Read this entire manual before using your charger. The tips below serve only as a
guide for specific situations.
CHARGING TIPS
Reviving your battery: If you only wish
to charge your battery enough to
operate your vehicle; you don’t need to
wait for the entire charging process to
be completed. When the charger
displays a battery % of 77 or more (see
page 14), the battery has usually been
charged enough for the vehicle to start
and operate normally.
KNOW YOUR CHARGER
Read this entire manual before using your charger. The items below are additional
features of your charger.
Relay: Your charger is equipped with a
relay. This device turns the charge
current on and off to the battery. It is
normal to occasionally hear a clicking
sound when the relay is turned on or off.
Fan: Your charger is equipped with a
fan. It is normal for the fan to be on
while the charger is charging (as long
as the voltage is above 9V). The fan is
normally off at other times but may cycle
on and off due to temperature or other
conditions (See Overtemperature
Protection). Keep the area near the
charger clear of obstructions to allow
the fan to operate efficiently.
Overtemperature Protection: Your
charger is equipped with an internal
thermocouple. This device monitors the
temperature and allows the charger to
turn the fan on and off as needed. If the
temperature rises above a preset level,
the charge current will be reduced to
allow the charger to cool. If the tempera-
ture can not be reduced at the lower
charge rate, the charge current will be
turned off until the temperature is
reduced to a normal level. The charger
will then continue where it left off. For
best results, do not place the charger in
direct sunlight or enclosed spaces with
high temperatures.
Completing an interrupted charge: If
the charging process has been
interrupted and restarted after the
charger displays a battery % of 85 or
more, the charger could go straight to
Maintain Mode (see previous page).
However, if the original charge was
started using 12A, the charge can often
be completed using the 2A rate.
MAINTENANCE AND CARE
A minimal amount of care can keep your battery charger working properly for years.
1. Clean the clamps each time you are finished charging. Wipe off any battery fluid
that may have come in contact with the clamps to prevent corrosion.
2. Coil the input and output cords neatly when storing the charger. This will help
prevent accidental damage to the cords and charger.
3. Occasional cleaning of the case of the charger with a soft cloth will keep the finish
shiny and help prevent corrosion.
4. Store the battery charger in a clean and dry location.
