A:
At a
voltage of
more than
8 V, the
battery will
be detect-
ed as a 12 V
battery.
B:
At a volt-
age of be-
tween 8 V
and 10.5V
trickle
charging is
activated
(1 A pulsed
charging
until the
voltage
reaches
10.5V).
C:
If a volt-
age of
10.5 V
is not
achieved
within 30
min, the
battery is
recognised
as defec-
tive.
