Overview
Connect the battery following the precautions listed in Sections 6 and 7. 1.
Select the appropriate settings for your battery. 2.
Connect the AC power following the precautions listed in Section 8. 3.
Automatic Charging
If the charger has an Automatic Charge Mode, it can perform an automatic
charge. When an Automatic Charge is performed, the charger switches to the
Maintain Mode (see below) automatically after the battery is charged. For a
battery with a starting voltage under 1 volt, use the Manual Mode first to pre-
charge the battery for five minutes to get additional voltage into the battery for
the charger to analyze.
Manual Charging
If the charger does not have an Automatic Charge Mode, you will be charging
in Manual Mode. A manual charger will continue to charge and will not shut off.
You must keep a visual check on the ammeter to determine when the battery is
charged. Be sure to monitor the charging process and stop it when the battery
is charged. Not doing so may cause damage to your battery or result in other
property damage or personal injury.
Completion of Charge (Automatic Chargers Only)
When the FULL CHARGE (green) LED is lit, the charger has stopped charging
and switched to the Maintain Mode of operation. If the 12V DEEP CYCLE
battery type was selected, the CHARGED (green) LED comes on when the
battery is charged enough for normal use.
