may or may not have vent caps. Vent caps are located on top of the bat-
tery and provide a means to add distilled water when needed. Batteries
should be marked with their type. If charging a battery that is not marked,
check the manual of the item that uses the battery.
CHARGE RATE BUTTON 13.3
Use this button to set the maximum charge rate to one of the following:
2A SLOW CHARGE RATE:• Intended for charging small batteries such as
those commonly used in garden tractors, snow mobiles and motorcycles.
The 2A rate is not intended to be used as a trickle charger for larger bat-
teries.
12A• FAST and 30A RAPID CHARGE RATE: Use for charging automo-
tive, marine, and deep cycle batteries. Not intended for industrial applica-
tions.
80A START: • Provides 80 amps for cranking an engine with a weak or run
down battery. Always use in combination with a battery.
NOTE: To turn OFF the charger, unplug the power cord from the wall
outlet.
USING THE BUILT-IN VOLT METER TO TEST BATTERY STATE OF 14.
CHARGE
OVERVIEW
This battery charger has a built-in volt meter to test your battery’s state
of charge. The charger does not have a built in load tester. As such, a
recently charged battery could have a temporarily high voltage due to
what is known as “surface charge.” The voltage of such a battery will
gradually drop during the period immediately after the charging system is
disengaged. Consequently, the tester could display inconsistent values for
such a battery. For a more accurate reading, the surface charge should be
removed by temporarily creating a load on the battery, such as by turning
on lights or other accessories.
TESTING SEQUENCE14.1 : There are four basic steps required to test the
battery state of charge:
Connect the charger battery clamps to the battery. 1.
Connect the charger power cord to a 120V AC 2-prong wall outlet. 2.
If necessary, press the 3. BATTERY TYPE button until the correct type is
indicated.
Read the voltage on the digital display or press the display mode but-4.
ton to set the tester to BATTERY % to read the voltage as a percent of
charge.
