WARNING
Risk of injuries! Pay attention to the warning notes and security norms
Chapter
.
Caution
The
“servicing charging”
procedure must not be executed when the
Battery
A
is installed in the vehicle, because the current peaks can damage the on-board electronic system.
If, despite everything, the
“servicing charging”
operation is carried out with the battery still in the vehicle, the
Battery
A
should be disconnected from the on-board system.
Caution
During charging, always set the type of operation corresponding to the
Battery
A
Instruction manual of the
Battery charger
VAS 5900
!
The
“servicing charge”
operation is only permitted for:
Standard batteries that have been topped up with distilled water.
Gel/AGM batteries.
Do no use the
“servicing charge”
operation in maintenance-free standard batteries
Chapter
.
The
“servicing charge (SERV)”
operation is only used when damage to a
Battery
A
is suspected (for example, leakage). In this case the
Battery
A
is charged to the maximum density of the electrolyte and the plates are reactivated (elimination of the sulphate layer).
Special tools and workshop equipment required

Note
The
Battery
A
should always be at a minimum temperature of 10 °C.

meaning
“normal charging of standard batteries”
or symbol
2
meaning
“normal charging of Gel/AGM batteries”
will appear.
Set the battery capacity (Ah) with the
“Up”
↑
or
“Down”
↓
adjustment buttons.
Connect the red charging terminal
“+”
of the charger to the positive pole of the
Battery
A
.
Connect the black charging terminal
“-”
of the charger to the negative pole of the
Battery
A
.
The charger recognizes the nominal voltage of the
Battery
A
connected (6 V, 12 V or 24 V) and starts charging automatically.
Once charged to about 80 - 85%, the charger begins
“final charging”
. A fourth bar appears on the display
1
. The
Battery
A
is ready for use.
When 100% charged, all the bars will appear on the display
1
.
Note
The success of the
“servicing charge”
depends of the level of sulphate in the
Battery
A
.
Troubleshooting:
The
Battery
A
voltage indicated does not correspond to the nominal voltage:
Keep pressing the
“Up”
↑
or
“Down”
↓
button until charging begins.
The
Battery
A
voltage indicated does not correspond to the nominal voltage - charging has already begun:
Press the
START/STOP
button twice.
Keep pressing the
“Up”
↑
or
“Down”
↓
button until a new charging begins.
The charger does not recognize any
Battery
A
if the voltage is lower than 2 V:
The information on the display remains unaltered:
The type of
Battery
A
and the amperes/hour (Ah) set are displayed.
Finalizing
Battery
A
charging:
Press the
START/STOP
button.
Disconnect the black charging terminal
“-”
from the charger of the negative pole of the
Battery
A
.
Disconnect the red charging terminal
“+”
from the charger of the positive pole of the
Battery
A
.
Disconnect the charger from its power source.
