6.6. Regenerate/recharge fully discharged 12 V
batteries (regeneration mode)
 Attach the fully discharged battery into the charger and start the charging pro-
cess.
In this regeneration mode the battery is charged until the charger measures a ter-
minal voltage that is high enough for a regular charging mode. The device then
switches automatically to an appropriate charging mode and continues the charg-
ing.

6.7. Device protection function

The device is protected against improper use. If there is a short circuit between the
terminals with the result that the power circuit is not closed (the terminals are not
fixed correctly) or the battery voltage falls below 7.5 V the device remains in stand-
by mode. You cannot operate the device.
If the terminals have incorrect polarity (are connected incorrectly) the error indica-
tor also lights up
If the battery itself is defective,
6.7.1. Overheating cut-out
If the device overheats during charging the charging current is reduced to a lower
output. This protects the device from damage.
NOTE
A low charging current can significantly extend the charging time.

6.8. Removing the battery

Remove the battery from the charger in the following sequence:
 After charging disconnect the device from the mains power.
 Detach the minus pole terminal (black) from the battery's minus pole.
 Detach the plus pole terminal (red) from the battery's plus pole.
 Reconnect the vehicle's plus pole connection cable to the battery's plus pole.
 Reconnect the vehicle's minus pole connection cable to the battery's minus
pole.
6.9. Switch off
 Switch the charger off by removing the mains plug.
