Streamlight 20237 SL-B9 3.6V 850mAh Li-Ion USB-C Rechargeable Battery - 2-Pack

The Streamlight SL-B9 is a rechargeable 3.6V lithium-ion battery pack built as a USB-C rechargeable alternative to disposable CR123A cells in compatible Streamlight flashlights and weapon lights. This 2-pack keeps a spare ready so your light is never without power in the field.

Each SL-B9 cell delivers 850mAh (3.06Wh) of capacity through an integrated USB-C charge port built into the battery housing, so no separate charger is required. A full recharge takes approximately 2.5 hours, and the cell is rated for up to 300 recharge cycles. An on-board safety control circuit provides protection against overcharge, over-discharge, and short circuits.

Finished in a silver/black housing measuring just 1.36" long, the SL-B9 is the factory rechargeable battery option for Streamlight lights that accept the SL-B9 form factor. Two single-pack cells are included per purchase.
