IV. BATTERY SAVER
A 5 ampere Battery Saver is built into the charger. When connected as shown in the installation wiring
diagram, loads on the vehicle battery such as radios and rechargeable hand lights are automatically
switched to the Battery Saver when power is applied to the charger. The Battery Saverallows more
efficient charging by removing these loads. A Battery Saver overload indicator alerts the operator
that the Battery Saver load has exceeded 5 amperes.
WHEN A BATTERY SAVER OVERLOAD OCCURS:
a. Remove the loads for approximately two minutes
b. Reduce the load to 5 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.
V. BATTERY SAVER CAUTION
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 approximately 17 volts. This voltage may be too
high for the component connected.
It is suggested that the installer check the output of the battery saver (when operating with A.C. In-
put) 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 battery.
VI. REMOTE 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”.
