Any pedal car enthusiasts out there?

While in Illinois I bought a child's car at an antique store.

It is not a pedal car but takes some sort of battery. It is a Keeblers Indy car. I cannot find any names on it but it has a small electric motor with a reduction gear attached to the right rear wheel. there is two small foot operated switches and a two prong plug which apparently goes to the battery. There is a small bracket for a battery under the tail of it. The size of the battery is about 2.5" tall and 5.5 x 9" length and width.

I would like a battery to fit the bracket that can be charged over and over and will not have any ability to spill acid.

Any ideas?
