Maintenance And Care; Troubleshooting - Motorola MT146 Owner's Manual

COMPLETION OF CHARGE
Charge completion is indicated by the
Charged/Maintaining (green) LED.
When solid, the charger has switched to
maintain mode.
MAINTAIN MODE
(FLOAT MODE MONITORING)
When the Charged/Maintaining
(green) LED is solid, the charger has
started maintain mode. In this mode,
the charger keeps the battery fully
charged by delivering a small current
when necessary. 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

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.

replaced.
MAINTAINING A BATTERY
This unit maintains 12 volt batteries,
keeping them at full charge. It can
charge and maintain both small and large
batteries.
NOTE: The maintain mode technology
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.
• 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.
Check for open fuse or circuit
breaker supplying AC outlet.
Check power cord and
extension cord for a loose
fitting plug.
No problem; this is normal.
Press the START/STOP
button to start charging.
