A method of charging lead acid batteries is provided. The method includes, in order, the steps of: a) applying a first applied voltage to a battery until the open terminal voltage of the battery exceeds a first target voltage, and then disconnecting the first applied voltage, b) applying no charging voltage to the battery for a time exceeding 30 seconds, and monitoring the open terminal voltage of the battery until the voltage falls below a second target voltage, c) connecting a second applied voltage lower than the first applied voltage to the battery until the battery reaches a second target voltage lower than the first target voltage, d) connecting a third applied voltage lower than the second applied voltage to the battery for an extended period of time. An apparatus for performing the method is also provided.
