Best Answer

Automotive batteries generally have a liquid electrolyte in them. The electrolyte is usually a solution of sulfuric acid and water. Occasionally, under adverse conditions some of the water will evaporate. Some auto batteries have caps, plugs, or covers on the top of the battery allowing you to add water if the liquid level drops. However some [if not most today] auto batteries [sometimes called "Maintence Free"] do not have any way to access the cells to add water. There is also a new "dry cell" type of battery that does not have liquid in it.

Where do car batteries go when dead?

The common, Lead-Acid car battery contains a lot of lead that can (and MUST) be recycled. Most of the Lead used for fabricating new car batteries comes from recycling. Car battery recycling is quite efficient and therefore, the poisonous lead is mostly kept from polluting the Earth, but some people ignore this and let used batteries go to landfills, which is a no-no!
