Why This Tool Is Worth It

Running out of battery in the middle of a project is never fun. An extra pack keeps you working while the other one charges.

This MAX Output battery delivers up to 2X more power than the RIDGID 1.5Ah battery (AC870015), along with extended runtime.

It’s still compact, so it won’t weigh down drills, drivers, or other smaller tools. A built in fuel gauge shows how much power is left before you start a cut.
