Frequently Asked Questions

Do all 20v power tool batteries work with all brands of power tools?

Most power tool batteries are not compatible with power tools of a different brand. However, most power tools within that brand tend to use the same battery. For example, most Dewalt 20V power tools use the same battery. The same goes for Craftsman, Ryobi, etc.

What do amp hours mean?

Amp-hours are often abbreviated as Ah, and they refer to the length of time a battery can produce one amp of power per hour. They loosely refer to battery life, though it doesn’t necessarily mean that a 5 Ah battery will last for five hours. However, a higher amp hour rating is certainly better than a low one.
