Battery Replacement

Looks like time for a new battery for my gen 2 997 Turbo S. I am trickle charging it so it is OK for now, but think I will need a replacement (trying to avoid the humiliation of a jump start at the local supermarket). Is this something I can get myself or would you recommend taking it to my OPC? I have heard things about not losing memory during the battery swap.

If this is a DIY job, any battery recommendations? I only do about 7k miles per year, which might be part of the problem.

Also, and sorry for the stupid questions....can I safely use the trickle charger (Porsche Charge O Mat) with a car cover on? I heard it needs ventilation but assume this means directly around the battery.

Many thanks in advance!

James, a question to ask is about the extended warranty? If you have it then you need to replace it with a Porsche battery. If you are not in extended warranty then Bosch make a possibly better replacement. When changing the battery- leave the key in position 1 and make sure you leave everything open (for obvious reasons of not wanting to get locked out.) From there it is a simple swap out, sometimes an error may show but they normally clear with usage. Ventilation would be a small confined space with no air flow- so not the usual garage conditions...[:)]
 
Very good article on this subject here https://www.porscheclubgb.com/forum/tm.asp?m=802733 ...and I've changed the OP status to member so you can view the above link...[:)]
 
Mine sits on its Ctek charger routed out from under the bonnet with its indoor Porsche oem cover on quite happily.The only heat generated is from the charger unit itself which is on the wall outside the car. Dave...
 
It´s out of Extended Warranty so I am looking at Bosch options so thanks very much for the advice. Not that I value the Extended warranty that much...last time I tried to claim I think the only possible claim scenario involved leap years and Paraguayan flamingos.[:D]

Over the last couple of years warranty work on my car has been around double the premium. The HP fuel pump alone was two years premium! Still, like any insurance it's only worth paying for it if you need it... Good luck with the battery. Why do you think it needs changing, BTW? They have very good testers these days to check battery health.

Yes, insurance sometimes pays out. I´m just a victim of Sod´s Law ;-) I think I need a new battery for the following reasons, but I am far from an expert: The battery is 4.5 years old. I don´t get to drive the car every week as I travel a fair bit. Despite driving the car 3 days in a row without problems, the battery was stone dead on Monday. It recovered with the trickle charger on overnight. Sounds sluggish on start up now. From a bit of research, sounds like one of the cells may have gone and many suggest replacing battery every 3-4 years. But I may get it tested....what do you think? Many many thanks again!
 
Mine is 5 years old and still, apparently, in good health (kiss of death). It does sit on a conditioner at all times when not in use. I think if a cell has gone on yours it wouldn't charge up or start the car at all. I still it it's worth getting it tested before shelling out on a new one.
 
Some chargers have a recondition function and this works really well- just don't use it too frequently though, say once a year. I know the ctek ones have this feature and has saved a battery or two.
 
in the last 3 weeks watched 3, 997 s on lowish mileage , all about 2 years old ,die from dead cells ............2 GTS s and 1 speedster ..........Porsche main agent tells me this is quite usual .................not on my '72 s batteries approaching 10 years or '86 turbo se only 5 years old and the list goes on .................sorry find 2 years unacceptable !

Porsche batteries can fail in less than 5 years. However your battery could be just run down from lack of use. If a modern car sits alarms etc continue to drain the battery. If your battery recovered enough to start the car after one nights trickle charge it could be okay as the maintenance device will have done little charging in such a short time. Try a proper charger or borrow a ctek with a boost function and leave the car until the charger shows it as fully charged. If it fails after this then you will know remedial action is necessary.
 
Hi Buy yourself an Optimate 6, this is a fantastic piece of kit. It will recover, desulphate and check your battery. I also have a ctek and it is good as a trickle charger. I have four cars in storage and swap the chargers around every couple of weeks and also leave the batteries with no chargers hooked up for about 3 weeks. this cycle has worked well as i have not replaced a battery in ten years or so. Consider the Optimate 6 a long term investment. Regards Hugh
