These Batteries -A- must be replaced.
"Refresh charging" is not permitted for VW vehicles, because voltage surges can damage the on-board electronics.
The Battery -A- must always be disconnected from the vehicle electrical system when using the "Refresh charging" mode.
Always set the mode that corresponds to the Battery -A- during the charging process. Refer to the :VAS5903 Operating Instructions.
"Refresh Charging" is suitable for wet batteries, which must be filled with distilled water.
Do not use "refresh charging" mode on maintenance-free wet batteries.
"Refresh charging (Refr)" mode is only used on Batteries -A- that are possibly defective (sulfation). The Battery -A- is then charged to the maximum specific gravity of the electrolyte and the plates are reactivated (removal of sulfation layer).
The Battery -A- temperature must be at least 10 °C (50 °F).
