I use an x250 which has dual batteries

An internal 3 cell battery and a removable 3 cell battery (a 6 cell one is also available)

I don't have a spare but the main point of this set up is to allow hot swapping of batteries wit no shutdowns when AC is unavailable

The X270 too. And it has an USB c port as well.

X200/201, X220/230, X240/250/260, X270/280/A275/285 are each substantially different. Between slashed groups there are limited parts interchangeability e.g. battery, X250 trackpad retrofit on X240. In case that matters.
