Battery Specs
 

My battery is 9 years old and needs replacing. I can't find cranking amp or other specs for replacing it. What is the best battery to get for our 986? I don't need any special low weight or other custom, just a factory replacement is fine.

Thoughts?

Everything you ever wanted to know about 986 batteries:

My last two have been Interstate ones from Costco, lasted 4 and 7 years.

Very helpful!

There are three threaded holes for the battery hold down.

You can fit
H6
H7
H8

H8 is a battery for diesels and I wouldn't advise it.

If you have a battery that lasted 9 years then perhaps we should be asking you for details.........

i bought the Porche from my brother in law 2 years ago. I've kept it in low tender charge during the past 2 winters. It is a Duralast battery and it happened to click and reset the clock recently when I went to start it; so I checked the date 12/09. I assume it is 9 years old this December. That's all the details

The 986 (Model years 1997-2004) takes a BCI Group 48 (12.1X 6.9 X 7.6"), the 987 (2005-) takes a BCI Group 94R ( 12.4 X 6.9 X 7.5 "); both right hand positive terminal. The 94R is also slightly lower in CCA.

The 986 Tiptronic battery is bigger than the manual transmission version. They are listed this way in the general section of the official repair manuals:
Ah/A 60/280 Manual
Ah/A 70/320 Tiptronic
So buy a bigger CCA battery if you live in colder climes, drive a TIP Boxster, or have a bigger amp in the car.
