Is the Ryobi PGC21B worth it?

Yes if you need a spare or a step up from a 1.5Ah kit battery. It costs less than Ryobi's larger packs and doubles runtime in most drills and drivers.

Will it fit my Ryobi tools?

It fits any Ryobi One+ 18V tool and charger. It will not work in 40V or 12V tools.

How long does the 3.0Ah battery last per charge?

Expect roughly twice the runtime of a 1.5Ah pack in the same tool. High-draw tools like circular saws will drain it faster.

What is the difference between this and an HP battery?

HP packs use higher-current cells that give more power in brushless HP tools. The PGC21B is a standard pack and works fine in ordinary One+ tools.

The battery only. No charger is included.

Ryobi battery packs often drop during holiday sales and kit promotions. Watch the price history for dips below the typical street price.

Our take on the Ryobi PGC21B Battery

The Ryobi PGC21B is a 3.0Ah 18V lithium-ion battery for Ryobi's One+ cordless tool line. It fits every One+ 18V tool and charger, so it works as a spare or an upgrade for the compact 1.5Ah packs that ship in kits. The 3.0Ah cells roughly double the runtime of a 1.5Ah pack in the same tool. It is a standard-capacity pack, not one of Ryobi's high-performance HP batteries, and it carries a one-year warranty rather than the longer coverage on some Ryobi packs.
