Abstract
The voltage of a unit for recharging an accumulator battery is reduced to a low level when the battery is in a charged state as determined by a predetermined fall in the trickle charging current. When the charged state of the battery is no longer maintained as determined by a fall in battery voltage below the low voltage level and a predetermined increase in trickle charging current, the voltage of the unit changes to a high level.
