Part of the sulphuric acid used to form the plates is retained by the battery and has a specific gravity between 1.25 and 1.35, the amount of the retained acid being insufficient to electrically connect the plates during storage. In addition means is provided to seal the battery against ingress of air but allow gases generated in the battery to escape.
