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 Schumacher
maintainers 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.
