higher than the battery's resting voltage.

12. USING THE VOLTMETER TO TEST BATTERY STATE OF CHARGE

OVERVIEW
The charger has a built in voltmeter 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 eventually
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 by turning
on the lights or other accessories.
The battery tester is only designed to test
6V and 12V batteries. Testing a device
with a rapidly changing voltage could yield
unexpected or inaccurate results.
TESTING SEQUENCE
There are three basic steps required to
test the battery state of charge:
1. Connect the battery charger's clips
to the battery. Be sure to follow all of
the precautions listed under sections
6 and 7.

13. BATTERY PERCENT AND CHARGE TIME

This charger adjusts the charging time in
order to charge the battery completely,
efficiently and safely.
The duration of the charging process
depends on three factors:
Battery State
If a battery has only been slightly
discharged, it can be charged in less than
a few hours. The same battery could take
up to 10 hours if very weak. The battery
Battery Type button),
POWER CONTROL
To keep the unit from exceeding its input
current level specification of 15 A, all
charging stations are connected by an I
(pronounced "i squared c") communication
bus, and power data is accumulated by
one station communicating with all other
stations. If the power is greater than 850 W
(this corresponds to an input AC current of
about 15 A), the max current of all stations is
reduced from 12 A to 7 A. After 2 minutes, if
the total power is still above the 850 W, the
max current of all stations is reduced to 4 A.
Then, after two more minutes, if the power
persists above 850 W, all stations are turned
off. After any of these power reductions,
excluding shut down, if the total power drops
below 600 W for 1 hour, the max current in
all stations is then increased back to 12 A.
2. Connect the charger's power cord
to a 120 VAC outlet. Again, be sure
to follow all of the precautions listed
under sections 6 and 7.
3. Read the voltage on the digital meter
or press the
to set the tester to % (Battery %) and
read the battery percentage.
TESTER AND CHARGER
When first turned on, the charger operates
only as a tester, not as a charger. To
continue to use it as only a tester, avoid
pressing the START/STOP button. The
charger is always in tester mode until the
START/STOP button is pressed. Pressing
the START/STOP button activates the
charger and deactivates the tester.
TESTING AFTER CHARGING
After the unit has been changed from
tester to charger (by pressing the START/
STOP button), it remains a charger as
long as it's connected to a battery. Press
the START/STOP button again to change
back to tester mode.
state can be estimated by using the built-in
tester. The lower the reading, the longer
charging will take.
Battery Rating
A higher rated battery will take longer to
charge than a lower rated battery under
the same conditions. A battery is rated in
Ampere-Hours (AH), Reserve Capacity (RC)
and Cold Cranking Amps (CCA). The lower
the rating, the faster the battery will charge.
