Abstract
A battery charger is provided for industrial storage batteries which includes both digital and analog control circuits for controlling the charging voltage to maintain a charging cycle in which the current is initially held to a maximum value until the cell voltage rises to a preset level, after which the cell voltage is maintained constant at this level until a preset minimum current is reached, and the minimum current is then maintained for a fixed period of time. The charger requires no adjustments for ampere-hour rating or for number of cells in the battery, and is capable of charging batteries of any ampere-hour rating over a wide range, without any adjustment.
