I recently upgraded my workshop tools and picked up a for my cordless drill and impact driver. I was impressed by how lightweight it feels compared to older NiCd batteries, yet it packs enough power to handle heavy-duty projects. The battery holds a solid charge and fits perfectly in all my Craftsman 19.2V tools without any wobble. I also noticed the smart design with built-in protection circuits keeps the battery safe from overcharging or overheating. For anyone still using older packs, switching to this 19.2 volt Craftsman battery is a noticeable upgrade in performance and reliability.
