The SF18650B is a Lithium Ion-protected 18650 battery with MICRO-USB charge capability, allowing convenient charging using any USB power source such as a USB wall charger, computer/laptop, power bank, or automotive USB port with the included MICRO-USB to USB cable. This high-performance 3.7V 18650 lithium-ion rechargeable battery features two LED indicators that display the current charge state: Red for charging and Green for fully charged.
The battery provides 3.6V of output power with a capacity of 3500mAh, resulting in a 12.6Wh energy consumption rate to power high-drain devices like LED flashlights for up to ten hours. An external 18650 compatible CC-CV cradle charger (not included) can be used to charge the battery; possibly at a faster rate if so equipped. The SF18650B is compatible with the following SureFire products: BSL-A Ballistic Shield Light, FURY-DFT, EDC2-DFT, FURY-IB-DF, M600DF, M640DF, M640DFT and P1R series.
