This battery lasts seemingly forever. I charge it, which takes an hour or two, and the battery lasts for many trips to the airsoft indoor field. I have gone through many many many many non-rechargeable CR123a baatteries and I regret not getting these earlier. This company makes nice, affordable rechargeable (and also non-rechargeable) batteries.
