INTRODUCTION
The Auto Charge 11DV Battery Charger is a compact completely automatic charger
designed for installation on vehicles with two batteries. An internal charge divider charges
both batteries simultaneously while maintaining battery isolation. Remote sensing permits
long lines between the charger and the batteries by compensating for the voltage drop in the
charging wires. An ammeter provides continuous indication of the charger output. Input
power may be either 115 volts or 230 volts . A voltage selector switch is provided on the end
panel near the output terminal strip.
Construction of the Auto Charge 11 is extremely rugged to withstand the shock and vibration
normally encountered by vehicle mounted equipment. The unit operates completely
automatically and stops charging the batteries when they are fully charged. There is no
trickle charge and therefore no danger of overcharging and water boil-off. Any parasitic
loads on the battery such as radio, lights, etc., are automatically supplied with current by the
charger.
INSTALLATION
The Auto Charge 11 Automatic Battery Charger should be installed in an area with adequate
ventilation. A power cord is supplied for connection to 115 or 230 volts 60 Hz.
1. Mount the charger using the four holes provided for this.
2. Connect the wiring from the batteries to the Output Terminal Strip. Spade lugs that
have been securely crimped, or soldered, should be used.
3. Connect the wiring to the batteries. Ring lugs that have been securely crimped, or
soldered, should be used.
4. Double check all wiring before proceeding.
5. Wire the A.C. power line cord to 115 or 230 volts.
6. Pilot light will light to show that the charger has power.
