nominal capacity

Nominal capacity:Nominal capacity refers to the amount of charge that a battery can store when it is fully charged. This value is typically expressed in milliamp hours (mAh). For example, a battery with a nominal capacity of 1000mAh can store 1000 milliamps of charge when it is fully charged. The nominal capacity of a battery may differ from its actual capacity, which is the amount of charge that the battery can store when it is new and has not been used before. The actual capacity of a battery will decrease over time as it experiences “charge cycles” (i.e., being charged and discharged).
