I replaced the battery in my 2000 996 in December 2012 with this from Walmart - just under $99.87 + $9 core.

At least an H7 used the center mounting hole on my '03.

Counts describe captured discussions, not unique people or a diagnosis. Author identities are not reliably stored. Exact duplicate evidence is counted once across matching discussions; one discussion counts at most once per action/state. Multiple repairs reported together remain a combination. Suggestions and failed attempts do not establish a fix. Matches cover whole discussions and can include related faults, model variants and incomplete threads.

I put in a Bosch Group 48 battery from Pep Boys two weeks ago. Perfect fit for the terminals, mounting clamp, and even the drain hose. Price was $108, but there was a 20% coupon that I printed from their website, which brought the price to under $100
Best battery, or best for $50?

I prefer AGM (Absorbed Glass Mat) Gel type batteries
I replaced an Interstate MTP-H7 With a Braille 7548 AGM battery - direct replacement.

Battery sizes that fit 996 (group 49 will probably need a nut under the last, unthreaded, hole in the tray)

Krazy
I like AGM batteries not for weight. Like sizes weigh pretty much the same as standard flooded lead acid batteries.
I buy for performance. (Why buy expensive Joe Gibbs oil when Shoprite reclaimed oil will work or a $100k Porsche when a $15k Nissan Versa will get you to your destination for less $$?)
I have AGM batteries in the 1972 911 that are 12 years old and going strong.
I just replaced the 11 year old AGM battery in my BMW motorcycle this spring. Prior flooded lead acid lasted 4 years. It was still working but 11 years on a bike battery was long enough for me.
I also like that the AGM doesn't need a vent and can't spill. They can be used laying on their side if that floats your boat.
These are the same enthusiast that quibble over oil, thermostat, suspension, tires, aero kits, brakes, etc...
Everyone wants their car to be a race car, what are you smoking?
Frank, I know the AGM's as well but just didnt need it for my 996. Some of our AGM's at work have not lasted like yours. Maybe the high amp loads hurt them. My response wasnt directed at you, just OP. I posted before I saw yours. Sorry if it sounded bad.
I ended up buying a
Group 49 Bosch at pep
dudes
The unthreaded hole was a easy fix
I removed the battery tray
Installed a 2 inch 14/20 SS
Held in place with lock nut
and JB Weld
Now I just use same battery
bracket with ring nut
This is the largest battery
And best deal
Now I'll start another debate by asking
Everybody's opinion on a battery maintainer
Thanks All
That looks like a nice alternative to $$Braille$$
H7 is between 48 and 49. At least an H7 used the center mounting hole on my '03. The 49 would use the last, unthreaded hole.
