20V Universal Batteries

Packs built for the generic 20V slide mount rather than one brand's proprietary connector. They fit tools sold under WORX, Ryobi and several house brands, which is the point: one battery covers a mixed drawer instead of three. Voltage stays at 18V nominal, so a tool rated 20V MAX runs normally.

Check the mount before you buy. Universal 20V is a physical standard, not a promise that every 20V tool accepts it, and a pack that will not click in is a pack that sits in a drawer. Compare the rail shape on your existing battery against the listing photo. Capacity claims on this shelf run unusually high, so check whether the milliamp-hour figure is quoted at the cell level or at the pack level.

The 10000mAh to 20000mAh range covers the capacity spread. Our universal 20V picks compare the packs side by side. Can you mix brands explains where cross-brand use is safe, and running a DeWalt pack in a Makita tool covers the adapter route.
