3.1
capacitive reactance
part of the internal resistance that leads to a voltage drop during the first seconds under load 3.2
capacity
electric charge (quantity of electricity) which a cell or battery can deliver under specified discharge conditions
Note 1 to entry: The SI unit for electric charge is the coulomb (1 C = 1 As) but, in practice, capacity is usually expressed in ampere hours (Ah).
3.3
fresh battery
undischarged battery 60 days maximum after date of manufacture
3.4
ohmic drop
part of the internal resistance that leads to a voltage drop immediately after switching the load on
