1. A battery charger circuit controlling the safe charging of a lead acid storage battery, having in combination,a transformer embodied in a battery charger circuitry,means in said circuitry producing a DC charging voltage for a battery,said transformer having a high tap and a low tap,a voltage sensing means signals for a shifting from said high tap of said transformer to said low tap of said transformer when the charging voltage reaches 17.45 volts and signals for a shifting from the low tap to the high tap when the voltage is below 13.6 volts,means sensing the temperature at said battery, andmeans varying the charging voltage to compensate for temperature increases and temperatures decreases.
