I changed my battery by myself with one that is OEM spec, well over a year ago, and Knock on wood(now that i said it, its gonna happen-___-) I am in the clear.
I have a feeling this issue isnt related to programming your battery. If anything when you put in a new battery, it gets UNDERcharged because it knows the old battery wasnt capable of holding enough charge. I did plenty and plenty of research on this matter and even asked my old SA. Its just to "get the absolute most out of your battery." But for $280 (which is what my local dealer asks just to program it) I can buy 2 more brand new batteries. Sooo....Im good |

There is also the option of a refund for the battery from Napa.

Here's another possibility -- did you get a non-sealed battery? If so, there needs to be a vent to remove H2 gas generated during charging. Sounds like you may have had a hydrogen explosion.
The only way to blow up a battery directly by charging it is to MASSIVELY overcharge the battery. Unless your charging system went haywire (always possible) it is very unlikely that you could have pumped enough charge into that battery in a short drive to overcharge it to the point of explosion. My vote is "battery in unvented location, no vent, H2 buildup, BOOM!" |

^Our cars have an explosive charge on the positive terminal to disconnect the battery in the event of an accident....though OP wasn't in an accident.
Our cars have this vent tube....I think. |

I'd really be worried about the acid leakage into the rear quarter panel. The acid will eat though the bottom of the battery well in no time. I hope the shop is flushing and neutralizing the acid that has collected in the bottom of the fender well. I see major rust issues down the road. |

The amount of charge a battery can hold will decline over time. The amount of time it takes to reach a full charge will also increase as efficiency decreases. Your car accommodates for this. You need to register a new battery so it doesn't overcharge it.
Hence the thread a couple months ago from another member who decided to not have it done, and had his battery explode. |

Oh I plan on doing this. I still have the receipt and I'll have the old battery. I'm also going to have the mechanic jot down a note explaining what happened so i can present it in hopes of getting a refund.

The mechanic said this very thing himself. He asked me if i hit any big potholes or bumped into anything prior to the explosion which i did not.

I totally agree with you being as pissed as you are.
We're talking about a BMW here. A BMW. This is not a Chevy Beretta for crying out loud. I'd drive the thing through a dealership window. |

The little black book in your trunk obviously states that the battery must be recoded. Sure, it may not explode if you dont, but it just might. |

Even minor things like changing a battery make you think twice. I can't believe I even went to a dealership to put air in my tires after I got a low tire alert for fear of doing something "wrong" myself and voiding some clause in a warranty. BMW, sadly, sends a clear message that their target market should be people for whom money is no object. Its a disgrace. |

A battery change should not cost $300, I don't care how sophisticated the car or battery.
I suspect this has nothing to do with the registering process and can likely be attributed to the battery itself. The registration process, as stated above, is there to lengthen the life of a new battery. Not doing it might shorten the battery life but certainly should not cause a battery to explode.
