Are my car batteries dead?

Which every day car puts 18v out of the alternator on start up ?

As for a weak battery messing with the ECU's etc, yes this can happen but it is usually pretty obvious (eta to someone that knows what they are looking at when diagnosing). As I said, if it starts and runs fine then there are no issues to worry about for the moment with slightly low voltages on the OP's batteries.

Thanks. Saved me saying it. I was referring to a transit connect.
