The amount of battery acid you should add to distilled water depends on the size of your battery. Typically, you should add enough acid to bring the specific gravity of the battery to the correct level. This is usually between 1.215 and 1.260 for most lead-acid batteries. Can you use distilled water instead of battery acid in a lead-acid battery?
