INTRODUCTION
The AUTO CHARGE 2000 is a compact, completely automatic, dual channel
battery charger designed for vehicles with two batteries. The charger is rugge-
dized to withstand the shock and vibration encountered by vehicle mounted
equipment.TheAutoCharge2000PumpPlusoperatesan091-9aircompressor.Withthe
selector switch in the AC position the compressor runs only when the AC power is applied.

Plus automatically recharging the batteries as required.
The battery charger features:
• Independent charge controls for each battery
• Electronic remote sensing of true battery voltages, eliminates the need
for sensing wires
• Automatic current limiting and apportionment
• Built-in BATTERY SAVER
• Remote dual battery charge/condition indicator
• Power “ON” LED indicator
• BATTERY SAVER overload indicator
DESCRIPTION
Independent Charge Controls & Electronic Remote Sensing
The charger contains two independent charge controls, one for each battery.
This allows each battery to be independently charged while maintaining battery
isolation. Each battery voltage is remotely sensed, electronically, eliminating the
need for four sense wires. Each of the charge controls is completely automatic and
stops charging the battery when it is fully charged. There is no trickle charge and
therefore no danger of overcharging and water boil-off.
Automatic Current Limiting & Apportionment
The charger contains automatic current limiting at 15 amperes. This is a total
current limit for the two batteries combined. The charger automatically apportions
the current to each battery. Either battery can draw the total 15 amperes. When
charging unequally charged batteries, the lower charged battery receives a higher
charge rate. When the batteries are equal, the current is shared equally until they
are fully charged at which time the current goes to zero.

Battery Saver & Indicator
A 3 ampere BATTERY SAVER is built into the charger. When connected as
shown in the installation wiring diagram, loads on battery #1 such as radios and
rechargeable hand lights are automatically switched to the BATTERY SAVER
when power is applied to the charger. The BATTERY SAVER allows more efficient
charging by removing these loads. A BATTERY SAVER overload indicator alerts
the operator that the BATTERY SAVER load has exceeded 3 amperes.
WHEN A BATTERY SAVER OVERLOAD OCCURS:
a. Remove the loads for approximately two minutes
b. Reduce the load to 3 amperes or less
c. Reapply the load to the BATTERY SAVER
No fuses are required or provided as the BATTERY SAVER contains an electronic
overload interrupter.
Remote Dual Battery Charge Condition Indicator
This remote indicator shows the charge condition of each battery in 10 levels
from “LOW CHARGE” to “FULLY CHARGED”. This device indicates a defective
battery when a bar graph does not rise to the “FULLY CHARGED” level after an
extended period of charging.
NOTE: If a battery is being charged with an external load of 1.5 to 4 amperes
across it’s terminals, the bar graph may move down 1 or 2 levels. This
does not indicate a defective battery.
To avoid this, connect all external loads to the BATTERY SAVER
terminals.
Loads connected to the BATTERY SAVER will be powered either from
the BATTERY SAVER power supply when the A.C. power is “ON”, or
they will be connected to battery #1 when the A.C. power is “OFF”.
