so my factory warranty is going to expire on friday. i had a PPI-like inspection done and one of the things the tech found was a bad battery. their tester showed very high impedance and he told me even though my battery holds the charge and car starts fine, it is bad.

when i took my car in for service/repairs (getting a new steering rack), i mentioned it to the service adviser. however, the dealer said that their battery tester showed the battery to be fine "as far as the warranty is concerned"

so my question is multi-part: since i dont know much about how battery works, what is high impedance? is it something i should escalate to Porsche Customer Service and get them to replace? or should i just pay $100-$200 and get a new battery and forget about this whole thing? or should i just keep on driving until existing battery dies?

thanks....

Replace the battery.

the battery isn't covered under warranty so you don't have much to say to PCNA

High impedance effects a car battery the same way restricted arteries and blood vessels effect impotence. Your battery MAY want to crank hard and long, but can't get enough flow to make it happen.

so where do i get a new battery from?
