3. If necessary, press the BATTERY
TYPE button until the correct type is
indicated.
4. Read the voltage on the digital display.
Keep in mind that this reading is only
a battery voltage reading; a false
surface charge may mislead you.
Power-Up Idle Time Limit
If no button is pressed within 10 minutes
after the battery charger is first powered
up, the charger will automatically switch
from tester to charger if a battery is
connected. In that case, the charger will
be set to charge at the maintain mode
and gel cell battery type.
Testing After Charging
After the unit has been changed from
tester to charger (by selecting a charge
rate), it remains a charger. To change the
battery charger back to a tester, press the
CHARGE RATE button until all charge
rate LEDs are off.
Fan
The charger is designed to control its
cooling fan for efficient operation. It is
normal for the fan to start and stop when
maintaining a fully charged battery.
Keep the area near the charger free of
obstructions to allow the fan to operate
efficiently.
10. CALCULATING CHARGE TIME
BATTERY PERCENT AND CHARGE TIME
This charger adjusts the charging time in
order to charge the battery completely,
efficiently and safely. The microprocessor
automatically performs the necessary
functions. This section includes guidelines
that can be used to estimate charging
times. Use the following table to determine
the time it will take to bring a battery to full
charge. First, identify where your battery
fits into the chart.
CCA = Cold Cranking Amps
Ah = Amp Hour MO = Maintain Only
NR = Not Recommended
Find your battery’s rating on the following
chart, and note the charge time given for
each charger setting. The times given are
for batteries with a 50% charge prior to
recharging. Add more time for severely
discharged batteries.

11.4 Ensure that all of the charger components
are in place and in good working condition,
for example, the plastic boots on the
