This charger is equipped with
Automatic On-Off Technology. After
connecting to a 12 volt battery, the
charger needs to sense a minimum
voltage condition to begin charging
and it will stop charging when it
reaches the maximum voltage
condition, but it will continue to
monitor the battery charge level.
The charger will "hum" as it monitors.
If the battery charge level drops, the
charger will begin charging again.
Note: If the charger does not sense a
minimum voltage condition
because of a deeply
discharged battery, then
preactivation of the battery is
required (see the following
paragraph PREACTIVATION
OF A DISCHARGED
BATTERY). The meter will
read zero or near zero.
Step 1:
Make Connections
Make sure AC power cord is
unplugged from wall outlet. Make
proper connections to the battery as
explained on pages 4–5.
Step 2:
Select Battery
(Switch 1)
Select the NORMAL/ AUTOMOTIVE
position to charge automotive
batteries and deep cycle batteries that
are older than two years.
Select DEEP CYCLE for marine
batteries that are less than two
years old.
Step 3:
Select Function
(Switch 2)
Select the CHARGE position to
charge the battery. This is the
automatic mode for 12 volt batteries.
Select the START position if you are
attempting to start a car with a weak
battery or to preactivate a
discharged battery.
Step 4:
Select Setting
(Switch 3)
Select the 100 AMP START position if
you are attempting to start a car with
a weak battery (12V only). Plug the
AC power cord into the wall outlet.
Note: For best results, charge the
battery first for 10 to 20
minutes using the 15 A, 12 V
position before attempting to
start the vehicle in the 100
AMP START position.
Engage the starter for 3 to 4 seconds;
if engine fails to start, charge the
battery using the 15 A, 12 V position
for another 10 to 20 minutes and
attempt to start the engine again. Be
aware that a typical starter on a
vehicle may need 250 to 500 amps to
start the engine.
Select the 15 A ,12 V AUTO position if
you are charging large lead acid
batteries, such as those used in
automobiles, boats, trucks, vans, farm
equipment, etc. Plug the AC power
cord into the wall outlet. The meter will
read up to 15 amps and taper down to
6 or 7 as the battery reaches full
charge. When the battery is fully
charged the charge complete light will
come on, the meter will drop to 0
amps, and the charger will
automatically stop charging.
