Arguing got it down to $7.5k and beyond that I needed a lawyer. I paid it, and kinda regret it, because not only is it a refurbished battery, it's basically useless on a trip/supercharger now as they cap the speed to absurdly low levels. Like 10%/h. Car only had 70k miles on it, too.

I appreciate that you didn't call me a liar, which has been my past experience anytime I mention something negative about that company
