As temperatures rise so does evaporation. So do car batteries need water? The simple answer is yes they do.
The lead-acid batteries that power most cars have six cells that use a lead oxide paste and lead sulfate in a sulfuric acid solution. During the chemical reactions that provide power to your engine water is lost from the battery cells.
Most batteries have some means of indicating when they need water. Check your battery frequently especially if you live in a hot climate to make sure the cells are topped off.
If a cell is allowed to go dry the lead oxide paste will form lead sulfate. When this happens the battery won’t be able to hold a charge and will need to be replaced.
If you do need to add water use only distilled water. Do not use tap water which can contain minerals that will damage the battery cells.
To prevent your battery from drying out have it serviced regularly. A good battery maintenance program will include frequent testing and adding water when needed. It’s also a good idea to keep your battery clean to prevent corrosion.
