what a load of rubbish if the battery is bad enough to need that you need to turn everything off then it needs changing simple as that.

You might want to waste money buying a new battery, but as I said I squeeze all the life out of mine. That's my preference.

Still never come across a car that the manual states "allow dash lights to go out." Only old diesels with heaters.

A worn battery will be playing silly !!!!!!s with the alternator, which will be using more fuel to charge

In other words you have come across them. And others as I said have peculiarities on start up proceedure. And others I just allow the ECU to boot up anyway, which I consider good practice.

Alternator current is only increased at low revs which is partly why the manuals say to drive off as soon as you are started, and only significantly increased (at this point) if the battery charge is very low, and if it were very low it would be unlikely to start the car. At higher revs the alternator is in a sustained mode despite the battery condition. Besides which I check my battery charge and charging system regularly.

Have to agree with Benham on this one, trying to squeeze the last penny out of an old battery is false economy, sooner or latter it will catch you out. OK the AA and RAC drains will accept this but not me.

The modern ecu takes alot out of the hands of the driver, including this issue.
