SureFire is now offering K2 Energy rechargeable LFP 123A batteries. They can be purchased alone or along with a wall/car charger. The runtime of these rechargeables is about 50% of disposable batteries but they do retain approximately 50% of their original capacity even after 500 charging cycles so over the long haul they can show substantial savings.
Please note – Rechargeable LFP 123A batteries are only to be used to power LED illumination products (built to use 123A lithium batteries) and NOT those featuring incandescent lamps. The initial elevated voltage of these rechargeable batteries, immediately after charging, may cause the filament contained within an incandescent lamp to break or “burn out”.
