ABSTRACT:
A battery charger control device which senses the placement of a battery across charging terminals and utilizes the voltage thereof to actuate a relay which turns on a battery charger, which utilizes a pulse generator to charge a capacitor over a period of several hours after the battery has been placed across the terminals, which monitors the charge condition of the battery as determined by the voltage across the terminals and which automatically and independently of the pulse generator applies charging current to the capacitor after the voltage across the terminals exceeds an adjustably preselected magnitude, and which utilizes the charge condition of the capacitor to turn off the battery charger after the lapse of a predetermined period of time or after the battery has become fully charged, whichever occurs first.
