With either, gel cel batteries are a favorite, but a simple inexpensive 6 volt can be had from a tractor supply store

Thank you. I read to was suppose to avoid modern oil, so thats why i asked. Any recommendations?

Also, the car has already been converted to 12v prior to me, but idk what size fits in the tray.
