The Streamlight SL-B34 rechargeable battery is a lithium-ion power cell designed to keep your Streamlight tactical and duty flashlights charged and ready in the field. With 3500mAh capacity at 3.6 volts, this battery delivers consistent runtime for demanding users—whether you're on patrol, working a night shift, or running training drills. The SL-B34 integrates USB-C charging, so you can top off your battery from any modern power source without fussing with proprietary chargers or docking stations.
Built-in safety circuitry guards against the overcharge and over-discharge damage that can kill lithium-ion batteries prematurely, extending the pack's service life. This means fewer replacements and more reliability when you need it. If you run a Streamlight MegaStream USB or another compatible Streamlight model, the SL-B34 is a drop-in replacement that takes seconds to swap.
This single-pack includes one SL-B34 battery. For users who rotate between multiple flashlights or want a spare on standby, picking up an extra pack ensures you're never caught with a dead light.
