Batteries for Discontinued Lights

These batteries are designed for specific ASP light models that have been discontinued. Availability may be limited. To ensure compatibility, performance, and safety, please use the Battery Reference Guide below, and make sure to order the battery that matches the one you are replacing or supplementing. If you no longer have a battery to compare, use the chart to find your light model and order the battery that is designed for it. Older ASP batteries may not be compatible with current-model flashlights, and are not compatible with non-ASP lights. To purchase batteries for current-model ASP lights (models with "C" designation after the name), click here. ASP Lithium-Ion rechargeable batteries are built for reliable performance and long service life in high-output flashlights. Designed for high-drain use, they feature integrated Protection Circuit Modules (PCM) to help prevent overcharging and over-discharging. Most versions feature onboard charge ports, either Micro USB or USB-C allowing the battery to be charged directly with a standard portable electronics cord.
