ampere hour (Ah or amp hour) Part of the Smart grid glossary: An ampere hour (abbreviated Ah, or sometimes amp hour) is the amount of energy charge in a battery that will allow one ampere of current to flow for one hour. An ampere is a unit of measure of the rate of electron flow or current in an electrical conductor. One ampere of current represents one coulomb of electrical charge moving past a specific point in one second. A milliampere hour (mAh) is 1,000th of an Ah, and is commonly used as a measure of charge in notebook computer batteries. The mAh provides an indication of how long the PC will operate on its battery without having to recharge it.

Cordless Power Tool FAQ: What Does âAhâ Really Mean? Ah is an abbreviation for ampere-hour, or amp-hour. This the total amount of charge a battery can deliver in one hour. A power tool that continuously draws 1.0A of current will completely drain a 1.0 Ah battery pack in one hour (under ideal conditions). Obviously this means that a 2.0Ah battery pack can power the same tool longer than a 1.0Ah battery pack can, assuming the current flow remains at 1.0A and there are no other differences.

THE BATTERY Amp Hours (AH) - The volume of electricity, capacity. A battery’s storage capacity is measured in amps or amp (ampere) hours. One amp equals one hour of use without recharging-or, in practical terms, how long you can use power on a dark, rainy day.he equation for finding how many watt hours are available in a battery when the amp hours are known is voltage x amp hours. For instance, a 12 volt 105 amp hour (AH) battery can supply 1260 watt hours (12 volts x 105 amp hours =1260 watt hours).
