Charging batteries
Before you start Before you start to charge batteries read the “Important Safety
Instructions” on page ix and take all safety precautions when working
with batteries.
To charge your batteries:
1. If possible, disconnect all loads from the battery, by removing battery
cables, by opening a disconnect switch, or by switching loads off.
The charger detects a battery is fully charged when its charging
current drops below a preset limit. The presence of electrical loads on
the battery may interfere with this detection method. A timer-based
charge termination feature acts as a backup, but the charging current-
based method is preferable.

Charging Current indicator
lights
These lights indicate the charging current.
At transition points when the current is
changing, two indicator lights may flash
alternately, then settle into the new charging
current reading. This happens because the
current is between the two values indicated
by the two indicator lights.
Note that the indicator light values are
minimums. For example, the 10 amp
indicator light indicates current in excess of
10 amps.
