Which 12V Battery Do You Have Installed?

[Karl]

Is that a 330cca battery in your car?

I have a battery relocation kit (not installed yet) and really do not need the side mount battery which seems to cost more.

Cold Cranking 330
Pulse Hot Cranking 900 (5 seconds)

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.

ODYSSEY batteries are made by Enersys...not Johnson Controls. The Odyssey brand was formerly HAWKER a military spec.

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.

I have been running the Odyssey 75-PC1230 exact fit for a few years now and very pleased.

760 CCA, 815 MCA, 1050 HCA
1230 Cranking Amps for 5 Seconds
110 Minute Reserve Capacity
Cycle life @ 77° F 400 at 100% DOD
-40° F to 140° F Temperature Range

I also put Odyssey batteries in the Mercedes and Audi daily drivers, and will change out the Harley original battery with an Odyssey next year. I’m sold on Odyssey!!

Unless that Delco is an AGM battery it is inferior in many ways.

I just took an ac Delco unit out.

i use Delco Battery

It is a great battery if you are not keeping your ZR-1 stock.

The one I use is the PC925L and it is smaller and weights 26lbs. Car fires right up!
