The biggest Ryobi battery isn't always the upgrade you think it is

The tool aisle rewards big numbers. Ryobi's 12.0Ah pack towers over everything else on the 18V ONE+ peg. When your compact keeps dying halfway through a job, grabbing the giant looks like the fix. It usually isn't. More amp-hours mean more runtime and nothing else. They add zero power to a tool that's straining, and Ryobi itself has pulled apart the tidy math between amp-hours and strength across its own packs.
