Need car battery for DeepRacer. Where to get replacement parts?

Is there a parts list for the DeepRacer that includes Amazon links to the parts used or where replacements can be obtained? I need a replacement for the car battery and have not been able to find one that will actually attach to the car - the plug types are different. Where can I buy a replacement for either battery? I need the small one, but might as well get spares for everything.
