TESTING AFTER CHARGING
After the unit has been changed from
tester to charger (by selecting a desired
rate), it remains a charger. To change the
battery charger back to a tester, press the
RATE SELECTION button until all 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.

DESCRIPTION
battery, following the instructions given
in previous sections.
2. Plug the charger AC power cord into
the AC outlet.
3. Start the vehicle, rev the engine at 2000
rpm for 30 seconds and turn on the
vehicle's headlights or other accessories.
4. Read the voltage on the digital display.
If you get a reading between 13.4 volts
and 14.6 volts, the alternator is working
properly. If the reading is less than
13.4 volts or more than 14.6 volts, refer
to your vehicle's manual or have the
charging system checked by a qualified
technician.
• 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, on or
around metal, or clipped to the cables.
REASON/SOLUTION
The battery could be bad. Have it checked or
replaced.
The battery could not be desulfated; have it
checked or replaced.
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.
The battery is connected backwards. Unplug the
charger and reverse the connections to the battery.
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.
The charger automatically shuts the current off
if it detects the battery may be getting too hot.
Have the battery checked or replaced.
