This Streamlight SL-B34 lithium battery is a replacement power source for compatible Streamlight lights, sold as a single pack. Lithium cells are a popular choice for duty, home-defense, and outdoor lights because they hold a charge on the shelf for years and deliver steady output in cold weather, where alkaline batteries tend to fade. Keeping a spare in your range bag or vehicle kit means your light is ready when you need it. Streamlight is one of the most trusted names in tactical and professional lighting, so using their own battery packs helps maintain the performance and fit the light was designed for. Check your light's manual to confirm compatibility.
