What causes a battery to reverse polarity?
So I bought a 12v 5 Ah SLA battery on Amazon so I have a portable power source for testing electrical parts in junkyards and such. However, when I tried to charge it, I got a reverse polarity error on my charger. I verified with a voltmeter, this battery does indeed have reverse polarity. So my question is what would cause this? Was it likely mislabeled, or is it possible that it was charged backwards at the factory? Sorry for the dumb question, I'm just extremely curious what would cause this.

If you think a good mechanic is expensive, try hiring a bad one
Re: What causes a battery to reverse polarity?
Also, wouldn't a positive ground car still use a normal battery?

Check that one before install.
FWIW a lead acid battery can be charged up backwards. I've witnessed it.

So the chassis is the ground and the positive terminal connects to it?

Sorry was just trying to make sure I was on the same page as sdaidoji. Lack of caffeine on my end.

at 4,000prm with your explosive refrigerant the AC is probably amazing
realistically, i have a friend that had a cavalier with only first and second gear. the only real problem with driving it like that is 50mph at 4000+ rpm is it is very loud and very embarrassing. he used to get up to speed and put it in neutral. i'm pretty sure the embarrassing car cost him his girlfriend
