In a pinch, you can use tap water in a lead-acid battery. Since the minerals dissolved in the water will eventually poison the battery it isn't advisable to make a habit of it. If your reverse osmosis device removes most of the minerals you can probably substitute it for distilled water but you should confirm the quality of the water it produces before making a habit of it. A quick method to check the quality would be to check the water's conductivity. Using an Ohm meter, compare its conductivity to that of distilled water at the same temperature. If the measurements are close then have at it.
Water is required in a lead acid battery.
the more the battery is charged, the less water. dead battery is close to 100% water. charged battery is close to 90 - 100% sufuric acid
The acid in automotive batteries is a sulfuric acid/water solution known commercially as "battery acid". There is about 29 t0 32% sulfuric acid in the solution, the rest is water. The purpose of the water is to allow the solution to conduct electricity by chemical conversion in the cell. As the battery is used the water can evaporate or escape raising the concentration o acid. When this happens the efficiency of the battery is reduced. More water must be added to bring the solution back to the proper ratio of acid and water.
Battery acid has the higher pH.
I assume we're talking about the typical wet-cell battery. Usually it is filled with a mixture of acid and water. If the water is gone the battery is damaged and cannot be fixed by refilling it with acid and water.
30-50% sulfuric acid (H2SO4) in water
