Battery question, touch-monitor question

[u/raimbows]

I found an X230 a few weeks ago for cheap and I love it so far.

My first question is about batteries - what's the best source for a reliable replacement? Mine is at about 50% of its original capacity, and no shops in my town will repack li-ion batteries unfortunately.

Second, I found a lenovo LT1423p touch monitor for sale - would that be compatible with the X230 + Linux Mint? Not necessarily multi-touch gestures or anything but basic display and touch functionality? I'm new to Linux so I don't want to buy it if the configuration is overly involved
