Maintenance And Care; Troubleshooting And Error Codes - Schumacher Electric DSR125 Manuel D'utilisation

• The more a battery is discharged, the faster it absorbs a charge from the charger. That means that the
battery % increases faster at the beginning of the charging process than at the end. In other words, it
takes longer for a battery to accept the last few percent of the charge than the first several percent.
• If a battery is not disconnected from the charger, the battery % will be retained through START/STOP
button presses.

15. 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 on the handle, clipped together, on or around
metal, or clipped to the cables.

16. TROUBLESHOOTING AND ERROR CODES

Error Codes
CODE
The battery voltage is still under 10V
(for a 12V battery) or 5V (for a 6V
F0 1
battery) after 2 hours of charging.
The charger cannot desulfate the
F02
battery.
The battery was unable to reach the
F03
"full charge" voltage.
The connections to the battery are
reversed or are made incorrectly.
F04
The charger was unable to keep
the battery fully charged in maintain
F05
mode.
The charger detected that the battery
F06 may be getting too hot (thermal
runaway).
The charger shut off because its
F07 internal temperature exceeds limit.
The battery voltage dropped too low
during the maintain mode.
F08
The Lithium Ion (LiFePO
F09 continues to read 0 V and is unable to
be charged.
The voltage on the Lithium Ion

REASON/SOLUTION
The battery could be bad. Have it checked or replaced.
The battery could not be desulfated; have it checked or
replaced.
Have the battery checked or replaced.
The battery is connected backwards. Or for multiple
batteries being charged, the connections are not proper.
Unplug the charger and reverse or correct the connections
to the battery(s).
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.
Make sure the charger does not have the side ventilation
holes blocked. Move the charger out of the sun and into
the shade.
