Flat Battery

[spid]

Hi All
Moved across from TVR ownership 2 months ago, needed a more reliable car,so brought a 996 and its broken down. Started at home fine, drove 5 miles into town stopped at the cash point got back in turn the key Click Click and the alarm goes off volt meter shows flat battery. Charged battery over night and drove to garage and they can't find a problem. Any ideas? Luckily still have the TVR to get around in

I know EXACTLY what the problem is. You've got a Porsche mate.

Buy a battery charger. Mysteriously you'll see lots of adverts at the back of Porsche magazines.

No Porsche day out is complete without a flat battery to kick it off. Mine was on Sunday when I was ready to set off for Brands

Mrs K can't believe how fast I can now get it jumped from one of the other cars!

Many porsche are not used frequently and hence batteries don't last too long. Generally should be replaced every 3 years or so.

My battery decided to give up the ghost while sitting in the 993 register display at Brands Hatch on Sunday afternoon. Very embarrassing.

I bought a new battery from Porsche Tonbridge today - the service manager pointed out that the flat battery (which I'd taken in for advice) was dated 2001 and said that, in all probability, it had simply 'worn out'. Certainly, in cars I've had previously, four years was a good age for a battery - it was often less. Given the amount of drain that a good modern alarm system takes out of a battery, it's perhaps hardly surprising that they're often in need of a top up charge.

Garage said battery tested fine and car is charging

Strange, i can leave my car for up to 4-5 weeks at a time and the car will start straight away. Battery is abot 18 months old.

Get car tested at specialist for earth leakage.

It's also worth cleaning up all the earth straps on the vehicle and ensuring good contact.

Some alarm systems seem to drain Porsche batteries.

Has alternator checked out OK?
