For 24V chargers: multiply all voltage values by 2.
NORMAL (14,4V): recommended for flooded flat plate lead
antimony batteries (starter batteries), flat plate gel and AGM
batteries.
HIGH (14,7V): recommended for flooded lead calcium batteries,
Optima spiral cell batteries and Odyssey batteries.
Eight step charge sequence for lead-acid batteries:
1. CHARGE/TEST
Tests if the battery can accept charge, even if the battery is
fully discharged (zero or nearly zero Volt across the
terminals).
All charge status LEDs will flash in case of reverse polarity
connection, short-circuit or if a 12V charger is connected to
a 24V battery.
The TEST LED will flash as long as a charge pulse does
not increase battery voltage to more than 12,5V resp. 25V.
If the flashing persists during several minutes the battery is
probably damaged (internal short-circuit): disconnect the
charger.
A false rejection may occur if a load is simultaneously
draining a very weak or fully discharged battery during the
test phase: disconnect the load and repeat the test.
