I can still buy genuine Lenovo batteries for my Thinkpad T440p from 2014. Yes, they are not cheap (the 9cell battery cost ~140EUR in Germany). I did consider switching the cells myself, but given that a good 18650 costs around 7-8EUR, and all the work involved, I don't think it's worth it. EDIT: I see now that all current Thinkpads have integrated batteries. What a shame. One more reason to keep my T440p alive as long as possible...
