OEM Battery

[Tulecreeper]

Messing around the other day, checking the difference in resting vs idling voltages between my wife's Jeep battery and mine (hers may be dying). I've only been under my hood a couple times since I got the truck in March. While looking at the top of my battery, I see:

CCA: 730
RC: 140
Ah: 80
EN: 630

I have never seen mention of RC (Reserve Capacity) or Ah (Amp hours) on any cranking battery, only on the deep cycle or dual-purpose batteries for my boat or RV. Just the mention of RC tells me it is a dual-purpose battery, which is an almost-but-not-quite deep cycle. Why is there a wanna-be deep cycle battery in my truck? Usually, in a boat or RV, deep cycle batteries are used so they can be fairly deeply discharged then recharged again hundreds of times without damage. What possible need would there be for that in a truck?

Also, what does the "EN" mean? Never seen that before. And 140 RC equals about 60 Ah, not even close to 80.

It looks the same as what's in my truck.



The EN rating is just another crazy load test spec.

Yep, same one. I found the "EN" thing is some European designation.

Have you seen any indication of a warranty on your battery? Like 3 or 5 years, or whatever?

IIRC, I was informed that the battery was covered by the 3-year, 60,000 KM warranty.

I'm not very concerned about the warranty because I'm convinced the Mopar battery in my truck is a POS. From day 1 in January of 2022, I was never impressed with cold starts.

I plan to replace it at my own expense the moment it begins to struggle and before accepting a free warranty replacement. LOL

Having just typed that, maybe... I'll take a free warranty replacement and then buy an oversized AGM battery.

I've always made certain that my truck batteries are oversized and very reliable because cold winters suck but a dead battery in the winter sucks that much more.

Since I've only had this truck since March, I don't know yet how trustworthy the battery is. I will agree to the rest of your statement, though. I know this sounds devious, but if your battery is giving you trouble in reality if it is covered under warranty what if it just "unexpectedly died" one day, leaving you stranded and having no other choice but to buy a battery out of your own pocket. Would you be able to submit a copy of the receipt and get reimbursed? I mean, up to a reasonable amount, not $400 for some specialty battery.

I do believe I have read of such compensation for purchased batteries before.

I'm very accustomed to squeezing the life out of batteries and confident that I will catch it long before it leaves me stranded. The cold weather weeds them out pretty fast.

Maybe, I'll quiz the Mopar service people during my next visit and ask how dead is necessary for a warranty replacement.

I'll just buy an oversized AGM from Costco whenever the battery starts to work too hard for cold starts. Keep the new AGM inside until the Mopar is failing and then call my dealer. Hopefully, they'll allow me to just drop off the old Mopar POS and get a new POS which I can keep for my sump pump backup.

Sounds like a plan to me.
