Interesting..acid lamination. "Remove the affected battery , turn it over once and install again."

I wonder how many people know that trick ?

I'm slightly confused. It sounds like they're saying they will be (already have?) using AGM batts from the factory. I hope, then, that AGM batts will be available in the proper replacement sizes over the parts counter. AGM is what Optimas are, and being able to get one in a 100% proper size would be great.

Ron,

Will one of the AGM batteries fit the Coupe/Rdstr?

The 99 is still on its original battery, I know it's just a matter of time...

Ron,

Is there an AGM battery that's known to fit in the S54 MZ3 Roadster? If so, is it worth the trouble?

Or should I just go with the new size Interstate (MTP-H6)?

There is but BMWNA won't bring it in. The new Z4's show an AGM one but that one, part # wise, is not in my car. BMWNA has a contract with a NA company.

I would go with the MTP 91 one.

My reaction at first was "I don't need that cranking power." But on the day it dies, I will....

On Roadfly, Dane Kane mentioned a 61-21-6-924-021 AGM battery. Is this the one that's not imported to the US?

Yes. That is stock on the Z4 M except here. 021 is (70A).
The 61 21 6 924 023 (90A) is supposedly available but is larger.

Ron, I talked to exide a week or so ago. They said they are gearing up to make the AGM battery in the U.S. some time in the future. Didn't know when.

They already have the BMW ones. Jay ordered one in locally but UPS won't ship it.
Supposedly made here.

Douglas used the Varta one which they wouldn't bring into NA.

AGM part number is 61 21 7 553 952 $152r

BMW WV Exide contact is in Charleston 304-345-5616. Not sure they will deal with us.
Will be trying the CT one soon.

I'm an ex-Optima tech sales guy. Currently Optima doesn't have a size that will drop into the OE location without some sort of modification in the Z3M. During my visit to SEMA this year I ran across the Odyssey guys and they told me that they are releasing EN/DIN sizes by Spring '10. My '00 M Roady takes a group size 48 and I'm definately going in the Odyssey direction, though likely with a smaller, lighter weight model.

FYI, Odyssey and Optima were born out of the same R&D lab here in Denver, the technologies split when Gates sold them off to different companies in the early '90's. The primary difference is construction method. They are both superior to the general AGM product out there because of the pure lead, thin plate technology.

As a result of this technology not only do you get great starting current and longer key off life (slower self discharge) but also far superior hot climate life (because the alloy used corrodes at a much slower rate and the controlled venting pressures restrict out gassing).

Currently, the only EN/DIN AGM batteries available for the US market are built by Varta . . . also, for the record . . . . Interstate batteries are built by the same company that owns Varta . . . aka Johnson Controls (who also makes Autozone, Advanced Auto, Pep Boys, some O'Reilly and some CSK as well as Die Hard except Platinum which is made by Odyssey). . . . . . gotta love brand marketing.

So Varta makes the Exide AGM batteries BMW use?

as of two years ago . . . .Varta was the OE supplier to BMW. Prior to that it was company called Hoppeke (JCI bought them out, the bought Varta).

I may be wrong, but i don't believe Exide has ever been an OE supplier to BMW.

Optima is also owned by Johnson Controls. A friend of mine worked there before when a Swedish company (Gylling Optima) owned them and after Johnson Controls bought them in 2000. I interviewed one time when I was up there visiting in the late 90's, he left not too long after Johnson Controls bought them.

I got an Interstate Battery for $120 a couple days ago. 85 MONTHS OF WARRANTY! let's see BMW put that warranty on their OEM Battery.

Better read the small print on your Interstate battery warranty:
"Within 30 months of the date of original purchase, batteries with a total warranty of 85 months will be replaced free of charge (except for taxes and legislatively-imposed fees, where applicable). After the free replacement period and for the remaining number of months of designated warranty period, the original purchaser may obtain a replacement battery of similar size upon payment of a prorated charge based upon the then current published cost per month which is based on the then published List Price of the battery multiplied by the number of full months elapsed since the date of original purchase."

Well, technically that is 85 months of warranty, just not 85 months of full warranty...
