Ah Efficiency
Generally, the efficiency decreases with decreasing nominal voltage. It is assumed that similar capacity and similar internal resistance for cells of identical capacity results in similar absolute voltage drops during charging and discharging. If the voltage drop is 100 mV during charging and 100 mV during discharging and if η Ah of 100% is assumed, the efficiency, …
