Regenerate / charge deeply discharged 12 V batteries
(regeneration mode)
− Connect the deeply discharged (completely fl at) battery to the charger and start
a charging process.
In this regeneration mode, the battery is charged until the charger measures a
terminal voltage that is high enough for a regular charging process. The device then
switches automatically to a suitable charging mode and continues charging normally.
Description of the charging cycle
Charging mode
Charging stage
Battery voltage
6 V / 0.8 A
Completely charged
At a battery voltage of 3.7 to
7.6 V, charging takes place at a
charging current of 0.8 A.
Switch to trickle charging
At a battery voltage ≥ 6.4 V,
the battery is maintained in a
completely charged state with
a trickle charging current of
50–150 mA (0.05–0.15 A).
Continuation of charging
process
At a battery voltage of < 6.4 V,
charging is continued with a
charging current of 0.8 A.
12 V / 0.8 A
Completely charged
At a battery voltage of 7.5 to
14.8 V, charging takes place with
a charging current of 0.8 A.
Switch to trickle charging
At a battery voltage ≥ 12.8 V,
the battery is maintained in a
completely charged state with
a trickle charging current of
50–150 mA (0.05–0.15 A).
Continuation of charging
process
At a battery voltage of < 12.8 V,
charging is continued with a
charging current of 0.8 A.
12 V / 3.8 A
Pulse charging
(reactivation of the
battery)
At a battery voltage of 7.5 V to
10.5 V, charging takes place with
a pulse charging current of 0.8 A.
Continuous charging
At a battery voltage of 10.5 V to
14.1 V, charging is continued with
a charging current of 3.8 A.
