Outstanding First Experience With this Cell Type
June 28, 2016
I did an awful lot of research before buying these cells. When it comes down to it the IMR chemistry is safer than standard NiMH or other rechargeable chemistries. Man do these things pack a punch! Thus far these cells are punching well above their 800mah rating.
ProsSurprisingly well priced. More capacity than they are rated at. Provide a nice even power stream.
ConsSome devices do not take IMR chemistry.

Using in Nitecore EC11
September 16, 2019
Nitecore recommends IMR 18350 for the EC11. The EC11 can use 16340 or CR123 but needs 18350 for full brightness. These are low-priced and have good reviews. Performance is very good, purchased 2.

For use in my MT10C
April 5, 2017
I purchased these along with a Nitecore MT10C. Usually use lights that take CR123's so this was a good fit. I bought the rechargeables to get the max brightness from the light. Not disappointed. Have recharged the two I purchased twice so far and not a single problem. If they last a few years, I will not have any complaints. I also thought the price was reasonable.

High Output, Possible Low Reliability
April 26, 2016
I ordered two of these in August 2015. After about 8 months of use and maybe 10 recharge cycles each, one of the two batteries I received no longer holds a charge. I use these in my Nitecore MT10C and EC11, which will take IMR 18350's.
ProsHigh output.
ConsLow reliability - one of two failed after about 8 months and 10 recharge cycles.
