996tt battery keeps going flat???

Hi all..... i dont really use my 996tt much, but should the battery go flat after say 5 days? its had a new battery last Aug 09, i double lock lock the car so it shuts down, but i cant understand why the battery goes flat so quick?? surelly it should last longer than this? I rang OPA Leeds, who fitted the battery, as it has a 2 year warranty, yet they said this normal??? and will charge to check if the battery has a drain?? thought this was a bit unreasonable... Any ideas?? although will buying a ctek trickle charger next

flat battery I have a 2003 targa with a new battery in 2009 and im lucky to start it after only 2 days.It really puts the damper on owning such a great car.Bought the car at xmas and it has a 3 month warranty so will hopefully be sorted.I even leave the fuse box cover off permanently so I can jump it easily.I only need to drive it about 6 or 7 miles and it will start first time every time for about 24 hours,so it is obviously charging ok but draining when parked up.

It seems to be a Porsche thing, although 5 and as said 2 days is unreasonable and would point to a drain somehwere. The thing I and many others do if your car is not a daily runner is to hook it up to a trickle charger when not in use. (Continuous full drain of a battery will ruin it very quickly.) They are a godsend and keep the battery charged up by allowing a small amount of charge to top it up. Once full it goes between a charge and discharge to ensure the battery is not damaged and therefore can be left on for weeks or months at a time. The C-tec charger seems to be the make most use. I dont but mine does the same thing. Its the only way :thumb:

Do you mean the battery is actually going flat (so you can't crank the car) or do you mean that the remote stops working after 5 days? This is normal, as the alarm system goes into energy-saving mode after 5-days, disabling the remote function. BTW, double-locking only disables the interior monitoring sensor - nothing else.

Thanks for the replies... The car battery actually goes flat, if i try and start the car after say 5 days, it sets the alarm then and then the start motor just makes a ticking noise.... It is such a pain, when my BMW if even left for a week and half will start with ease... its weird...

I think your battery is faulty as mine was like that until it was replaced. Now lasts 3 weeks ish which still isn't brilliant but... Cheers

Battery hi Guys have a 2003 cab and the car started ofter three weeks no problem if your battery is only lasting 2 to 5 days then there is a serious drain or the battery is no good make sure you have a good charge when running about 14v is normal also if you have it checked make sure they keep the tester on for more than a few seconds regards steve :thumbs:

I have also a 996 tt and there is no problem with mine - it starts easily and without any problem after 3 weeks of non use.

over the last few months, have done a couple of nearly 6 weeks inbetween drives and started both times,mind only just but it started :thumb:

There does seem to be a common problem of current drain when the car is parked up, and this may be your issue too. AA or similar can do a test to measure it to confirm that is the problem. Diagnosis is then more tricky, I know that tracker units can draw current if their internal battery fails, if that happens they will change the unit without too much fuss. Also remember a post on here about current draining back through the alternator when parked due to a failed diode (electrical equivalent of a one-way valve as I understand it). Good luck with it. Fix the cause then change the battery and life improves no end! And lots of folk reckon the Halfords 4 year guarantee is good insurance - two batteries for the price of one!!
