- Keep the battery and surrounding parts clean. The surface of the battery must always be dry, otherwise leakage currents will occur between the individual banks, which will cause the battery to self-discharge.
- The electrolyte level should be at the level of the ring and the bottom of the filler space. To top up, use distilled water.
During the cold season, do not store the battery in a discharged state, as otherwise it will freeze. Weakly charged batteries freeze earlier than charged ones.
