That is a 730CCA. It doesn't say if it has a vent, if it is right or left hand positive and there is no picture available. Also compare the dimensions to your current one.
When I swapped mine, I needed a longer cable. Just went to an Autozone and bought a generic one with the old one in hand so I knew the length, what the ends looked like and "wire thickness".
Get anti-corrosion "rings" (to go over the posts before the cable clamps get secured) while you are there.
Get a vent adapter tube in case the vent tube is in a different location from the standard Moll.

blog on batteries says:
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.
