SureFire Rechargeable Battery Kit for LED Flashlights
SureFire has released a Rechargeable Battery Kit for their LED Flashlights, dubbed the SF2R-KIT01. The kit includes two rechargeable LFP 123A lithium-phosphate batteries and a charger. The batteries will work with any SureFire LED light that uses disposable 123A lithium batteries. They will hold roughly 50% of their original capacity even after 500 charging cycles. The charger can use an AC (wall socket) or DC (car) to recharge the LFP batteries, and charges two batteries at a time.
There is a downside though, as with pretty much all rechargeable batteries the LFP 123A’s run time isn’t anywhere near as long as disposables. Compared to SureFire’s disposable 123A lithium batteries the LFP’s have approximately 50% the run time. Also these batteries are only to be used in SureFire lights that use an LED emitter, they are NOT to be used with lights with incandescent bulbs.
MSRP for the SF2R-KIT01 is $29, and additional LFP 123A lithium-phosphate batteries (SF2R-CB) are sold in pairs for $12.
