Streamlight SL-B9 3.6V 850mAh Li-Ion USB-C Rechargeable Battery Pack - 8 Pack

The Streamlight SL-B9 is a protected lithium-ion rechargeable battery pack built to power select Streamlight flashlights and rail-mounted weapon lights. This 8-pack gives you a ready supply of spare cells for duty belts, training rotations, or simply keeping several lights topped off at the bench or in the safe.

Each SL-B9 cell delivers 3.6V nominal voltage at an 850 mAh capacity and is rated for up to 300 recharge cycles. The integrated USB-C input with on-board safety control circuitry lets you top off a depleted pack in roughly 2.5 hours from any standard USB-C cable - no dedicated charger cradle required. A built-in charge-status indicator confirms when the cell is ready to go.

At just 1.36" long and 0.7 oz, the SL-B9 drops directly into compatible Streamlight lights as a factory replacement or upgrade battery. Streamlight backs the pack with a limited 2-year warranty.
