Battery replacement for 02 996 Carrera 4S Help please!!!

I'm looking for a replacement battery for 2002 996 Carrera 4S.  My car has been in the garage all winter and the battery will not hold a charge.  Any recomendations? 
 
 

I just replace mine with an Odyssey

I prefer the Porsche Part myself just to be on the safe side. But that is a personal view and I'm sure there are plenty of good alternative suppliers in the US. So Hot911TTs tip is probable a good choice.

Thanks for the tip.  What made you go with the odyssey battery?  I called a porsche dealership and they would install it for $350.  Is the odyssey a better battery then the factory part?

I put an Odyssey in my car last year when I first bought it. It was recommended by my dealer and supposedly is better than the original part. Since I've only had it for a year, its hard to say.

Everyone told me the Odyssey was the way to go, including my dealer as well.

Hot911TT--did you order one on line or buy through a dealer?

The Porsche battery is junk, so stay away from those.  If you simply want a replacement battery, you can pick up any group 48 battery and it will fit.  It will be a little shorter than the long original battery, but there is another tie down point for that size in the tray.  We usually use interstate group 48 batterys for about $100.  They  seem to last the longest. 

With that being said, you can not leave any battery in a car for months at a time without starting the car and getting the battery charged up.  The battery will drain flat over time, and once it is flat, if it stays there too long, the battery will be shot.  Install a trickle charger and plug that in if you plan on leaving the car sit for more than a week or two. 

I now agree with the Doc. Regards Big Bob

When you refer to interstate group 48 battery, do you mean the MTP-93, MTP-91, and the MT-49?  These batteries were recommended on the interstate web site when plugging in my car.
 
As far as a trickle charger has anyone used a ctek 3300?  A friend of mine highly recommended this one.

Most trickle chargers will work

When you installed the odyssey in your car did you need any mounts or did it come with mounts?

I had mine installed and my independent Porsche dealer said it fit like the original battery. They charge me $350 for the battery and installation.

I am going to go with your recomendation and get an interstate battery.  When you install these batteries, do you need mounts or does it fit in the factory mount?
