What is electrolyte?
A. Electrolyte is the mixture of sulphuric acid and water in a lead-acid battery. The operation of the battery is affected by the specific gravity, quantity, purity, etc., of the electrlyte within the cell. It is the weight of the acid-water mixture compared to the weight of an equal volume of water. Pure water has a specific gravity of 1.000. Concentrated sulphuric acid has a specific gravity of 1.835. Specific gravity of battery electrolyte in an industrial truck battery is normally from 1.280 – 1.315 when fully charged and 1.110 when fully discharged. • Q. What is a sealed battery? A. Sealed batteries are really Valve Regulated Lead Acid, which mean that after they are manufacture they cant be opened; when the battery charge and discharge it recombine in the gassing process. They are also commonly known as Sealed Maintenance Free because you dont have to water the battery. Other feature is that the electrolyte will not leak out. There are two technologies that make this possible: •
