Charging mode Charging step Battery voltage
12 V / 3.8 A
COLD
Continuous charging At a battery voltage of 14.8 V to 15.5 V,
the charging process continues with
a charging current of 0.8 A.
Changeover to trickle
charging At a battery voltage of ≥ 12.8 V, the
battery is kept at the fully charged
level with a trickle charging current
of 50–150 mA (0.05–0.15 A).
Continuation of the
charging process At a battery voltage of < 12.8 V, the
charging process continues with a
charging current of 0.8 A.
Protection against wrong polarity
The appliance is protected against improper start-up. In case of a faulty connection
or if the battery voltage falls below 7.5 V for 12 V batteries and below 3.7 V for 6 V
batteries, the appliance remains in standby mode.
• In the event that the terminals have the wrong polarity (are connected
incorrectly), 14 is displayed.
• If the terminal clamps are incorrectly connected and the electric circuit is not
closed, the display shows 2 12 .
• If the battery itself is faulty,
13
lights up on the display.
You cannot operate the appliance.
Overheating cut-out
If the appliance temperature exceeds 115 °C, the overheating cut-out is triggered,
and the charging process is interrupted until the appliance has cooled off. The display
continues to show the charge level.
