work great giving good service after each charge. Working as good now as they did in 2007. Once you Go lithium you never go back.

Works fine in my thermal sight
December 15, 2013
I use mine in a UTAC-32M thermal sight (it takes 2 123A\'s). Depending upon screen brightness, they run my thermal sight 1.5 to 2.0 hours (non chargeable CR123A 1550mAh run it 4-5 hours). I let them \"settle down\" in voltage for an hour after charging and then use them. For my use, they sure save money, as I was going through 4 non rechargeable CR123A\'s per night of hunting.

these batteries suck, they go into protection in less than 30 seconds in my Olight mx-20 they also flatten the ends so they no longer make good contact, thats just from bouncing around in normal use not rough duty or even heavy duty. One set was much better than the other but niether was reliable enough for any use let alone first responders.

After comparing these to the AW cell I purchases to replace these, I can tell you there is no comparison. Go for a better battery.

Not for high drain apps.
May 29, 2013
I agree with Peter on this one. I purchased 3 sets to use in a quark pro and I get about 20 mins of runtime before the batteries start going into protection. They have lasted at least a couple hundred cycles so far though. These may be good for some applications with low drain but a high drain light is too much for these little guys. Just bought some AW cells. I\'ll update this with a comparison in a few weeks

Quick to enter protection mode
June 4, 2012
I\'ve cycled mine a few times now, and they are getting better, but they are quick to enter protection in high draw. If your light fits an 18650, use one of them versus two of these.
