Abstract
An apparatus and a method for charging a battery are disclosed. The apparatus includes a LED member that includes a single LED that is suitable for emitting light of different colours, each colour corresponding to a different operating status of the apparatus, and an acoustic signalling device that is suitable for emitting an acoustic signal indicating a malfunction of the apparatus or the battery. The method includes a first battery heating and desulphation step during which the battery is supplied with current pulses having a maximum value that is considerably lower than the maximum value of the charging current in a subsequent second constant current charging step, each current pulse being generated when the current absorbed by the battery after the delivery of a previous current pulse falls below a minimum preset value.
