Battery keeps on going flat, and it used everyday! Only replaced battery in december, went to start yesterday after not driving it for a day and completely flat!

Lights/nothing was left on. Anything I can check??
 
Do you have anything after market such as Alarm stereo etc or is just standard Porsche Equipment ?
It looks like you have a leak or a short somewhere... Is everything working as expected ???
One other thing to check is the alternator as it might be faulty and not charging the battery properly

Bad luck, I had battery problems in January, but a change to Halfords' finest resolved the problem.

There's a comprehensive topic on Battery problems on the 996 FAQ... worth a look:

OTOH if it's a battery capacity problem, I'd recommend an Optimate charger to keep you topped up.

OK. The only thing that can be considered non factory standard is the VTS but I would start from the alternator. Have it checked in case it does not charged the battery properly

You should also probably have someone do a discharge test on the battery... it's the only proper check and it will eliminate that as a possible cause. :bye:
