Aborted Charge
Models XC6 and XC10: If charging cannot be completed normally, charging will abort.
When charging aborts, the charger’s output is shut off and the CHARGING LED will
ash. In that state, the charger ignores all buttons. To reset after an aborted charge,
unplug the charger from the AC outlet, wait a few moments and plug it back in.
Aborted Charge
Models XC12 and XCS15: If charging cannot be completed normally, charging will
abort. When charging aborts, the charger’s output is shut off and the digital display
will show an error code (see the Troubleshooting section for a description of the error
codes). In that state, the charger ignores all buttons. To reset after an aborted charge,
unplug the charger from the AC outlet, wait a few moments and plug it back in.
Desulfation Mode
Desulfation could take up to 8 hours. If desulfation fails, charging will abort. See Aborted
Charge section.
Completion Of Charge
Charge completion is indicated by the CHARGED LED . When lit, the charger has
stopped charging and switched to the Maintain Mode of operation.
Maintain Mode (Float-Mode Monitoring)
When the CHARGED 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 a level determined by the battery type selected.
NOTE: If the charger has to provide its maximum maintain current for a continuous
12 hour period it will go into Abort Mode (see Aborted Charge section). This is usually
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.
Maintaining a Battery (2A Charge Rate)
The Schumacher XC line are battery chargers with a maintenance setting that maintains
both 6 and 12 volt batteries, keeping them at full charge. On this setting, it can charge
small batteries and maintain both small and large batteries. If you are maintaining a
fully charged large battery, you will properly utilize the maintenance setting. However,
if you use the maintenance setting to charge a large battery, such as a marine deep
cycle battery, that was not fully charged, you may lose some of the battery’s capacity.
This would cause the large battery to be unable to hold a charge and become useless.
Therefore, we do not recommend charging a large battery on the maintenance setting.
NOTE: The maintain mode technology utilized in Schumacher’s chargers allows you
to safely charge and maintain a healthy battery for extended periods of time. However,
problems with the battery, electrical problems in the vehicle, improper connections
or other unanticipated conditions could cause excessive current draws. As such,
occasionally monitoring your battery and the charging process is recommended.
Using the Battery Voltage Tester (Models XC12 and XCS15 only)
With the charger unplugged from the AC outlet, connect the charger to the battery 1.
following the instructions given in sections 6 and 7.
Plug the charger AC power cord into the AC outlet, following the instructions given in 2.
section 8.
If necessary, press the BATTERY TYPE button until the correct type is indicated.3.
Read the voltage on the digital display. Keep in mind that this reading is only a 4.
battery voltage reading; a false surface charge may mislead you. Compare the
reading to the chart below.
