Abstract
An improved battery charging method is usable by a battery charger to charge a battery. The charging method may include an optional desulfation process, a first constant current process, a constant voltage process, a second constant current process and a float charge process. The charging method preferably improves various charge and usage characteristics of the battery through a single or continued use of the battery charger utilizing the charging method.
