How does a battery work?
Your battery works by having two metals, a cathode and anode, react to each other to create chemical energy that we harness as electrical energy. With wet cell lead-acid batteries, these metals are kept in a liquid electrolyte, a liquid solution comprised of pure water and hydrosulphuric acid mixed to a set specific gravity. Other types of batteries typically use a gel, mat, or solid electrolyte to perform the same function. For the purpose of this topic however, the only battery we’ll be discussing is the traditional lead-acid battery, as this is the only type of battery for which you will have to worry about electrolyte levels.
