USING THE BATTERY VOLTAGE TESTER
1. With the charger unplugged from the AC outlet, connect the charger to the battery, following the instructions given in previous sections.
2. Plug the charger AC power cord into the AC outlet.
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. Compare the reading to
the following chart.
6V Battery Voltage Reading 12V Battery Voltage Reading
Battery Condition
6.4 or more
12.8 or more
Charged
6.1 to 6.3
12.2 to 12.7
Needs charging
Less than 6.1
Less than 12.2
Discharged
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 the Charge/Maintain rate and GEL 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 Rate Selection
button until all charge rate LEDs are off.
NOTE: The battery tester is only designed to test batteries. Testing a device with a rapidly changing voltage could yield unexpected or inaccurate results.
12. MAINTENANCE AND CARE
A minimal amount of care can keep your battery charger working properly for years.
• Clean the clamps each time you are finished charging. Wipe off any battery fluid that may have come in contact with the clamps to prevent corrosion.
• Occasionally cleaning the case of the charger with a soft cloth will keep the finish shiny and help prevent corrosion.
• Coil the input and output cords neatly when storing the charger. This will help prevent accidental damage to the cords and charger.
• Store the charger unplugged from the AC power outlet in an upright position.
• Store inside, in a cool, dry place. Do not store the clamps clipped together, clipped to the handle, on or around metal, or clipped to the cables.

Error Codes
CODE
DESCRIPTION
REASON/SOLUTION
bAd
bAT
F01
The battery voltage is still under 10V (for a 12V battery) or 5V (for
a 6V battery) after 2 hours of charging.
The battery could be bad. Have it checked or replaced.
bAd
bAT
F02
The charger cannot desulfate the battery.
The battery could not be desulfated; have it checked or replaced.
bAd
bAT
F03
The battery was unable to reach the “full charge” voltage.
May be caused by trying to charge a large battery or bank of batteries on too low
of a current setting. Try again with a higher current setting or have the battery
checked or replaced.
F04
The connections to the battery are reversed.
The battery is connected backwards. Unplug the charger and reverse the
connections to the battery.
bAd
bAT
F05
The charger was unable to keep the battery fully charged in
maintain mode.
The battery won’t hold a charge. May be caused by a drain on the battery or the
battery could be bad. Make sure there are no loads on the battery. If there are,
remove them. If there are none, have the battery checked or replaced.
bAd
bAT
F06
The charger detected that the battery may be getting too hot
(thermal runaway).
The charger automatically shuts the current off if it detects the battery may be
getting too hot. Have the battery checked or replaced.
If you get an error code, check the connections and settings and/or replace the battery.
Troubleshooting
PROBLEM
POSSIBLE CAUSE
SOLUTION
Battery clamps do not spark when touched
together.
The charger is equipped with an auto-start feature. It will
not supply current to the battery clamps until a battery is
properly connected. The clamps will not spark if touched
together.
No problem; this is a normal condition.
Three LEDs come on for 2 seconds, then
turn off.
The charger is plugged into an AC outlet.
No problem; this is normal.
