Abstract
A battery charger which senses the percent of charge in a battery, selects automatically on a continuous basis a constant output charging voltage by switching between two different taps of a transformer, limiting the output voltage not to exceed 17.5 volts to protect the electronic components of the vehicle having the battery therein, against the adverse effects resulting from overcharging and compensating for changes in temperature to maintain a constant level of voltage in continuously charging a battery to the point of being fully charged.
