    My 2009 with ~157k is still on the original battery. Don't know how long it will last. Last voltage check with Autel scanner shows almost all have voltages close to each other. Forgot the exact number. Cleaned the battery fan few months back . Car is driven daily for roughly 35+ miles.

    Just want to find out who have the most mileage and oldest battery. Curious to know.
