Electrolyte level too high
Note:
If the electrolyte level is too high, escaping electrolyte (mixture of sulphuric acid and water) will cause damage
outside the battery, e.g. on components in the engine compartment.
- -> If electrolyte level is too high (overfilled), i.e. if level is above inner electrolyte mark (plastic web) or above
outer max. mark, excess electrolyte must always be drawn off using a commercially available hydrometer.
- Use hydrometer to draw off sulphuric acid until electrolyte level reaches plastic web/max. mark.
