Abstract
A cyclic battery charger reduces the formation of the ionic barrier in a battery. The battery charger applies a current to the battery for a first period of time. To reduce the ionic barrier, a discharge current is applied to the battery for a second period of time. The charging current and discharging current are applied cyclically to the battery during the entire charging period. The discharge current may be applied by the battery charger, or may be the result of the current drawn from the powered device. The discharge current may be a fraction of the charging current, and is applied to the battery for only a limited time during the charging cycle as compared to the charging current.
