Removing Battery for Winter
My M2 will be stored for a few months as I holiday abroad for winter. I plan to remove the battery and store it in a temperature controlled environment.
Just wondering if I can expect any grief when I re-install the battery? Will the vehicle remember all its settings? I hope I don't have to go through a reprogramming session when I re-install the battery. |

Why not get a battery tender?

I have heard that BMWs don't like batteries pulled and putting one back in requires the dealer...I'd double check with the dealer. My friend's experience was with an E92 M3 though.

Don’t you live in Richmond? What winter are you speaking of?
A battery tender will be enough with the battery in the car because of the alarm and telematics… otherwise nothing would be needed. |

That's certainly an option. As I would hardwire a tender, I would still prefer to disconnect the battery during the installation. Again, any issues to anticipate when reconnecting the car battery? |

Thank you.... I did see that before.
But again, if I proceed to hardwire my tender, I would prefer to disconnect the battery for a short period while I complete the wiring. Has anyone disconnected their M2 battery? Are there any considerations to be aware of when re-terminating? I am aware that a NEW battery needs to be registered....with hope, that wont be necessary for this procedure. |

Just make sure you don’t close the trunk, or at least, fold the back seats. |

Registration is only required for a new battery, you don't need to (nor should you) do that when reconnecting your battery. |

If that's the entire impact of pulling a battery, we're good! |

Just don’t leave it unplugged while you travel. Think of it as a battery swap. You need to unplug it and everything is fine after that. |

I trust the service clock will resume when the battery is reconnected? |

That would be correct, would only be a problem if you are pulling the battery for the winter. You may end up with having to do things such as resyncing the window pinch setting, though.

The tender leads will be terminated in the engine compartment. Of course the negative lead will terminate at chassis ground, and the positive lead will terminate at the 'hot' jumper terminal. The 'hot' positive jumper terminal is in close proximity to metal components (cross brace). And although I have a steady hand, I would rather not risk a short to chassis when I remove the jumper stud when I secure the tender lead. Safety first |

The risk lies with the spanner on the jumper stud. When in contact, the entire spanner is conductive and a potential short path. You'll have to clarify how removing the negative battery lead in the trunk risks a short? Last edited by Trogster; 10-30-2023 at 09:55 PM.. |
