1. A battery charger, comprising:

  • a relay that controls the flow of an electrical charge current from a power supply to one or more batteries;

    a control unit that controls the actuation of the relay; and

    a temperature sensor that continuously measures the ambient temperature of the one or more batteries and communicates the temperature measurements to the control unit;

    wherein the control unit receives the temperature measurements from the temperature sensor, determines a charging time period for the one or more batteries, and selectively actuates the relay for the charging time period; and

    wherein the charging time period for the one or more batteries has a predetermined duration and represents a coolest time period within a monitoring period of the control unit.
