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.
Pros:Fits in SureFire Minimus once label is removed.
Cons: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.
