In a lead acid battery, the electrolyte is a mixture of water and sulfuric acid. This mixture allows for a chemical reaction to take place between the lead in the electrodes and the sulfuric acid, which creates an electric current. The electrolyte also helps to keep the lead electrodes from corroding.
In order to increase the electrolytes in a battery, you need to add more of the ions that make up the electrolyte solution. This can be done by adding more of the salt that is used to create the solution, or by adding other acids or bases to the solution.
