And not all batteries are at full capacity when you first take delivery of the car. I had to charge mine for approx. 5 hrs. before it reached full charge. I test mine on a regular basis with a voltmeter.

Interesting, I replaced my battery about 2 weeks ago with aftermarket battery. So far no problems. BTW, the battery that I installed didn't come with vented tube, can I return the battery?

I don't think it's suppose to come with the vent tube. It should already be in your car. Also AGM batteries don't require the vent tube.....at least the Braille AGM I just got doesn't.

After your explanation I have come up with the following:

Batteries replaced with the same spec and type only need an adaptation reset.

Batteries with different spec or type need registration.

As far as the Bav Tech scan tool goes. I don't think the registration will do much. I guess I'll find out in a couple weeks when I'm back. However, I have been reading the command doesn't prompt for any input so....I may have to end going to dealer. No actually to an indy. Screw the dealer.

The adaptation however, should reset the charging program for the battery. Say you have an old battery that is not able to hold a full charge. Your car will detect this and "under" charge the battery to put less strain on the alternator.

Again this is theory and not official. But I think this is how it goes.

Even if you are replacing the battery with the same one, you still need to register. Also your OEM battery is not an Agm. Is it white? If so its not and you most definetely need to register the battery change putting an AGM in.

Yes. It's white. Are AGM batteries a different color?

[Randall41]

As for the battery exploding, it sounds like it wasn't vented properly and a spark or other source of ignition occurred igniting the fumes. I have seen this several times with trunk mounted batteries.
Did you smoke any instruments or other electronics?

[Juiced46]

BMW AGM batteries are black. The white ones are lead acid.

Good to know. Thanks.

Regradless, I intend on registering it. I just don't know (right now) if the BT tool will allow me to register it properly.

[bumere90]

so If I had the white one, do I have to register it or not?

[Spitfirocks]

Dont waste your money registering your batteries. Its not worth it. "battery exploding" is not normal. It is not because he didnt register it. BMW is not even allowed to do that.

Pay us or your car will blow up. Sorry, thats not gonna happen

[bumere90]

I heard electronics go act crazy if you don't register the battery during the certain period of time. It may not blow, however the battery may drain and or mess up electronics.

It's recommended to register any battery, AGM or not.

Do you have any evidence to back your statement? We've talked about alot of reasons why it's beneficial to register the battery.

Also I heard of this explosion occurring in 2 cases here on the forum....both members didn't register the battery.....

[bily]

Between the battery, wires, and bumper you should talk to ur agent. Don't mention specifics on amps.

How hard did the cruiser hit ur car? Was it one of those battering rams?

They do. It's called "battery registration".

Stupid question: what does AGM stand for?

AGM (Absorption Glass Mat) sealed battery technology was originally developed in 1985 for military aircraft where power, weight, safety, and reliability were paramount considerations.

AGM battery technology has continued to develop and offer improvements over other sealed battery technologies. AGM technology has become the next step in the evolution of both starting and deep cycle sealed batteries for marine, RV, and aviation applications. This "next generation" technology delivers increased safety, performance, and service life over all other existing sealed battery types, including gel technology.

In AGM sealed batteries, the acid is absorbed between the plates and immobilized by a very fine fiberglass mat. No silica gel is necessary. This glass mat absorbs and immobilizes the acid while still keeping the acid available to the plates. This allows a fast reaction between acid and plate material.

The AGM battery has an extremely low internal electrical resistance. This, combined with faster acid migration, allows the AGM batteries to deliver and absorb higher rates of amperage than other sealed batteries during discharging and charging. In addition, AGM technology batteries can be charged at normal lead-acid regulated charging voltages, therefore, it is not necessary to recalibrate charging systems or purchase special chargers.

DC Battery Specialists is currently distributing LIFELINE and OPTIMA AGM technology batteries. We have replaced our gel lines by upgrading to AGM technology batteries.

this is not my write up.

Thanks for the info. BMW batteries arent AGM are they?

LOL you are an idiot. BMW is not allowed to do what? Thats not BMWs reason for registering a battery, its not to get money from their customers. But I dont know what Im talking about, and obviously with a comment like that, you know all. Do you work on these cars day in and day out?? His battery blowing up most likely doesnt have anything to do with registering it. However it all depends on what type of battery he installed. Was it the same type? same capacity? What brand? Was it vented? Did he hook the vent tube up if so? Was his IBS cable corroded to shit? Was there a loose connection? There is so much that can contribute to this guys issue.

It is totally a waste and against a lean process, "having" to bother about something that competitors don't. I call it inefficient.

BMW's attitude to impose stuff that we didn't ask just screws their reputation for reliability. It has to be easily serviceable with no special knowledge for things so common. They have to think leaner and more efficient, instead of focusing on selfish techno-orgasms that has limited or NO value to the end user, much less to driving experience.

They need the same lean consultants who revolutionized Porsche 10-15 years. They just seem to design in the opposite direction.
