At 8.0Ah, each battery stores twice the energy of a 4.0Ah pack and four times that of a 2.0Ah pack — ideal for high-drain tools like circular saws and reciprocating saws. With two batteries in rotation — one in the tool, one on the charger — you can work continuously without waiting for a recharge.\u003c\/p\u003e\n\u003ch3\u003eFrequently Asked Questions\u003c\/h3\u003e\n\u003ch4\u003eWhich Ridgid battery part numbers do these replace?\u003c\/h4\u003e\n\u003cp\u003eThey are direct replacements for Ridgid R840083, R840085, R840086, R840087, R840088, R840089, and the AC840085, AC840087, and AC840087P series.
