Streamlight SL-B9 Battery – 2 Pack

The Streamlight SL-B9 battery is designed for select Streamlight products. The battery features a built in USB-C ports and charge indicator.

The Streamlight SL-B9 Battery Pack consists of two rechargeable lithium‑ion cells specifically engineered for use in compatible Streamlight weapon lights and flashlights. Unlike traditional disposable CR123A batteries, the SL‑B9 cells feature an integrated USB‑C charging port on each battery, which means you can recharge them directly with a standard USB‑C cable without needing a separate charger. Each battery typically runs at around 3.6–3.7 volts with a capacity in the 800–900 mAh range, delivering reliable, consistent power for extended runtimes on popular models that accept the SL‑B9 form factor.

These batteries are built with internal protection circuits to guard against over‑charging, over‑discharging, and short circuits, helping extend both battery life and the life of your light. They’re especially appealing for everyday carry and duty use because they eliminate the recurring cost and waste of disposable cells; simply plug in with a USB‑C cable whenever needed and you’re ready to go. A two‑pack gives you a charged spare while one is in use, which is great for ensuring you always have power when you need it.
