If the battery needs topping up the usual way to do it is with distilled water, which you can buy.
In a battery. Okay, okay... it's probably sold as "sulfuric acid" in auto parts and/or hardware stores.
A small iron electric sheild that supports the acid as well as protect the inside of the battery.
no
Helps the battery to hold charge for a long period of time by charging the cells of the battery. So always check if you need to top off the battery acid fluid in your battery if its not servicable battery then you cant really check it you will need a special tool that you hook up to it that will read for you if battery still has good or bad charge.
A battery acid is a variety of acid used as an electrolyte in a battery - usually sulphuric acid.
Yes. Used in golf carts and other small vehicles. Google "8 volt batteries" and take your pick.
Almost all automotive stores have that Schucks NAPA pepboys ect. cheap like 12$
They are very common for small devices, but every vehicle has a lead-acid battery, and there are millions of those. Still, if you think about it, if every person had a vehicle that would be one lead-acid battery per person, whilst every person probably has several dry batteries.
Yes. Battery acid is sulfuric acid, and its dissociation in water is HIGHLY exothermic. Adding a small quantity of water to the concentrated acid releases so much heat that the water can reach its boiling point. Think frying bacon, except instead of hot grease spattering (which is bad enough) it's hot concentrated acid. Adding the acid to the water means that only a relatively small amount of acid is being added to a large quantity of water; this helps control the heat production (you should still do it carefully and slowly). "Do dilutions like you oughtta; pour the acid in the watta."
Battery acid is a solution of sulfuric acid and water found in lead-acid batteries. Avoid direct exposure to battery acid as it can be corrosive and harmful to skin, eyes, and clothing. If you need to handle battery acid, use proper safety equipment like gloves and goggles, work in a well-ventilated area, and follow safety guidelines for handling hazardous substances.
Battery acid is made of sulfuric acid, a strong acid.
Your best bet (other than a chemical supply house) is probably a hardware store (drain cleaner) or auto supply store (battery acid). It's not cheap; expect to pay around US $100/gallon for reagent grade.
