Hey does anyone know a good indy shop to get my Braille 21lb battery registered?

I'm located in Livingston, NJ.

I have a BT tool but unfortunately, it does not register it completely. I think it only resets the "charging program" that is learned throughout the batteries life.

Thanks.

what do you mean by registered?

and im getting braille soon

[fdriller9]

We need to register our batteries. Our cars adapt to the batteries age, spec, and type. It "learns" a charging program and adjusts to properly charge the battery. Since most non-M E9xs come with lead acid batteries the AGM Braille needs to be registered.

Well all batteries need to be registered....lead acid or AGM. Not registering a battery can result in over or under charging, which can lead to a shorten battery life or damage to the IBS sensor. In recent cases, explosion of the small charge that goes off when the car is in an accident, to disconnect the positive terminal to prevent a fire/hazard....even though the car has not been in an accident.

Sucks huh?

[NightStalker]

thats so bad lolll..esp the fire hazard

goodluck though

do you have any pics of the battery?

FYI, I just recently had to purchase a new OEM battery for my e92. A good friend of mine is a master tech at Open Road BMW Edison. He supplied the oem battery and he registered it as well. The registration has nothing to do with the "adjustment" of the car to the new battery or anything like that at all. Registration only tells the dealer where and when you had the battery changed. Thats it.
Now, in your case, going to the braile may require additional programming, not additional registration, I think people get this term and process wrong. From what I have been told by my guy and other BMW techs is that if you buy a cheaper black battery (oem is white) then programming must be done to compensate for the new type of battery. Ive heard stories of the black tops dying in a couple months but mainly because they operate differently then the white ones, IDK exactly how though.

OP I highly suggest going with an OEM sized exact replacement for your car. Are you road racing or something? Who cares about the size of the battery? Unless you are a hardcore track guy or something, I wouldnt play with changing anything having to do with the battery. BMW can flag your car for running a non improved battery and doing damage to electronics or the charging system.

Good Luck

I live in Livingston too. I'm surprised I've never seen this car around.

Probably need the ISIS tool to program it completely

Im sorry either your Tech friend has misinformed you, or you misunderstood him. You are correct on that registering tells you when the battery has been replaced. But it also resets the charging strategy, due to the battery capacity has changed. In short, depending on the capacity/state of charge of the battery, the charging system will adjust/learn accordingly. When you put a new battery in, the car doesnt know it, and can potentially overcharge the battery etc. Hence the reason for the registration process. There is a HUGE recent thread where I posted alot of info on how this operation works.

Black batteries are AGM and are most expensive than the white, lead acid batteries.

I'm not worried about being flagged. I have so many mods to my electrical system the battery is the least of my concern.

Also juiced46 has told me that ISTA asks you question about the battery....in the registration menu.

AGM or non-AGM?

Same capacity?

And some others but I don't think much programming needs to be done. Usually when you program the car, the whole car needs to be redone.....which takes a few hours. Battery registration only takes like 15-30 minutes from what I've been reading.

Correct me if I'm wrong.

I'm in Philly for 2/3 of the year. I am home now though.

I think I'm just going to have my battery registered at an indy. Just need to find one....

Where are you getting this information from? And how can the battery be over-charged? Ive talked to a load of tech at 3 dealerships and they all said the same thing. They never mentioned the charging strategy or anything like that. The only thing they ever mentioned was that accessories would shut off if your battery was dying and could not support them. It conserves juice. I really dont think that the registration is necessary, but I did it anyway just to be sure! lol

btw your cobra is fucking badass!

[e92stance]

registration took 30 mins. I had the battery replaced at my boys side shop, then taken into the dealership to register bc his labtop took a shit while he was trying to do it from his shop....

[e92stance]

Juiced46.....forget it! lol I just read in a post that you are a BMW tech and have a shop! I guess thats where you are getting the information from! lol

Hey is Wallinigford anywhere near Windsor Locks Ct? I may be moving there due to a promotion at work, looking for a good dealership and indy shop (you maybe!lol) The area I may be in is near Bradley International.

Let me know....Thanks

First off, thanks about the Cobra. Its a fun ride!

Yes I am a BMW tech. Registering/not registering the battery does indeed have an affect on charging the battery.

Without getting into crazy detail. Any BMW with an IBS cable needs the battery replaced. Basically, the DME continually adjusts the charging strategy based on the battery capacity. It basically learns and says ok the battery is only 60% charged for example, its going to have to bump amperage/voltage up because the battery is not at full capacity so the alternator has to charge it more.

Now when you replace a battery, obviously the charge capacity will be greater. Lets say you hook the battery up but do not register. The vehicle doesnt know right away it has a new battery. So its going to use its "learned" charging strategy from the old battery which can potentially overcharge or not charge the battery properly. Will it eventually learn it has a new battery without registering? Yes. However it can drastically shorten the life of the new battery due to it not being charged properly from the get go. You may not ever even notice, but this is one of the main reasons for registering. Also its used for diagnosis. Your tech friends are correct, depending on voltage the system will shut down non needed consumers in the event the battery charge goes low. ie heated seats, rear defrost etc etc.

This info is also straight out of BMWs electical training manuals etc. which also has a ton more info on this stuff.

If you read the "battery exploded thread" in the E90 forum, there is alot of info I posted about this stuff in there as well. Its a long thread with alot of BS inbetween, but there is some good info if you have time to read 14 page lol

Windsor locks is about 40 mins north of Wallingford, not to far. Let me know if you make the move!

Thanks man, appreciate the information!!!!! And if I do relocate, I will contact you for some services!!!!

[fdriller9]

I found a shop that was able to program and register my battery.

Pinnacle Motor Werks in Stirling, NJ.

Read my experience here: http://www.e90post.com/forums/showthread.php?t=473109

Not really about the indy but more about the whole programming/battery registration procedure.
