2) For regeneration mode, make sure to disconnect all connections between the battery
and the vehicle electrical system.
3) On certain vehicles it is essential not to disconnect the vehicle electronics from the
power supply on battery replacement. In such cases, the power supply mode can be
used to power the vehicle electronics whilst changing the battery. If load voltage is
below 7.5 V, the charger will change to standby mode. There is no reverse polarity
protection in this mode.

4.1 Pulse charging
This is an automatic charger function which cannot be selected manually.
If the 12 V battery voltage in mode 1, 2 & 4 is between 7.5 V (± 0.5 V) and 10.5 V
(± 0.5 V) at the start of charging, the charger switches automatically to pulse.
If the 6 V battery voltage in mode 6 is between 3.75 V (± 0.5 V) and 5.25 V (± 0.5 V)
at the start of charging, the charger switches automatically to pulse
4.2 Trickle loading phase
The charger has an automatic trickle charging phase with max. 1.2 A when fully
charged.
4.3 Maintenance phase
When the battery is fully charged, 100% icon will light up, the charger enters
maintenance phase to keep the battery capacity in full condition.
4.4 Memory function
If the charger is disconnected from the mains during charging, the unit stores the mode
implemented. On re-connection to the mains and if the battery is of the same type (6 V
or 12 V), the unit starts up automatically in the last mode. In the case of a different
type of battery (6 V and 12 V), it switches to standby.
Caution: If the type of battery connected is different from the last memory (for example,
the last time was cold/AGM mode, and you need to connect a normal WET battery this
time), please manually reselect the mode to avoid overcharge and damage.
There are no memory function for mode 4 (Quick Mode), mode 5 (Regeneration
mode), mode 7 (Power Supply mode) and mode 8, 9 (Push mode).

alternatively, the charger is trying to judge battery voltage. After 1-3 minutes, the
charger will judge whether the battery is a 6 V or 12 V battery and it will enter
corresponding 6 V mode or 12 V car mode.
4.6 Override Mode
If the charger detects that the connected battery is a 6 V battery and enters 6 V mode,
but the user is very sure that it is a 12 V battery, the user can press and hold the mode
button for 5 seconds to switch the charger to any 12 V charging mode.
ICAUTION
Please only use this override mode if you are sure that the battery to be charged is a
12 V battery. The 12 V mode can charge the battery already from 3.75 V low voltage.
Therefore, a 6 V battery could be overcharged and further dangers (increased gas

4.7 Device protection function
In the event of a short circuit at the charging cable, the fuse (5b) on charging cable
prevents damage to the device and the electrical system.
5 Maintenance and care
Always unplug the mains connector before cleaning the charger. The device is
maintenance-free.
1. Turn off the device.
2. Use a dry cloth to clean the plastic surfaces of the device.
