Solar Battery Maintainer -VAS6102A- Device Description

Solar Battery Maintainer -VAS6102A-

The Solar Battery Maintainer -VAS6102A- supports the vehicle electrical system and prevents the Battery -A- from self-discharging.

The Solar Battery Maintainer -VAS6102A- reaches a maximum voltage of 14.3 V and a maximum charge current of 255 mA.

All chargeable lead- and lead gel batteries can be charged with the Solar Battery Maintainer -VAS6102A-.

The Solar Battery Maintainer -VAS6102A- is connected to the diagnostic connection in the vehicle.

The Solar Battery Maintainer -VAS6102A- has a green LED integrated inside the frame which displays the function being performed. The brighter the LED, the higher the charging current.

It is not possible to overcharge the Battery -A- due to the integrated electronics.

Severely Discharged Batteries

  WARNING

Risk of injury. Follow all warning messages and safety precautions. Refer to → Chapter "Warnings and Safety Precautions".

A Battery -A- is designated as "severely discharged" if the resting voltage is less than 11.6 V.

  WARNING

Do not check or charge a Battery -A- when the visual indicator has "no color or is bright yellow". Jump starting must not be used!

There is a risk of explosion during testing, charging or jump starting.

These Batteries -A- must be replaced.

  Caution

  • Severely discharged Batteries -A- freeze earlier.
  • Batteries -A- that have frozen must no longer be used.

  Note

  • Batteries -A- that have not been used for a long time will discharge by themselves.
  • In severely discharged Batteries -A-, the electrolyte consists almost completely of water, because the acid portion has been greatly reduced.
  • Severely discharged Batteries -A- become sulfated, meaning all of the plate surfaces of the Batteries -A- harden.
  • The sulfation process may be reversed if a severely discharged Battery -A- is recharged immediately.
  • If the Battery -A- is not recharged, the plates will continue to harden, and the ability to accept a charge will decrease. This results in reduction of battery performance.
  • Severely discharged Batteries -A- in vehicles must be replaced prior to delivery. Pre-existing damage cannot be ruled out.

Procedure

- Check the Battery -A- resting voltage. Refer to → Chapter "Battery, Charging".

- Charge the Battery -A-:

  • Battery Charger -VAS5095A-. Refer to → Chapter "Severely Discharged Battery, Charging with Battery Charger -VAS5095A-".
  • Battery Charger -VAS5900-. Refer to → Chapter "Severely Discharged Battery, Charging with Battery Charger -VAS5900-".
  • Battery Charger -VAS5903-. Refer to → Chapter "Severely Discharged Battery, Charging with Battery Charger -VAS5903-".
  • Battery Charger -VAS5906-. Refer to → Chapter "Battery, Charging with Battery Charger -VAS5906-".
