ampere-hour

Charge storage measure

An ampere-hour is a unit measuring electric charge—the quantity of electricity transferred by one ampere of current flowing for one hour.

It's the standard way to express battery capacity: a 100 ampere-hour battery.

Abbreviated Ah or amp-hr.

A milliampere-hour (mAh) rates smaller batteries like those in phones.
