About this product
Batteries are platform-level investments in the 18V tool world: one pack feeds five or six bare tools, so buying right once pays for the whole fleet. The 6Ah capacity of BL1860 runs angle grinders and impact drills with more composure than the 3Ah packs. One confirmation is unavoidable in this product line: the word Original in a listing title doesn't necessarily mean genuine, and third-party compatible packs are abundant at this price with widely varying quality. Ask the seller whether it's genuine, or treat it explicitly as a compatible pack — compatible works too, but know what you're buying. Also check your tools' battery interface generation: 18V LXT and XGT don't interchange.
