BATTERY CHARGER AND SURVEILLANCE SYSTEM ABSTRACT OF THE DISCLOSURE A battery charging apparatus has a control circuit which controls the rate of input of AC power through a synchronous switch -- a saturable core reactor, magnetic amplifier or a pair of anti-parallel silicon controlled rectifiers. The operation of the charger is such that the length of the charging program can be predetermined,and when the charging program is initiated a survelliance system functions to determine that the charging current during the program, and particularly at the end of the program, is within anticipated limits. If the charging current is not within anticipated limits, an alarm indicator is latched on, giving the operator an indication of potential battery problems, and/or an indication of a battery/charger mismatch whereby one is over or under rated with respect to the other.
