Me and my brother bought a battery from Ford spare parts and couldn't wait half a day for them to install it, so we did it ourselves.

Long story short, after replacing the battery, the car threw out a transmission error so we had to bring the car back to the dealer.

Talked to the service guys and they said the car needs to be notified when a new battery is installed to reset that special charging thing Ford has going on otherwise the car will throw errors.

I changed my own battery, no error codes thrown. door unlocked (left open) key in ignition, positive terminal off first and on last.

Re: fuel consumption, (predominantly a function of throttle position) Sure, save yourself 1/3rd of a horsepower in parasitic drag by complementing the charging system with a Ag Ca battery.

My foot moves more then that potential saving- headwinds, gradients, overtaking.

But to spend big dollars over cheaper alternatives, one must convince oneself that the extra money is well worth it. This I understand.
