A battery charger is provided which supplies pulses of charging current to a battery and discharges the battery between each charging pulse. The change in the battery terminal voltage over a predetermined period during each charging pulse is measured and the pulse charging is terminated when a parameter of the measured voltage change exhibits a predetermined characteristic. Pulse charging may be terminated as a result of the measured voltage change exceeding a predetermined threshold or as a result of the detection of a point of inflexion in the variation of measured voltage change with time.
