Not quite the same model, but I use an X230 (2013 model) as my primary machine at the moment (not counting the company-provided machine I use for work). It’s still a really nice machine, easy to service, and they’re dirt cheap on eBay!

Any recommendations for a new battery for the X230?

Honestly, mostly I'll buy Lenovo-branded batteries on eBay for these things and hope they're new old stock and not counterfeit (or are at least high quality regardless). That is the biggest worry I have about using older laptops though; spec-wise, an old used laptop can honestly be just fine for a lot of people, myself included.

I'm glad hobbyist projects like this exist, but I wish they didn't have to.
