5 Cell NiCad Battery Pack. This is a Streamlight Original, not an aftermarket battery. This battery fits the Streamlight UltraStinger, Super Stinger and Streamlight SL-20XP LED flashlights. In time, even rechargeable batteries don't perform as well as they did when they were new. Streamlight offers battery sticks to restore your rechargeable flashlight to its factory new condition.
