No, you should not put salt in a lead-acid battery.
Lead-acid batteries use sulfuric acid (H₂SO₄) as the electrolyte to store and release electrical energy. Adding salt (which contains sodium or other ions) can interfere with the chemical reactions inside the battery. It can cause corrosion, damage the battery's internal components, and significantly reduce its lifespan.
If you want to maintain a lead-acid battery, it’s important to only use the appropriate electrolyte (usually sulfuric acid diluted with water) and follow the manufacturer's guidelines. If you're trying to restore or repair a battery, there are specific methods (such as desulfation) designed for this purpose—adding salt is not one of them!
