lithium battery issues

Agree with Dan.
There are extra loadings on batteries at this time of year with lights, demisters, PCM, aircon, wipers etc. and if you' have only done relatively short journeys over the festive period, the charging system may have been unable to cope.
One word of warning, don't let the battery discharge any further as once the voltage drops, the battery will shut down completely and cannot be charged without "reawakening" it with a boost.
If you are still having problems, it'll be time for a workshop electrical check.

Why will new battery sort the problem?
What is / was causing the drain on the previous batteries?

Latest news, I had the battery replaced by the OPC at great cost. All warnings have stopped. I had kept the battery up to full charge using a lithium trickle charger before taking it to be replaced. Mainly as I did not want a dead car.
Speaking to other Porsche engineers, popular opinion says Porsche has stopped providing their cars with Lithium batteries and gone back to lead acid because of the problems their customers were having with the Lithium batteries. Porsche were making the batteries themselves at the time. That has now stopped. I wonder why?
Hopefully no one else has this expensive experience.
As to what caused the alarm to appear, no information yet, nothing on the car was causing the current drain except perhaps the faulty circuit board that comes with the battery.
