The energy storage capacity of a battery will be rated in amp-hours (Ah). or watt-hours (Wh). 1 amp-hour is equal to 1 amp of current transferred during the course of an hour, which is the standard rating method used for lead acid batteries. In the PV sector it is becoming more common to rate batteries in watt-hours because it is easier to understand the total storage capacity of an energy storage system. To be able to compare the storage capacity of a system to the potential loads it is necessary to convert from amp-hours to watt-hours. The formula is simple:
