Size 47 battery in the 996

[LVDell]

So with all the talk recently of what size non-porsche battery goes in the 996 and answer was 48, but 47 and 49 will will just fine as well, I decided to post my experience with this.

My battery decided to die last week so I went out to get a replacement. Not as easy as it looks. Nobody carries the 48 in stock in town at any of the discount part places. So I found a great deal on a 47 at Costco for $47.99 and installed it yesterday.

I have attached a picture of it in the car installed so you can see the difference in size. For those of you that track you car, this sucker weighs much less as well.

As you can tell I only had to move the bracket over one place holder to secure it.

Oh yeah, almost forgot. This battery has the optional red cap mod that gives you an extra 10hp! :jump:

Hi Dell...

Glad you mentioned the red cap mod. It is perhaps the least expensive way to increase horsepower that not many people know about.

Thx...

Speaking with the folks over at my local Porsche dealership service department they advised that if I changed the oil filter cap from the standard stock yellow cap to the new black 996-107-035-51 my gas mileage would improve. So I did. After three tanks full of Shell V-power, I can honestly say my gas mileage is up by almost 20%.

I gotta get that mod! Heading down to the dealer right now. :)

That round purple sticker is a date code. The battery was made in July 2004. Batteries do not like to sit around. When I get a battery I sort through them to get the newest.

$48 sure beats $150 from a dealer.

[LVDell]

Darn, I wish I new that. There were a few different stickers. How do you read the sticker? I am guessing that 7-4 is July of 2004 but G-4?

[Tool Pants]

7 is for July and G is also for July since it is the 7th month. The 4 is for 2004. Sometimes Consumers reports is good for something.

[LVDell]

Thanks Jeff. There were some others in the queue that had orange stickers but I don't remember what the date stamps were. Next time in costco I will check em out and if there is a deifference of 6+months newer then I will swap out the one I bought. Costco has a very liberal return policy.

I am still waiting for some fanatic to tell you that now you have disturbed the weight balance of the car since the battery is no longer centered.

[LVDell]

No doubt! I am sure it is coming sooner or later. Some people get a bit up tight don't they? My answer will be so I have more weight on the left side of my car for the high speed oval track event! Totally kidding of course, but it sounds great.

[Tool Pants]

You need the weight on the drivers side to balance the passenger weight.

Here is my Costco group size 25 battery I bought for my old Toyota truck in January 2005. Battery was made in January after I sorted to find the newest on the rack. Not all battery companies use date stickers, some brand the date in the plastic. Strange looks when you take batteries off the shelf and take pictures at Costco, Sears, and Auto Zone.

And some people make fun of Consumer Reports.

[LVDell]

That's too funnny. THanks for the pic! I am off to Costco to makes sure there wasn't a battery significantly newer than mine.
