Assuming it was a good 12 volt battery, and by wrong, it was the wrong amperage for your car to draw on to start, I'm not sure how it generated all of those engine indicators.

Mayby it was bad, in the sense it had a bad cell, putting out an incorrect voltage, causing a bunch of CEL Codes to set.

(Is it possible that the Tech hooked up the Battery backwards....!!!!!)

It might just be a matter of resetting any codes, and see if they reappear.

Not sure if Autozone or Advanced will reset codes, you might need the Dealer, or find a friend with a Code Reader that can also provide a reset.

I know when I disconnect my Battery to perfom some work, when I reconnect, sometimes I'll get a little arcing at the post, but it never throws any Codes, or Engine lights...
