How much liquid is in a 12 volt battery?

A typical 12-volt lead-acid battery contains around 1 to 1.5 liters of electrolyte solution, which is a mixture of sulfuric acid and water. The exact amount can vary depending on the battery's design and capacity. However, in maintenance-free batteries, the electrolyte is often absorbed in a sponge-like material, making it less accessible. Always refer to the manufacturer's specifications for precise information.
