What is the difference between rated capacity and typical capacity?
Rated Capacity. Rated capacity is the maximum amount of energy that a battery can store when it''s fully charged. It''s the number that manufacturers use to advertise their batteries, and it''s usually listed in ampere-hours (Ah) or milliampere-hours (mAh). For example, a 2000mAh battery has a rated capacity of 2000 milliampere-hours.
Battery Capacity
The storage capacity of the battery is also expressed in watt hours or Wh. If V is the battery voltage, then the energy storage capacity of the battery can be Ah × V = watt hour. For example, a nominal 12 V, 150 Ah battery has an energy storage capacity of (12 ⁎ 150)/1000 = 1.8 kWh.
