Batteries

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

I wonder how many people know that trick ?

Kaz 01-23-2004 09:22 AM

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.

Looks like they offer one for the E46. 70AH. 61 21 6 924 021.
Will post some more info later if I get a chance.

Interesting info, good at the same time to anyone that will have to get a replacement in the future, Thanks for sharing the info Ron

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...

It's on the things to do list.

I come up with two part numbers for AGM batteries.

61 21 6 924 021 70Ah, 20.67 kg = 45.57 lb.
61 21 6 924 023 90Ah, 27.25 kg = 60.08 lb.

Anyone know what size battery is used in the E46 and Z4? Group 91, 93 etc.

Kaz 01-23-2004 11:50 PM

My E46 has a BCI Group 94R, 80Ah battery.

Neither of the above numbers are in the NA system. Parts guy says the new 7's are coming with the 093 one. Will try to add to the system and get availabilty and pricing.
Not sure how to figure out what size they are. May have to go look at the dealer.
Supposedly in the NA E46 touring and new seven series.

BMW AGM update
 
Talked with Paul today. The 70AH AGM battery 61 21 6 924 021 is now in the system.
$247 retail. $148 net. There are none in NA and 111 in AG.
He assumes that he can order one but since he can't ship regular batteries, he's not sure if he can ship the AGM ones. He said he would check with NA on this.
Since the Z3 stock 738 battery is also used in the E46, I assume that the E46 AGM size is similar.
I'll compare the 738 one to a 2001 E46 325i one soon. If anyone can measure the one in their E46 it would help.

By any chance do you live someplace hot? :)

Seriously, take a gander at this map of battery life expectancies. Batteries usually die from the summers not winters.

hmm, I didn't know that :dunno: I knew I read these things for some reason! :thumbup:

Well, I only learned this recently from a fellow with the ADAC (German motor club) road service and northern Europe is quite temperate compared to the American south! (30 C / 86 F is considered a hot day.)

Kaz 09-19-2004 01:54 AM

High temps seem to be bad for pretty much all types of batteries, though cold temps tend to put a greater load on them, since engines are harder to turn over, and more 'stuff' is being run.

Interestingly, it doesn't seem to me like BMW batteries mounted in the trunk/under rear seat last much longer than Japanese/US ones mounted in the engine compartment. Considering how crappy the euro (mostly Varta) alkalines and lithiums I've used for non-car stuff, maybe euro batts just suck.

Could this be because most of the time the engine is off?

Pinecone 09-19-2004 03:38 AM

over 2 years, that's not bad. The battery in our E46 M3 lasted 2.5 MONTHS.

I hope your car batteries aren't following the trend of PCs turning into mush. <-- WARNING: link contains indirect Mac propaganda. :)

True, windows stinks

johnf 09-19-2004 09:52 AM

I have trouble understanding Microsoft Windows, but that could just be me. Although the viruses floating around are sterile on a Mac, Mac owners still have to clean the junk out of their inboxes. I liked what that fellow wrote to relieve his frustration.

I also meant to finish that post. Two and half months is a rather short life for a battery. Pinecone was there some parasitic drain (analogous to a virus on a PC) running down the battery and shortening its life?

Pinecone 09-20-2004 05:38 AM

No, current battery has been fine for over 3 years. That quick is most likely infant mortality, basis bad battery to start.

But BMW factory battiers are generally junk compared to others out there, and that is why so many change out fo Optima or Intersate or other.

Mpire 09-20-2004 06:21 AM

Well, I wouldnt mind having an optima or whatever, but I just dont like the idea of paying for it.

phrider 06-09-2006 05:28 PM

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)?
