Access To Battery Under Front Seat

Hello Porsche Doc,

Can you recommend any tool sets for removing the
2 internal 12 point bolts that hold the front seat  of
chassis for potential battery change. In the manual,
it states I need to replace these 2 bolts once they
are removed with 2 new ones.
 
In an earlier post, you had mentioned for a oil change
you would need to remove torx style 8mm, 10mm bolts
(head size)

I saw some listed at Sears after a recommendation.
Please help!

Thank you Porsche Doc!

Gosh, I can't remember what size those are off the top of my head.  Craftsman tools will do just fine though, you don't need anything special.  It has been awhile since I have had to replace a battery in a Cayenne.
