Rechargeable batteriesKeeppower RCR123A 800 mAh(16340) with protection (protected) is based on lithium ion technology. Li-ion technology gives one of the best ratios of the amount of stored energy to the weight of the cell. The batteries have no memory effect and self-discharge is minimal. Compared to standard Fenix RCR123A batteries, this cell has about 15% more capacity while maintaining the same dimensions, so the light time is also about 15% longer with this battery. We have verified the capacity by our own measurements.
