Kit includes two LFP 123A lithium-phosphate rechargeable batteries and a combination wall (AC) and car (DC) charger with appropriate AC and DC cables. These batteries-which retain approximately 50% of their original capacity even after 500 charging cycles-will power SureFire illumination tools that use disposable 123A lithium batteries. The charger, which features a charge status indicator light, will charge two LFP 123A lithium-phosphate batteries simultaneously. The runtime of these LFP 123A batteries is approximately 50% less than the runtime provided by disposable 123A lithium batteries; maximum output levels are typically not affected. Use of these rechargeable batteries can result in a cost savings over time, depending on usage habits.
Warning: As with disposable 123A lithium batteries, do not mix rechargeable LFP 123A lithium-phosphate batteries with other types or brands of batteries, including but not limited to 123A lithium batteries.
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."
