Charge-discharge efficiency

WebIn this case, the discharge rate is given by the battery capacity (in Ah) divided by the number of hours it takes to charge/discharge the battery. For example, a battery capacity of 500 Ah that is theoretically discharged to its cut-off voltage in 20 hours will have a discharge rate of 500 Ah/20 h = 25 A. Furthermore, if the battery is a 12V ... WebWh (watt-hours) efficiency tests of UltraBattery in a stationary application for an electricity smart grid showed that over 30 cycles of charge-discharge at rates of 0.1 C10A, Wh efficiencies ranged from 91% to 94.5%, depending on the battery's state of charge.
