BMW X1 Battery: The Part Everyone Blames First, Not Always Correctly
On the BMW X1, more non-starts get pinned on the battery than on any other single component, and that assumption is correct often enough to justify checking it first. It's not always the real cause, though, so it's worth confirming before spending money on a replacement that doesn't fix the problem.
BMW X1 Battery: What It Does
On the BMW X1, every engine start and every moment the electrical systems run without the engine turning draws on the 12V battery. Stop-start puts far more demand on that battery than older designs, given how often the engine cycles off and on — hence the need for an AGM or EFB battery instead of a standard type.

A Genuinely Important, BMW-Specific Finding Worth Knowing — BMW X1 Battery
This is genuinely important to know before replacing this battery: if your car is fitted with an intelligent battery sensor, a new battery genuinely needs to be registered with the car's computer afterward, and coded first if it differs in type or capacity from the original.
It's also genuinely worth knowing that not every car of this model necessarily has this system fitted, worth checking the negative battery terminal directly for a small sensor module clipped to the cable.
