I have a Sears Die Hard top of the line...less than a $100 with the vent and works perfectly.

I have had an Interstate battery for two years with great luck. Only about $125 online. Given Ohio winters I keep a cigarette lighter battery tender on her when she has to sit for extended periods. Can't see paying extra for the Doktor's logo.

I'm running Wal-Mart batteries in all the cars listed in my signature. I run two of these all winter with no starting issues. About $60 or $70.

Duralast model 48DL here. 700 cold cranking amps, and a vent tube. $94.99 from AutoZone.

(Oh, and thank you for reminding me that I haven't checked the level of distilled water in the battery for almost 2 years! (It was fine, BTW.)

)

Can someone else please answer the OP's question about specific procedures for replacing the battery in his 987? I've always wondered what steps were necessary in order to keep the newer cars happy when the current is completely disconnected...
