| Amp-hours (AH or Ah) are the units of accumulated or cycled charge. It’s the same type of measurement as coulombs. This is a quantity of “stuff,” but it’s not “used up,” it just moves around in a circuit. We also talk about battery capacity in terms of amp-hours (though using watt-hours would make life easier). There is no such thing as “amps per hour” in normal electrical life—don’t say it! | |
