- Acid-resistant grease, such as BOSCH pole grease.
- Steel wire brush (brush for cleaning poles and terminals).
- Densimeter.
Necessary consumables: Distilled water.
Cleaning the battery terminals
When servicing your vehicle, you should also clean the battery terminals and poles and lightly lubricate them with acid-resistant grease.
Checking the electrolyte level
In serially installed car batteries, a single filling with electrolyte is usually sufficient for their entire service life. However, the electrolyte level should be checked regularly.
Warning: Do not expose the battery to open flame. Explosive hazard!
Unscrew the battery plugs with a large screwdriver or coin and check the electrolyte level.
The electrolyte level in each individual element should be approximately 10 mm above the lead plates. If the level is too low, top up the electrolyte to the prescribed value.
Caution: Use only distilled water to refill the level.
Screw in the battery caps and tighten them securely.
