1. A charger device for charging one or more batteries of a vehicle, wherein
the charger device is operable in different user selectable modes including a power mode and an economy mode,
in the economy mode, during a time interval that is determined based on a user selected time, the charger device:
monitors an alternating current (AC) line input voltage, and
charges the one or more batteries with a first charging current that varies according to a variation in the monitored AC line input voltage,
the charger device is operable in one of the different user selectable modes until a battery threshold voltage is reached, and
when the battery threshold is reached, the charger device performs constant voltage charging of the one or more batteries until a second charging current for constant voltage charging attained is less than a set threshold current value.
