Why This Tool Is Worth It

Batteries are usually the most expensive part of any cordless system. Getting two 4.0Ah packs plus a charger for under $80 changes the math on every RIDGID bare tool you buy later.

These MAX Output batteries deliver more power and longer runtime than RIDGID’s 1.5Ah packs. They also work with every RIDGID 18V tool, so nothing you already own gets left out.
