The way I'm interpreting this lately is there is good, and then there is Diesel good.

Diesel's tend to have a deep draw during the start, and what the standard CCA good to go rating is doesn't really work. I'm starting to look more at the resistance values when testing batteries rather than the CCA. High resistance does allow the flow of current as readily and why we may be seeing a higher voltage drop than what would be ex[ected going by the common go/no go CCA percentage of a new battery.

I think you made a good audible.

 

Subscribing....

I purchased a set of the Advance Gold 5yrs ago to the day and they are still holding up great BUT I know I'm running on borrowed time!! I've been looking around for a month now knowing it's time to replace them soon. I put a set of Motorcraft in my 97 F350 7.3 last year and have been pleased so far. I get 30% off at my local dealership since I have a fleet account so I might try the Motorcraft in my 06 F350 this time....?

 

I have not been impressed with the Motorcraft batteries from the dealerships. The ones that came with the truck new were great. Dealership batteries, not so much.

 

Man, yours are lasting way longer than any I’ve gotten from them. Got my last set replaced under warranty by them after 34 months. Those batteries are now 30 months old and they’re starting to go 😬

 

I can't seem to get a set of batteries to last longer than 3 years and that's pushing it. The passenger side always fails first.

I've run the green top interstates and now have the commercial series interstates in the pickup.

 

Chris, what have you done with battery cables?

 

Do you ever swap them around?

 

Not a dang thing LOL

I do have an alternator that puts out a reasonable voltage through.

 

So just stock cables then?

 

Jack, so you're just testing resistance between the positive and negative battery posts? What kind of values are you finding?

 

Not with a voltmeter, with my battery tester. Let me go find the thread.

 

Here’s showing what I did back then.

I remember that thread - good stuff. Thanks for the refresher. Unfortunately, I don't think my older style Solar tester measures resistance, but I don't see why it would be any different than using a multi-meter.

 

Nope.

Sears sold their brand name "DieHard" to Advanced Auto for 200 million dollars last year. USA Today: Advanced Auto Parts Acquires DieHard Battery Brand From Sears

Autozone is selling Diehard Platinum batteries in brand name only. The AGM batteries that Advance Auto Parts is selling under the Diehard Platinum brand are NOT "the old Sears Diehard Platinums" that used to be made by EnerSys and as such, used to identical to the Odyssey PC-1750T. The current Diehard Platinum batteries sold today at Sears and across 4,800 Advance Auto Parts and CarQuest retail outlets are NOT at all the same old Platinum, and do not have the same specifications, build quality, or energy storage capacity.

Here are some specifications for our Group 65 battery size in the NEW (and not as good) Diehard Platinum AGM battery:

Specifications
Amp Hour: 68.0 AH
BCI Group Size: 65
Cold Cranking Amperage: 750 A
Cranking Amperage: 935 A
Reserve Capacity: 120 min
Weight: 42.5 lb

It is no secret that Sears is closing, with hedge fund leadership scrambling to pocket any residual value remaining in what was once America's most popular brand names. Having already sold off its Craftsman brand name to Stanley Black and Decker for $900 million dollars a couple of years prior, at the end of last year, Sears likewise sold the DieHard brand for $200 million.

Why anyone would pay 9 figures for a 7 letter name is precisely illustrated by the quote which this post is responding to. Most people see the brand name and think, "oh, it's back" and buy it based on the formidable reputation of the former product.

But this battery isn't that product.

 

Well, good to know. Caveat Emptor .....
