Ensuring the optimum electrolyte level
Topping up cells with water
A vented battery contains demineralized water in each cell. Together with sulphuric acid, this water ensures that the chemical process functions perfectly. Each cell must be supplied with sufficient water. If the lead plates in the cell are "dry", there is a risk of damage and capacity reduction. It is therefore important to maintain the water level. However, the water evaporates during charging and discharging.
To ensure optimum battery performance, it is therefore necessary to check the water level and refill it regularly. This maintains the electrolyte level that connects the positive and negative plates in the battery. It is important that the battery is not overfilled. If the battery is overfilled, it will leak through the fuel filler caps during use and charging.
