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.

- 13. Apparatus for charging batteries comprising a body inside which an electric and electronic component is housed for supplying a charging current to a battery, a supply cable for connecting the apparatus to an electrical supply grid, connecting cables for connecting the apparatus, directly or indirectly, to a battery, wherein said apparatus comprises a LED member that is suitable for indicating an operating status of the apparatus, said LED member comprising 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.
- 20. Method for charging a battery by means of an apparatus for charging batteries comprising a first battery heating and desulphation step, a second constant current charging step and a third constant voltage charging step, wherein in said first step the battery is supplied with current pulses having a maximum value that is lower than the maximum value of the charging current in said 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.
