In the very late 1800s they were used in electric cars.
Absolutely. Used hybrid cars are just as useful as used gasoline cars. There are fears that the batteries are "used up" in used hybrid cars, but the lifetime of the batteries is very long and this should not be a problem.
A 7.2 volt battery is used in most remote control cars. They are also called RC cars and some places sell RC batteries for these specific cars. There are most likely other batteries that can also be used.
Cars and bicycles.
Nickel Metal Hydride or Lithium Ion batteries are the most widely used.

I don't think there is such a thing as a "diesel battery". Perhaps you mean the batteries used in diesel cars; the batteries usually used in cars are lead-acid batteries, the acid being sulphuric acid.
No, the batteries in an electric car are much different. Normal automotive batteries are lead acid batteries. Most electric cars use Lithium-Ion batteries.
By using solar energy to charge the batteries
How do the cars solar collectors work together with the batteries?
Fuel. But for new cars like some Toyota can run on batteries.
sulfuric acid is clear and is used in lead acid batteries for cars.
They don't. They use wet cell batteries.
