At a battery voltage of < 12.8 V,
charging is continued with a
charging current of 0.8 A.
Reverse polarity protection
The device is protected against being set up incorrectly. If it is connected incorrectly or
the battery voltage falls below 7.5 V for 12 V batteries and below 3.7 V for 6 V batteries,
the device remains in standby mode.
• If the clamps are connected with the poles reversed (connected incorrectly),

You cannot operate the device.
Overheating protection
If the device temperature reaches more than 115°C, the overheating protection is
triggered and charging is paused until the device has cooled down. The display will
continue to show the battery level.
Disconnecting the battery
WARNING!
Explosion hazard!
Improper handling of the charger can lead to sparking and can
trigger an explosion.
Gaseous hydrogen can escape from the battery during the
charging and discharging process. Contact with open fl ame will
cause a highly explosive oxyhydrogen reaction.
− Disconnect the device from mains power before you disconnect
the connection clamps from the battery.
