D
esulfation Mode
If the battery is left discharged for an extended period of time, it could become sulfated and not accept normal charge. If you select
, the charger will switch to a special mode of operation designed for sulfated batteries. For the best performance, AUTOMATIC
CHARGE Mode is recommended for Desulfation Mode. If successful, the charger will fully desulfate and charge the battery, and then
the green LED will light. Desulfation could take up to 10 hours in AUTOMATIC CHARGE mode. If desulfation fails, charging will abort
and the charger will go into Abort Mode. If MANUAL CHARGE mode is selected and the timer is set to between 10-120 minutes,
desulfation will stop at the specified time. If the timer is set to HOLD, the maximum time for desulfation will be 10 hours.
C
ompletion of Charge
Charge completion is indicated by the CHARGED (green) LED. When lit, the charger has stopped charging and switched to the
Maintain Mode of operation. If you are charging a deep cycle battery, the CHARGED LED comes on when the battery is charged
enough for normal use.
M
aintain Mode
When the CHARGED (green) LED is lit, the charger has started Maintain Mode. In this mode, the charger keeps the battery fully
charged by delivering a small current when necessary. The voltage is maintained at 13.2V.
100A Flash Reprogramming
NOTE:
DO NOT
attempt to Flash Reprogram a vehicle that has a discharged or defective battery. Make sure that the vehicle battery
is in good condition and fully charged before proceeding. In Flash Reprogramming Mode, the charger is able to deliver 70A charging
current continuously, and to deliver up to 100A for three minutes.
1.
Set MODE to FLASH REPROGRAM. (The VOLTS LED will start blinking.)
2. Use
▲
and
▼
to adjust voltage to the voltage needed for the vehicle being programmed (refer to OEM specifications). Voltage selected
is shown on the digital display. The unit has a voltage range of 13 to 14.8, with a default of 14.2.
NOTE:
When the VOLTS LED stops blinking, the display shows the selected voltage.
3.
Press to turn on the output.
4.
When finished with Flash Reprogramming, press t
o exit this mode.
U
sing the Battery Voltage Tester
Overview
This battery charger has a built-in voltmeter to measure your battery’s voltage. 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 for a couple of minutes before you read the display.
Read it a couple of minutes after you have turned the headlights off.
Testing Sequence
: There are seven basic steps required to test the battery state of charge:
NOTE:
You cannot test the battery voltage while charging.
1.
With the charger unplugged from the AC outlet, connect the charger to the battery following the instructions given in Sections 6 and 7.
2.
Plug the charger AC power cord into the AC outlet.
3.
The CONNECTED (yellow) LED will light if a properly connected battery is detected.
4.
Confirm the CHARGING (yellow) LED is off.
5.
Set the DISPLAY to VOLTS.
6.
If the output is on, press
●
. If the output is already off, do not press .
7.
Read the voltage on the digital display.
G
eneral Charging Notes
Fans:
The charger is designed to control its cooling fans for efficient operation. Consequentially, it is normal for the fans to start and
stop when maintaining a fully charged battery. Keep the area near the charger clear of obstructions to allow the fans to operate
efficiently.
NOTE:
The charger has thermal protection, and it will shut down if it gets too hot.
Voltage:
The voltage displayed during charging is the charging voltage and is usually higher than the battery’s resting voltage.
11. CALCULATING CHARGE TIME
11.1.
U
se the following table to more accurately determine the time it will take to bring a battery to full charge. First, identify where your
battery fits into the chart.
11.2.
NR means that the charger setting is NOT RECOMMENDED.
11.3.
F
ind 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 percent charge prior to recharging. Add more time for severely discharged batteries.
