power up

Solid battery for the money
July 22, 2020
I purchased a couple of these a while back for an Olight Triton that is not often used and the batteries work well, holding a charge over time. Holding a charge over time (self discharge) seems to be the problem with these rechargeable 18650 batteries. I have purchased this same exact battery from another vendor (that was a mistake so please order from battery junction because they have great customer service and nice people in general) and the ones purchased from 'vendor b' have problems holding a charge so when I grab my light its dead. So either this brand is counterfeit from other sellers (I have read in a few forums that is likely the case) or is subject to bad batches. So buy these from here knowing customer service will take care of you if you need it.

great battery for the price

I ordered a laser from a Chinese company and it took 3-1/2 months to get and it arrived without a battery. Of Course Battery Junction was right there with the unique battery I needed at a great price.
