A battery charger includes an irregular power source, a capacitor connected to the power source for storing charge from the power source, and a control circuit which is operable to detect a charge current of a battery to be charged and to discharge the charge from the capacitor into the battery when the charge in the capacitor reaches a predetermined level. The control circuit is configured to change the predetermined level from a bulk charge mode to a float charge mode when the charge current is at or below a threshold value. |
