Our take on the Porter-Cable 20V MAX 4.0Ah Lithium-Ion Battery

This is a two-pack of 4.0Ah lithium-ion batteries for Porter-Cable's 20V MAX cordless tools. The 4.0Ah capacity sits in the middle of the line: double the runtime of the common 2.0Ah packs, but heavier and shorter-running than the high-capacity 6.0Ah and larger packs. It fits every Porter-Cable 20V MAX tool and charger, so it works as a spare or a step up for tools that drain small packs fast. Owners rate it well overall, though a few report packs that stopped charging or died early.
