In order for the battery to last longer and maintain its maximum capacity, the following conditions must be met.
Keep the battery and its surroundings clean. The surface of the battery must always be dry, otherwise surface leakage currents may occur between the individual banks, due to which the battery will discharge itself.
The electrolyte level must always be at the ring located on the bottom side of the filling chamber. Distilled water should be used for topping up.
In cold weather, do not leave the battery uncharged, otherwise the electrolyte in it will freeze. Weakly charged batteries freeze already at temperatures around -10°C.
