kAh
kiloampere-hour
Electric chargeexact by definition
The kiloampere-hour is the charge delivered by one thousand amperes for one hour, exactly 3.6 megacoulombs. Utility and telecom battery strings, submarine batteries and large stationary storage banks are rated at this scale. The conversion is exact, both the ampere and the hour being exactly defined.
Watch out: As with any ampere-hour figure, this is charge and not energy. A 1 kAh string at 48 V holds 48 kWh, and the same 1 kAh at 400 V holds 400 kWh, so nameplate charge is only comparable within one system voltage.
