OEM Gen 4 Battery Specs

[Steve M]

I know it is a bit of a long shot, and probably a dumb request on my part, but I'm trying to track down the specs on the OEM battery that came in the Gen 4 cars. I'm specifically looking for the following info:

Cold Cranking Amps (0°F)
Reserve Capacity (minutes)
Weight (lbs)
Manufacturer (like the actual manufacturer, not just Mopar)

I'm just compiling info...here are the specs for a couple of other batteries I've used in my Gen 4:

DieHard Platinum AGM - Group 34/78 (top + side post)
880 CCA (0°F)
135 RC
Weight: 49.0 lbs
Manufacturer: EnerSys

Duracell Platinum AGM - Group 34 (top post)
775 CCA (0°F)
120 RC
Weight: 43.0 lbs
Manufacturer: East Penn

That DieHard Platinum was a heavy mofo.

I appreciate any help.

Steve, sadly I just got rid of an old one a few months ago.

I did a search and found a stated CCA of 600 amps for 2008.

Good hunting.

I know for sure it was 600 cold cranking amps. I was told ( unproven ) that Interstate made those batteries. Can't help with the rest. I would have to believe someone on here still has an original battery shelved someplace.

By the way, Steve...I am still running of Sears Diehard Platinum batteries in our 03, 08, and 10...so far, so good. Did your Platinum fail quickly??

The first Sears Diehard Platinum in the 03 died after the 2nd year and was replaced. At that point, I purchased the Sears charger with the "Platinum setting" for use if needed. This setting defaults straight to 40 amps for the Platinum battery. Most of the time, they all ride Deltran battery Tender Plus units. The battery in the 03 is now in its 11th year.

Admittedly, I am switching to Interstate AGM's (4 yr. full exchange) for our recreational cars as needed.

I’ve got the OEM IV battery in the garage. Just took it it a few weeks ago because I wanted a top + side so i put in a X2 as it was the only 34/78 AGM i could find in stock locally.

I'm pretty sure Interstate batteries are made by Johnson Controls...I'm not sure anyone outside of some old engineering folks would know for sure, but figured it was worth asking just in case someone was sitting on the info. It's certainly not important, but I'm always curious about that kinda stuff.

Truth be told, Steve, my impatience led me to trading that battery in for my current one for no good reason. See this post here for details: https://driveviper.com/forums/threads/21455-Dash-LEDs-Wiring-Expert-Needed?p=355222&viewfull=1#post355222

Bottom line: I was trying to replace a failed LED in my gauge cluster. The LED I ordered to replace it was causing the car to have all the symptoms of a failing battery, but the voltage was solid at 12.8V. I couldn't for the life of me figure out how a $2 LED could cause that kind of issue, so I went ahead and replaced it. It didn't fix the issue. Once I pulled the replacement LED and put the old one back in, everything was fine, minus the LED of course since it was still bad.

I keep my Viper on a Deltran Battery Tender any time it is in the garage, so that battery had a good life, and I know it still had plenty of life left in it. The only drawback was how heavy the damn thing was.

If you can pull the specs and any info off of it, I would be most appreciative. I'm gonna guess it is around 37 lbs. or so with about 100 minutes of RC.

I ended up going top-post only this time, but I did have to redo the end of the 4-gauge power wire that feeds my amp to make it all work. Fortunately, I acquired a hydraulic crimper a couple years ago, and found a source for cheap crimp-on battery terminals that work really well for that application. Crimped that thing on there, put on some adhesive lined shrink wrap, and called it a day.
