Caution: Do not expose the battery to naked flame. Risk of explosion.
The electrolyte level should be between the min and max marks -arrow-.
If the electrolyte level position is not visible from the outside, unscrew the cap of one of the cans. The liquid level should be 6 mm above the plates, including the separator. If there are level marks, you should follow them.
The density of the electrolyte together with the voltage measurement allows us to draw a conclusion about the battery charge level. A hydrometer is used for checking. The higher the density of the electrolyte, the higher the float rises. The scale can be read in units of density (g/ml) or degrees Baume (+ Be). The following values should be achieved:
Cleaning the battery terminals
During regular vehicle inspections, the battery terminals and connection terminals should be cleaned and coated with antioxidant grease.
Battery conservation
An unused battery will discharge over time. If the vehicle is not used for a long time, the following measures should be taken.
Check the battery charge level and charge it if necessary.
Disconnect the battery ground cable to prevent it from being discharged by constant consumers, such as watches.
Recharge the battery every three months.
Caution: Check the battery charge level at shorter intervals depending on its age. Do not leave the battery in a discharged state, otherwise the plates will become sulfated.
