I have a 1955 Packard 400 and I need to get a new battery for it. Can I buy a regular battery and then do i hook it up backwards? I read the battery forum and that's what I gathered from the posts but I'm not sure. Lydia

yes. The battery doesn't care.

Metropolitans are manufactured positive ground. Most of us switch them to negative ground so we can use electronic devices.

Yes, they use an ordinary battery. You just connect it "backwards" - positive to ground, negative to power.
