Charge. Win. Repeat.
The SureFire SFLFP123 rechargeable batteries provide a reusable power option for customers who prefer rechargeable 123A-format cells in compatible SureFire illumination tools, including LED flashlights, WeaponLights and hands-free lights.
The cells use lithium iron phosphate technology, also known as LiFePO4 or LFP, and contain no hazardous heavy metals. Although their runtime is significantly shorter than that of disposable SureFire 123A lithium primary batteries, they are safe, cost-effective and retain approximately 80% of their original capacity after hundreds of charging cycles.
Two package options are available. The standard SFLFP123 set includes two rechargeable cells only. The SFLFP123-KIT includes two cells, a two-bay smart charger and a Micro-USB-to-USB-A charging cable.
The included smart charger can charge one or two cells in approximately 1.5 to 3 hours. Internal circuitry automatically terminates the charging cycle when the batteries reach full capacity and provides protection against overcharging, short circuits and reverse polarity.

Compatibility and Safety Note
The SFLFP123 batteries are intended only for compatible LED illumination products designed to operate with disposable 123A lithium batteries.
Do not use SFLFP123 batteries in illumination tools equipped with incandescent lamps. Their elevated initial voltage may damage or burn out an incandescent lamp filament.
Do not mix rechargeable SFLFP123 cells with disposable 123A batteries. Fully charge all rechargeable cells before installing multiple batteries in the same illumination tool.
