K'. Why not put a Briggs and Stratton in it instead of a Hemi, while they're at it?
Why cheap out on critical power item?
I don't get it. I mean, they put an AAM all gear torsen axle on the thing. $20 more copper is a profit breaker after that?
pppfffttt

Not much differant then the bean counters squashing the engineers on using a billet cam,instead of a cast cam,lol.
If the engineers had free rein on building the vehicles,they'd have a good product,it might cost another 500 bucks though

Look at my engineering quote for the Neon. The power window option for the sedan only put power windows to the driver and passenger, the rear occupants still had manual roll-ups. Somebody probably got a big bonus for that cost-cutting move.

At least they had rear windows that would go up and down,the rear windows in a Challenger are fixed,lol

Thats a problem for the rear seat occupants. That would never be me, so it would never be my problem. If my passengers don't like it, they can walk.

add an extra $20 per vehicle adds up quick at scale. It's nothing for an assembly line to crank out 1000 vehicles a day, over the course of a year the extra cost is in the millions. I've heard of when part costs change by a few cents that the bean counters get angry.
As for differential used, an HD truck is more likely used for heavy work, a clutch type will more likely fail when abused verses a gear type. Less likely to have warranty replacement of the gear type and the initial cost difference between the two types is negligible.

Walmart AGM batteries, an H8 for $135, with a 4 year replacement… I can’t imagine why you wouldn’t. You get on these forums and folks with crazy random power issues, all have the lead acid factory batteries. I can’t say I’ve seen anyone with AGM posting up issues with them. They deliver current better, they don’t corrode, they aren’t anymore expensive and generally deliver more cold cranking amps. When it came time to replace my factory H7 I just popped the plastic piece out of the battery tray and put in an H8. Now I sit at stoplights probably twice the amount of time before Etorque kicks the motor back on. Usually, it kicks the motor on because the heater core is cooling off and there’s a demand for more heat in the cab.

When I replaced my battery I did AGM H7 maximum Cca I could get from Duralast Premium Battery. Works for me did not need H8. Most issues here r heat not cold. But if I was in cold climate would do H8.

Anybody with experience differences in AGM quality between manufacturers?

There's only a couple of manufacturers left -
Clarios (formerly Johnson Controls, now made in Mexico, all sorts of brands),
East Penn (made in USA, Duracell, Dekos, etc),
Enersys, made in USA, Odyssey, Northern, X2), Optima?

btw, Interstate is a spec & bid outfit that is just a brand that bids out to low bidders based on what region of USA you're in, including foreign nations. Yeah, I know Costco carries them, but different locations have different manufactured batteries. Doesn't sound like a quality placeholder company to me.

East Penn FTW.

HEMIMANN · Feb 11, 2024

So I mic'd the battery negative lead to the truck frame. O.D. with insulation is 0.775 inches. Um, according to these guys it's a 4/0 A.W.G. cable size. I'm good?

Remember, I got a Heavy Duty Ram 2500. MY2017

You could still upgrade or add another couple of grounds to it.A gound to the engine, one to the frame,and one from the frame to the box wouldn't hurt , it's pretty easy to piggyback another 4G from the alternator to the fuse box if you do want to upgrade it a bit.

Ha - you read my mind. When I saw the B- lead go right to the frame, I started thinking uh-oh!

It was in the garage and dark, I can't see over the high body side. And so, another spring project is born. If they didn't ground B- right to solenoid also, imma add that.

I'd have to look at the alt wiring to see where it's going now. Thought alts usually tie to B+ and block gnd?

Sometimes think like the new trucks. Luck of the draw. I did my H7 a year ago, Feb 2023. But it replaced the same battery that went south with only 3 months on the ole age meter. On replacement got educated by lead mechanic at dealership ref IBS module also.

Your right,i went from the alternator to battery,then from the battery positive to the fuse box,been 10 years since i did the upgrade,and i'd forgot i went from alternator to battery first

What is IBS Module, Boird?

Intelligent Battery Sensor

Well I'll be damned. I learned something today.
I'd assumed they would have integrated such a thing into the ECM instead of an add-on.

Did your IBS fail, or didn't you have one?
What model year?

turkeybird56 · Feb 12, 2024

Definitely has IBS, 2019 5th Gen 1500 Bighorn. NO not fail, but when the original battery was replaced with the 1st AGM, I had no knowledge of what/whateva the IBS done, so the charging rate was incorrect for the new battery. Did it kill it: doubt it. But with the new info: I was able to learn about it and "reset" it. Funny how sometimes U neva know about stuff till afta the fact: hate dat chit.

Hi, I have a 2016 6.7 cummins and need to replace batteries.
What are your guy's opinions on agm vs OEM vs lead cell?

I have heard that agm may not be the best for a stock alternators. Is there truth to this?

I am open to opinion and what you all think. Any input would be greatly appreciated. Thank you guys.

AGM for my hemi, lithium for the motorcycles where weight matters. The Walmart AGM is not that bad $$$.
