Report Abuse. The most common battery acid is sulphuric acid. This substance is extremely dangerous. It is highly corrosive, and it can cause burns if it is in contact with the skin, and inhaling its fumes can severely damage the lungs and other membranes, and the eyes.E: Just how dangerous is battery acid? Ok, first off, I&#39;m referring to the &quot;battery acid&quot; found within a typical alkaline AA battery. Second off, I have an extreme phobia of battery acid so I don&#39;t feel comfortable touching batteries.
Over time the liquid in the battery evaporates, and to keep the battery working it needs to be refilled. Of course, sulfuric acid isnt readily available, so water is used instead. If you just add a little bit of water a couple of times it wont affect the battery too much. Maybe the ratio of water to acid will be 30/70, which wont make much difference at all. If you do this too many times, however, the battery wont charge, and you'll need to replace it. fvazquez468 Â· 9 years ago.
