Surefire SF18650B 18650 Lithium-Ion Rechargeable Battery 3.6V 3,500 mAh - Red/Black

The Surefire SF18650B is a high-performance 18650 lithium-ion rechargeable battery engineered for demanding Surefire weapon lights and flashlights. Rated at 3.6 volts with a generous 3,500 mAh capacity, this protected cell delivers extended runtime and reliable output for high-output illumination tools.

A built-in micro-USB charging port eliminates the need for a separate charging cradle - simply plug any standard USB cable into the battery to top it off from virtually any USB power source. An integrated LED indicator glows red while charging and switches to green when fully charged, so status is always clear at a glance. A typical full recharge takes roughly 8 hours.

Certified to CE / PSE / UN38.3 standards, the SF18650B pairs built-in protection circuitry with Surefire's strict quality control and a rated 8-10A discharge. This single pack includes the SF18650B battery and a micro-USB charging cable, ready to keep your compatible Surefire light powered and ready to go.
