ASP Lithium-Ion rechargeable batteries are custom-fabricated to provide increased energy density and longer life. Our 18650 battery is optimized for use in high-drain devices such as our performance flashlights and features a Protection Circuit Module (PCM)—an important safety feature that guards against overcharging or over-discharging.

Our latest generation of Lithium-Ion batteries features an integrated micro USB charge port. This means that in addition to in-light recharging (with compatible ASP flashlights), the battery can be charged on its own, simply by plugging a micro USB cord directly into the cell. The 18650 includes a Link Case, to safely store, protect and transport the battery. It features an interlocking design that allows multiple Link Cases to be connected to one another for efficient organization.
