The AGM is low internal resistance by design, so it will deliver whatever demand (starter) at a higher amperage, than even a larger battery of flooded cell type.

I happen to have an Odyssey battery in everything I own (11 batteries currently), startups are much quicker. Battery longevity of 8-10 years, with more reliable performance throughout.

Since I do not know how old the battery is in my Z and the prior owners did not maintain the car to my standards I went ahead and purchased the PC 925L Odyssey battery.

It is smaller, weighted about 6 lbs less than the ac Delco 75A 630CCA battery, and easily outperforms it.

I got the stinger battery post adapters from eBay.

Installation was a little tricky with the positive terminal on the left but I got it in with no problems.

I used the factory battery bolt and rubber mount to help secure the battery along with drilling a couple of small holes in the battery tray and some tie downs to secure the battery down.

So far so good! The car started quicker than normal and runs with no issues. Maybe the old battery was dying, who knows.
