• 12 •
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
The 71219 is a battery maintainer that maintains both 6 and 12 volt
batteries, keeping them at full charge. It can charge small batteries
and maintain both small and large batteries. If you are maintaining
a fully charged large battery, you will be properly utilizing the battery
charger. However, if you were to use this battery charger 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
with this unit.
NOTE: The maintain mode technology utilized in DieHard’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.
Desulfation Mode
If the battery is left discharged for an extended period of time, it could
become sulfated and not accept a normal charge. If the charger
detects a sulfated battery, the charger will switch to a special mode of
operation designed for such batteries. If successful, normal charging
will resume after the battery is desulfated. Desulfation could take up
to 8 hours. If desulfation fails, charging will abort and the CHARGING
(yellow) LED will blink.
Aborted Charge
If charging can not be completed normally, charging will abort. When
charging aborts, the charger’s output is shut off and the CHECK
BATTERY (red) LED will blink. To reset after an aborted charge, unplug
the charger from the outlet, wait a few moments and plug it back in.
12. Battery percent and charge times
