Rechargeable Flashlight and Lantern Batteries

Lithium rechargeable batteries are the preferred power choice for high powered flashlights, camp lanterns and battery packs.

About Rechargeable Lithium Ion Batteries

Lithium rechargeable batteries offer specific energies higher than NiMh batteries making them the preferred power choice of high powered flashlights, camp lanterns and battery packs. Lithium batteries perform well in cold weather conditions, do not exhibit memory effects, have low self discharge rates (they can be stored for years and still retain power) and charge rapidly. We offer CR123 lithium, and 18650 and 26650 lithium-ion cells.
