Servicing charge with the Battery charger -VAS 5900-
  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 chargerVAS 5900!
The „servicing charge“ operation is only permitted for:
t  Standard batteries that have been topped up with distilled water.
t  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 boards are reactivated (elimination of the sulfate layer).
Special tools and workshop equipment required
   
t  Battery charger -VAS 5900-
  Note
t  The Battery -A- should always be at a minimum temperature of 10 °C.
t  Do not open the caps of batteries with removable caps during charging.
–  Turn off the ignition and all electrical equipment, and remove the key from ignition.
–  Disconnect the Battery -A-.
–  Connect the charger to a power source. The last mode of operation selected will appear on the display → Fig.-1-.
  W00-10182
–  Set the type of operation corresponding to the Battery -A-with the INFObutton.
On the display symbol -1- 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.
  N27-10179
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.
  N27-10170
When 100% charged, all the bars will appear on the display -1-.
  Note
The success of the „servicing charge“ depends of the level of sulfate in the Battery -A-.
Troubleshooting:
1 - The Battery -A- voltage indicated does not correspond to the nominal voltage:
–  Keep pressing the „Up“↑ or „Down“↓ button until charging begins.
2 - 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.
3 - 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.
