Battery registration

Un peu d'espoir de comprendre le système. Vous avez été prévenu.

J'ai donc installé une nouvelle batterie, je l'ai enregistrée avec l'application Carly et on me dit que ce n'est pas bon. Ok donc j'ai essayé de l'enregistrer avec mon scanner foxwell et jusqu'à présent cela n'a pas fonctionné non plus.

De ce que les gens disent, l'enregistrement de la batterie est un must. Mais pourquoi ? Parce que si vous ne le faites pas, cela va ruiner l'électronique. Ok, quelle électronique peut être ruinée et pourquoi / comment?

a n'a aucun sens pour moi. BMW a conçu une voiture qui va autodétruire les composants si vous ne lui dites pas quel type de batterie est dans la voiture? Un ordinateur ne devrait-il pas indiquer à la voiture l'ampérage / volts de la batterie et l'alternateur continuera à le charger sur lesdits amplis ou volts? Est-ce que tous les composants n'auraient pas, je ne connais pas de résistances ou de condensateurs ou de micro-ordinateurs qui leur disent de fonctionner seulement si la puissance requise répond aux exigences prédéterminées? N'y a-t-il pas de fail safes ? La voiture va boiter si un petit éclat est usé hors d'un engrenage dans l'actionneur de gaz, mais si la batterie n'est pas enregistrée je joue avec le feu?

Qui a connu des problèmes ou a la preuve que de mauvaises choses peuvent se produire si la batterie n'est pas enregistrée et comment pouvez-vous le retracer à la batterie.

J'ai eu toutes sortes de problèmes électriques avec ma voiture et la dernière batterie a été enregistrée par BMW, ce qui m'a laissé penser que l'électronique échouerait parce que c'est ce qu'ils font.

Vous avez besoin d'un enregistrement approprié afin que vous puissiez réinitialiser les adaptations de charge pour la nouvelle batterie. Si vous ne le faites pas, vous finirez par obtenir des erreurs de décharge de batterie accrues et plus tard, des gremlins électriques aléatoires.

You need a proper registration so that you can reset charging adaptations for the new battery. If you don't, you'll end up eventually getting increased battery discharge errors and later on, random electrical gremlins.

This doesn't answer my question, pretty much the same story that everyone repeats. Not trying to be a dick but everyone says it's bad but no one can prove how/why.

A normal car alternator constantly charges the battery of said normal car. And you wouldn't be out of line to get 4-5 years out of the battery in the normal car.

From what I understand the BMW alternator runs intermittently in an attempt to not change a battery that is already charged. The claim is that it helps gas milage, um I have a V8 M3 and can't be bothered with fuel milage and the reduced alternator running also can help make you're battery last longer. Last longer than the average 4-5 years? Well my last OEM battery in the car was registered through the dealer and it lasted 4 years.

So regarding registering the battery we are told that the DME somehow knows the condition of your battery and therefore can cycle the alternator on and off, but the alternator will also keep attempting to charge a bad battery and if you get increased discharge then it's because your battery can't hold the charge that the alternator is giving it, right?

I see absolutely no way that any electronics would or even could be affected by an unregistered battery. And regarding the battery lasting longer, not sure I buy that either. But I'm open to debate and insight.

I think it's weird too but in the time you've spent ranting you could have had a shop register it.

End rant and move on. BMW's are weird.

The electrical gremlins I speak of are the random CEL, maintenance, and other various dashboard lights that will start randomly occurring. How do I know? I had a Carly too and used it to register a new battery and it didn't work, despite the fact it stated that the operation succeeded.

I ended up buying an Autel diagnostic tool and checking the battery status only to see that it the last time a battery was registered was years ago.

I get that you are skeptical, so I'll save you time for your next rant on this: go do a forum search for battery registration issues, and you'll find plenty of threads about it. From there, make an educated decision. If you do nothing, then you might just be fine. If you register the battery, you'll also be fine. If you don't register the battery and start getting random dashboard lights, then you'll have a place to start troubleshooting from.

I "registered" with Carly and turns out it didn't work. Although I didn't have gremlins my battery died in 1.5yrs.

I tried doing it with INPA this time around. The process says successful but when I check the registration date, the old one shows up..

Good idea, just accept everything and if you can't figure it out just pay someone to do it for you.

I'm with you and what I'm curious about is why would the battery die sooner? If the car thinks it's an older battery then the alternator would charge it more frequently but again on normal cars the alternator is charging the battery nonstop.

Either way they call it the "IBS". Intelligent battery system. It seems pretty stupid to me.

Yes I did and no one can positively link any issues with the car relative to battery registration. A guess or assumption doesn't count as proof to me.

The battery dying earlier with registration makes no electrical sense, unless BMW somehow intentionally sabotaged the system if you fail to register. This would be my guess otherwise why couldn't you reset it from the vehicle like the other maintenance items?

I recently went through this as well and had the same experience (INPA reports success but doesn't log the mileage/history of the registration), check out my post here:

I ended up registering it with ISTA and now the proper registration date/mileage show up in INPA.
