The battery concentration should be around 36-28% sulfuric acid solution. I have decided to go with 37% acid solution. I would like to confirm if the volume of acid to be added is correct. So, using a 98% ACS reagent sulfuric acid the volume of acid to make 100mL solution should be 37.57% right?
When working with the acid, it is important to use a borosilicate glass container, as it is resistant to the acid. Use distilled water, as tap water can contain impurities that can affect the battery’s performance. To make battery acid, you will need to mix distilled water and concentrated sulfuric acid.
As long as you can obtain sulfuric acid, it’s not difficult, but you must be extremely careful handling it. To make acid for a lead-acid battery, dissolve sulfuric acid in water. The acid-to-water ratio is usually between 1:4 and 2:3 (20-40% sulfuric acid), depending on how much gravity you need.
You should never add sulfuric acid into the battery except in rare circumstances. Only add distilled water to the battery. We need to understand the operation of the battery to know why acid should never be added to the battery. The battery electrolyte plays a key role in the ability of the battery to store charge.
Sulfuric acid suitable for battery acid refill can be purchased at many industrial supply stores or online. However, it’s important to handle sulfuric acid with extreme care as it is a highly corrosive substance that can cause serious injury if not handled properly. What is the process for creating lead-acid battery plates?
The correct method to mix sulfuric acid with distilled water for battery use is to add the acid to the water slowly, while stirring constantly. This is important because adding water to acid can cause a dangerous reaction.
