How quickly should you register the new battery? Is it okay to drive around like that for a month?

I replaced the battery with the same specs. I don't have any OBD adapters / cables, which is why I am waiting for their arrival. Kinda wanna save those 50 bucks just for an easy registration that can be done with free apps.

In my '07, I waited for years before registering the battery.
In the 2010 I had last year, I registered the battery about 3 months after another shop had swapped it.

I wouldn't worry too much, the registration isn't going to save or destroy the battery, it will just make it last longer.

It is *extremely* unlikely that the battery explosion this poster encountered is because he didn't register the battery, or because he used a non-OEM battery. It is much more likely that the battery he bought was defective.

Traditional lead-acid explosions don't happen because of charging too fast or too slow, they happen because the gases that come off of a charging battery contain hydrogen, and a spark plus hydrogen equals boom. My guess is that the battery was defective or drained significantly, and the little battery vent hose had come off the side of the battery or had come off the side of the battery well and it was just venting into the battery compartment.

What else is in the battery compartment? A bunch of relays.
What happens inside relays? Tiny sparks.

Depends. If your battery is insanely old, the car will command more amps and volts to charge the battery. Usually it does a good job recognizing charge and will prevent an overcharge. You can actually go into the IBS using inpa and see your overall battery status

Unfortunately you got stung and learned first hand what can happen when a battery is not charged properly. Registering the battery is about telling the charger what kind of battery is installed (wet, AGM,etc), and what stage of life the battery is in so that overcharging does not occur.

I am getting an error message stating:
Battery could not be replaced.
Possible cause(s) of fault>
-No communication with IBS or engine electronics.
-DME/DDE program status cannot save battery change
My car died after work. I stopped by a store and came back out and it would not crank.
I purchased a lead battery from Walmart that matches the same specs as the original battery.
The car will not start even after replacing the battery so I am not sure if it is because it needs to be registered.
I have tried several times to register the new battery but cannot get past this error message.

Registration has nothing to do with whether or not it will start/crank with a new fully charged battery.

I would worry about that later. Your starter most likely died, they are known for cranking slower at first and then suddenly nothing.

[vilord]

Although, if there is no communication with DME, that would also keep it from cranking. IBS is attached to the negative battery terminal, you can unplug it and the car will still start (my 07 had the IBS disconnected for 4 years)

This happened for two reasons. The battery was obviously being overcharged by the computer and 2 because it wasn't able to release the built up pressure inside the battery through its vents likely because they were clogged.

The battery wont necessarily be "destroyed"

The terminal connectors have a pyrotechnic device that goes off

Either way youre stranded.


The Germans are still getting even with us for losing the war.

[vilord]

The 'pyrotechnic device' in the terminal is triggered when the airbag goes off (I know, I was in an airbag-triggering wreck last month).

Are you implying that it will trigger the battery disconnect because you didn't register the battery??

You can remove enough plastic to physically make the connection after the pyro has blown. Body shops do this all the time

If the ibs is always measuring the batteries state of charge and SoH every few hours and updating its info, what does registering it do? If it sends charging rates based on the info it gets on charge and health state of battery, why does registering really matter, are there override functions that takeover because it thinks you have old battery? Seems silly.

Someone said the battery reg. was to document battery life @bmw

OP's battery DID NOT EXPLODE!
He writes about that later on the thread. It was just BST was triggered, the pyro device at the positive terminal that disconnects in case of an accident.

OP should have changed the title of the thread.

The battery won't explode if not registered, though..
