Explanation
In batteries that need maintenance, you must check the electrolyte level (a mixture of water and sulphuric acid). It must cover the plates inside the battery; if not, add only distilled water. In maintenance-free batteries, you need to check that the terminals are clean, tight and coated with grease.
