Auto Charge 4000, w/ Dual Bar Graph Display
Cat. No. 091-89-12

The Auto Charge 4000 is a high output dual battery charger that independently charges two banks of batteries. Unique electronic sensing circuits senses the true battery voltage while eliminating the need for external sense wires. Charging is completely automatic. The maximum output of the charger is 40 amperes. The entire 40 amperes may be supplied to one battery or it may be divided between the two batteries. The lower charged battery is favored to receive more of the charge. When the two batteries are equally charged the charge is divided equally. When the batteries are fully charged, all charging stops. There is no overcharging and no water boil off.

A common problem with electrical systems is the loading on the battery caused by rechargeable hand lights, portable radios and other loads. The Auto Charge 4000 handles these loads with a built-in "BATTERY SAVER". Auxiliary electrical loads are connected to the "BATTERY SAVER" output. During normal vehicle operation these auxiliary loads are connected to battery #1. When the vehicle is plugged in to A.C. power, the auxiliary loads are automatically removed from the battery and powered from the "BATTERY SAVER" circuit. A maximum of 5 amperes is available from the "BATTERY SAVER". An automatic overload protector limits the 5 ampere output. A yellow overload indicator is illuminated whenever the "BATTERY SAVER" output limit is exceeded.
