Can someone explain to me what happens if the battery is NOT registered?
I talked to a couple guys i know at the BMW dealership, including the shop Foreman, and they all said registration is not necessary. They did however, say that it only becomes an issue when changing the specs on the battery, where the car has to be recoded to charge the new battery. |

"Registering" is the process of informing the computer that a new battery has been installed, and while failing to do that won't prevent the new battery from working, it IS good to do and CAN make a difference in how the car manages the new battery and how long the new battery lasts. Dealers will definitely overcharge on labor for registration, because if you have a coding cable and the right software the process takes all of 60 seconds. There are DIY threads on this forum showing how to do this. As for what exactly registering a battery does, the link I added at the bottom of the post shows a description of the process. Registering basically allows the computer to pull the proper amount of current from the battery and manage it properly, which it might not do if it thinks it's still dealing with an old battery. I had first-hand experience with what happens when you don't register a battery recently with my wife's car. Her Mini Cooper S's moonroof would only close completely while the engine was running; when only the ignition was on, it would come forward but wouldn't pull itself all the way down to make the seal, and it moved much more slowly overall. I suspected the battery wasn't providing enough power, so we got a new one. The indy shop didn't have access to the computer they normally used to register batteries that day, so I told them to give me the car with just the battery and I'd DIY it. I tested the moonroof with the new battery BEFORE registering, and the problem remained, which I suspected was because the computer didn't know it could now pull more current from the battery. Registered the new battery, problem solved immediately. Screenshot that describes battery registration: http://www.bimmerfest.com/forums/sho...2&postcount=18

Plan is to go to Napa and get the battery and install. Then take it to the dealer. Hopefully they wont whack me too hard for just a registration. |

There alot of scan tools that will do the registration I believe the bavarian technic cable does it. Dealer will probably charge you something ridculous.

Can this be done with the tuning cables? Like Evolve and ESS? Probably not right...

They may actually work as long as you find the software (same package that's used for coding), but I can't say for sure. Definitely worth a shot before pulling the trigger on another cable though; it'll either work fine or the software won't detect your car at all.

Just a follow up for anyone reading this.
So far the NAPA battery is fine. Put it in and went to BMW to have it registered. They may give you a hard time when registering the battery since its not OEM and they may say that the car will not allow them to register it. That is false and there is an option for them to select "other - non oem" during the registration process. Total cost for the battery 115$ |

My dealer quoted me $195 to reset battery. Dumb Stealerships.
Time to find a Plan B

My battery died shortly after I bought mine. I wish I had seen this thread. I ended up buying an interstate battery with same specs (or very close) and got it registered at the dealership. I wish I know more about coding because I would have just bought a tool to do some coding and registered the battery at the same time
