Introduction
The AUTO CHARGE 35/10 is a compact, completely automatic, single channel
battery charger designed for vehicles with a single battery system. The charger is
ruggedized to withstand the shock and vibration encountered by vehicle mounted
equipment.
The battery charger features:
• Electronic remote sensing of true battery voltages, eliminates the need
for sensing wires
• Automatic current limiting
• Built-in BATTERY SAVER
• Remote bar graph battery charge/condition indicator
• Power “ON” LED indicator
• BATTERY SAVER overload indicator
Charge Controls & Electronic Remote Sensing
The Auto Charge 35/10 contains a precision voltage controller to maintain the
battery’s charge. Automatic electronic remote sensing measures the true battery
voltage, eliminating the need for the additional sense wires. The output current of
any charger is inherently a series of pulses whose frequency is determined by the
power line frequency. Therefore there are brief intervals during which no charging
current flows. During this brief interval the Auto Charge 35/10 measures and stores
the battery voltage. This battery voltage is compared to a standard and any error is
detected and used to control the charger output at the desired level. Their is no
“trickle charge” and therefore no danger of overcharging and water boil-off.

Automatic Current Limiting
When batteries are severely discharged, some battery chargers can be overloaded
due to the high charging current required. The Auto Charge 35/10 contains an
automatic current limit. This circuit limits the output current to the rated 35 amperes
when charging a deeply discharged battery or if the starter cranks the engine while
charging. The current limiter thus eliminates the need for an ignition interlock
circuit.
Battery Saver & Indicator
A 10 ampere BATTERY SAVER is built into the charger. When connected as
shown in the installation wiring diagram, loads on the battery 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 10 amperes.
WHEN A BATTERY SAVER OVERLOAD OCCURS:
a. Remove the loads for approximately two minutes
b. Reduce the load to 10 amperes or less
c. Reapply the load to the BATTERY SAVER
No fuses are required or provided as the BATTERY SAVER contains an automatic
circuit breaker.

CAUTION
This battery saver output is a full wave
rectified sine wave. The 12.5 volts D.C.
has a peak value of approximately 17.5
volts.
It is recommended that the loads are not
highly capacitive. A large capacitor on
the load terminal will "peak detect" the
output and create a voltage of
apporximately 17 volts. This voltage ma y
be too high for the component connected.
It is suggested that the installed check
the output of the battery saver (when
operating with A.C. input) and determine
as each load is connected that the voltage does not rise. Any load that creates
an increase in voltage should not be
connected to the battery saver but rather
be connected directly to the batter y.

Remote Battery Charge Condition Indicator
This remote indicator shows the charge condition of the 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 discharged 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 the battery when the A.C. power is “OFF”.
