Dead Battery

i did ask on the forum about best practise when leaving car standing and nobody said disconnect battery.. in fact people said it would be fine and that they had left theres for longer. i would expect a modern car to be able to cope with this as well...so that is what is making me think that it was a duff battery caused by non working alternator.
i cant do anything about it now anyway .. will wait till i get back,solve the problem in a nice civil way... if i have to spend my time off with no car and ford garage p i ssing me about then im gonna be mad .
anyway thanks for all your replies.

Got to say you've been given bad advice there i'm afraid

It's expecting too much of even a modern battery to maintain it's charge even when stood for 3 months.

For various systems in the car to keep working there is a very small current drain even when the ignition is turned off - the alarm and keyfob receivers for example. Over 3 months of standing still this will drain the battery even if there was no deterioration from non-use.

Not sure of the ST's battery spec but if you take it at being 70Ah then being stood for 3 months (2160 hours) you've got roughly 32mA maximum that the battery can be supplying continually over that time without any deterioration in the battery charge over that time. If you were to factor in the hefty amount of current drawn to operate the starter motor after being stood for that time you're lowering that 32mA even further.

If you saw the waranty bill we have for replacing batteries at pdi because the battery care process hasn't been followed during storage you'd soon get the gist that it's not a battery or alternator issue. And that'll be for cars which have intelligent modules which are put into transport mode to limit functionality while the vehicle is in transit with the very purpose of limiting battery drain.

ok then.im gonna say that i will be happier if it is down to the fact that the battery has been drained.means £70 and a hard learnt lesson. but no worrys about having no transport whilst im home.thanks for your time.im really looking forward to the exhaust note and full boost..also will like seeing my son as well happy motoring and thanks again ... ste

Sorry you've found this out the hard way mate.

Hope it's not long before you're rolling again and having that feeling
