REACTIVATION (ONLY FOR OPEN 12V ACID BATTERIES)
Caution: This function may only be used with 12V lead-acid batteries disconnected from the vehicle, as the high charging
voltage of up to 15.6 V poses a risk to the 12V on-board electronics in vehicle systems, car paintwork could be damaged by
battery gassing and the service life of light bulbs is reduced.
After selecting reactivation, the display shows the warning message
Closed lead-GEL and AGM as well as lithium iron phosphate (LFP / LiFe-
PO4) batteries must not be reactivated!
This function is intended to reactivate deeply discharged lead-acid batteries.
However, defective lead-acid batteries (cell short circuit) cannot be reactivated
with this function and must be disposed of properly.
Reactivation is started by connecting the battery and pressing the "Start" key. The display shows "REACTIVATION ACTIVE".
If an error message "No battery connected" appears instead, no battery, a deeply
discharged battery (battery voltage less than 3 V) or the battery cables have been
connected incorrectly (reverse polarity). Reactivation starts automatically as
soon as a functional battery is connected.
After completion of the reactivation charge (4h), the device automatically swit-
ches to trickle charge. This is shown in the display.
Reactivation can be interrupted at any time by pressing the "STOP" key, and the
display jumps to the basic menu. The charger is switched off by pulling the mains plug out of the socket.
With a reduced charging current over a limited period of time, the charging voltage is increased to such an extent that the
battery begins to produce gases. This results in an acid rearrangement in the battery and a partial degradation of the sulfate
layers, which has a positive effect on the performance and service life of the battery. Please note that the battery develops
explosive oxyhydrogen gas during this phase. After reactivation has been completed, it is essential to check the battery's
acid level and, if necessary, top it up with distilled water, as reactivation usually leads to a loss of liquid in the battery.
ATTENTION
In the "Reactivation" mode, the charger does not automatically switch to error after removing the battery clamps from the
battery to be charged.
The charging voltage is still present at the charging clamps.
When reconnecting the charging clamps to a battery, an accidental reversal of the battery polarity can therefore not be
detected!
