Output selector controls
timer:
The Timer prevents over-
charging while allowing a battery the
needed time to obtain a satisfactory
charge. To set the Timer, you must know
the size of battery in ampere hours or
reserve capacity in minutes, and the state
of charge. Often the state of charge is not
known, which is why the Timer is limited
to 3 hours. With the aid of a battery load
tester (not included) the state of charge
can be obtained in a few seconds. For
example, the average size automotive
battery at 50% charge will require 1 to
1-1/2 hours of charging at 40 amp rate
to reach full charge state. For the same
battery with its Timer set to maximum, 3
hours of overcharging will occur. Slight
overcharging should not harm a battery
that was otherwise in good condition.
When the state of charge is unknown, start
out with a timer setting of one hour or less.
hold (On timer switch):
This
cancels out Timer function, allowing for
continuous operation. Use for charging
more than 3 hours, such as when the 2
amp charge rate is selected.
Warning!
Monitor charging and stop charge when
battery is fully charged.
Volt/amp selector switch:
Use Volt/
Amp Selector to choose charge rate or
engine start setting (OFF, 6VOLT 40AMP /
100AMP, 12VOLT 2AMP, 12VOLT 10AMP,
12VOLT 40 AMP, or 12VOLT 200AMP).
ammeter:
The ammeter indicates
amount of current measured in amperes
that is drawn from battery. For example,
in 40 amp charge rate a typical discharged
battery will initially draw approximately 40
amps. As battery continues to charge,
current will taper to 15 to 20 amps at full
charge. When cranking an engine, starter
motor draws up to 200 amps. The meter
needle will register to extreme right side
while 2 amp charge rate indicate minimal
activity on Ammeter.
nOte:
The meter
doesn’t have the resolution to display such
low rates.
do not depend
on reading ammeter
to approximate how long charging
will take.
Even at full charge, ammeter
will still provide as much as 50 percent
of charger’s output rating. Sometimes
conditions such as a cold battery, a
sulfated battery, or a deeply discharged
Lead Calcium battery (on many newer
cars) may cause ammeter to read near
a full charge when charging process is
only beginning.
nOte:
Cold batteries (at
or below 32° Fahrenheit) begin charging
at low rate and then increase as battery
warms. When battery charges up, rate will
decrease at a normal rate.
do not charge
a frozen battery.
shOrted Batteries
will read on am-
meter as a high end peg at beginning of
charging process. If after 5-10 minutes,
needle does not move off high end, the
battery probably has a short circuit. Un-
plug charger and discontinue use. Have
battery checked by a qualified technician.
preparing the Battery
If necessary, remove the battery
1.
from the vehicle to charge it. When
removing the battery, disconnect the
grounded battery cable first.
reminder:
Turn off vehicle’s engine
before removing, replacing, or
charging a battery.
