A method of charging a battery (50). The method comprises the step of supplying (101) an essentially constant charging current (C) of a predetermined first magnitude (C1) from a power source (10) to the battery (50), during a first constant current mode (CC1) of charging. Furthermore the method comprises the step of switching (102) to a second constant current mode (CC2) of charging when a battery voltage (Vb) reaches a predetermined threshold value (Vt1); and the step of supplying (103) an essentially constant charging current (C) of a predetermined second magnitude (C2) to the battery (B), during the second constant current mode (CC2) of charging. The second magnitude (C2) is lower than the first magnitude (C1). |
