Explicit resolution reports before identified causes, performed actions and suggestions. Within each level, matching component labels precede direct query mentions and inherited thread context; successful versus unsuccessful discussion counts, owner confirmations and independent discussion support determine order. This is not a probability of success.

It was running at around 13-14V when it ran last week, but I have just tried to start it now as the car has been standing for a week while I was on holiday and it won't start now at all, so I need to take it to the PC next week as the battery is still under warranty with them.

Coverage and how to read this overview

Counts describe captured discussions, not unique people or a diagnosis. Author identities are not reliably stored. Exact duplicate evidence is counted once across matching discussions; one discussion counts at most once per action/state. Multiple repairs reported together remain a combination. Suggestions and failed attempts do not establish a fix. Matches cover whole discussions and can include related faults, model variants and incomplete threads.

POST 1 / ORIGINAL POSTEROriginal post

I recently had a new Moll battery fitted by my OPC 6 months ago and over the last month or so the car has been slow to turn over again. I take the car out a couple times a week for various driving routes as normal still. Does this sound like the alternator failing? Also, does anyone routinely use a battery charger / conditioner like the CTEK ones advertised in the owners magazine or are these just if you store your car over the winter months etc?

POST 2Original post

If you are taking it for a run twice a week, you definitely shouldn't need a battery conditioner. What is the voltmeter reading when the engine is running? If it is c.14-15 Volts, then the alternator is probably charging OK. That being the case, I would first get the battery load tested, and if that checks out OK then it sounds like a parasitic drain somewhere. The drain could be the alternator regulator pack, which is quite common, but if it is charging OK, then it would be best to get the battery itself checked. The Porsche/Moll ones aren't the best quality. Probably the accountant's choice of battery.....

POST 3Original post

Have used the CTEK battery conditioner since 2008. Always connected when the car is garaged for the night. Recommended.

POST 4Original post

If your car is not under a Porsche warranty, do yourself a favour and buy a Bosch S5 silver battery and never worry about batteries again...

POST 5 / ORIGINAL POSTEROriginal post

It was running at around 13-14V when it ran last week, but I have just tried to start it now as the car has been standing for a week while I was on holiday and it won't start now at all, so I need to take it to the PC next week as the battery is still under warranty with them. I thought the Moll would be the best being original Porsche fitment, but it appears Bosch are superior then, I will know for next time!
