A battery charger and method for charging a battery are provided. The method includes comparing a battery temperature with an environmental temperature, charging the battery in a normal charge state if the battery temperature is greater than the environmental temperature and charging the battery in a warm charge state if the battery temperature is not greater than the environmental temperature. The method further includes monitoring a difference between the battery temperature and the environmental temperature when charging in the warm charge state, and switching from the warm charge state to the normal charge state when the difference between the battery temperature and the environmental temperature is within a predetermined range.
