Look into the Deka brand of batteries. Very happy with their AGM #9A 78DT AGM with a great warranty. Just replaced my present one after 5 years with a new one---AND---- THEY ARE MADE IN AMERICA!!!!!!!!

When the sears near me closed up I got the DH AGM and its been in the car for a while now - on battery tender most of the time - no issues with it.

Braille. Have one in a Mini Cooper. Original lead acid weighed just shy of 50 pounds, Braille weighed 11! Deka is similar and probably cheaper.

Edit: I wrote Deka was similar originally but its actually an Odyssey my buddy uses that is similar to Braille.

I don't expect a car battery to last more than 5-6 years. My 2001 C-5 has had Optima "red tops" in it since 2002, when the first round of "leakage scares" occurred, with the OE Delco batteries. Every 5-6 years, I buy a new red top and either put the old one in my "winter beater", or give it to a friend. But FWIW, I've never had an issue with any of the Optimas........

You don't need to depend on them to cite an application. If it fits in the hole and the terminals are of the correct type and on the correct sides, you can use it.

As I noted in a similar thread a few months ago, I have been very happy with my Autocraft (Johnson Controls) group 78 AGM battery 740 CCA 115 min 60 Ahr, that I bought at Advance Auto.

Some may insist on a 120 min rated AGM battery, so those would include;

Rural King (Exide) #RK-AGM78 group 78 AMG battery 770 CCA 120 min 60 Ahr
Deka/East Penn 9A78 Intimidator group 78 AGM battery 775 CCA 120 min 55 Ahr

You could add to the list - Interstate MTZ-78 AGM CCA 800 CA 1000 RC 125

...with a 62 Ahr rating as well. That is very nice battery, but somewhat expensive too.

Not sure of the year that the OP has, but a 1997-03 can use a group 78 side post AGM battery.

1997-00 came from the factory with Group 78 wet cell battery (can be upgraded to Group 78 AGM)
2001-03 came from the factory with Group 75 AGM battery (can be upgraded to Group 78 AGM)

2004 came with a top post Group 86 AGM battery (same size as Group 75) (can be upgraded to a Group 34 AGM)

Group 78 battery is 10-1/4" L x 7-1/16" W x 7-5/16" H
Group 75/86 battery is 9-1/16" L x 7-1/16" W x 7-5/16" H

Group 34 battery is 10-1/4" L x 6-13/16" W x 7-7/8" H
