My BMW parts department told me that there are 3 batteries listed for my E91 priced $179-$269 before the CCA discount and they are all in stock. The one currently in the car is a BMW branded Exide battery PN 61217586962 (I just checked). It looks like a squeeze back there, so I'm not surprised if some non-BMW branded batteries will not fit.

If your battery is 7 years old, congratulations! But I'd probably go ahead and replace it, because when a battery fails completely it's usually at exactly the wrong time in exactly the wrong place.

I don't think the Euro car engineers have come to terms with the possibility that a typical household in their US buyer demographic may have 5 cars and they may not be driven every day. As others have said, if I wanted to plug my cars into a wall outlet every day, I would have bought a Nissan Leaf.

Interesting that on the Japanese cars the batteries are no big deal. They fail like clockwork every 4 years, there are four 10mm nuts to undo (no 7-page DIYs on changing the battery on the Toyota board!), the dealers keep them in stock and the whole escapade takes about an hour of time, total, and costs about $100. It's not rocket science except on a German car.

Why make anything simple when you can make it complicated?
