CHARGER FOR RECHARGEABLE BATTERIES

摘要

A battery charger ( 1 ) for charging rechargeable batteries ( 5 ) and/or battery packs is disclosed. Preferably the charger ( 1 ) can apply two modes of charging a battery. In a normal charging mode a battery is charged to full capacity at a relatively low rate. In a boost charging mode the battery is charged very rapidly and only to maximally 80% of its full capacity. The boost-charging mode makes it possible to provide some charge to the battery ( 5 ) when the time available for charging is limited. Due to the partial charging a much higher charging current than allowed at normal charging may be applied during boost charging.
