Does anybody know of a source for these? The original Lenovo stock is getting pretty old to be useful.

Try looking for 70++ batteries (which replaced 55++). They are going to be a bit fresher, although I am not sure new ones are still being manufactured.

There will always be plenty of eBay sellers selling non-genuine (compatible) batteries; you can ask them which cells they use.
Current: Thinkpad 25 (20K7), Yoga 14 (20FY), X220 4291-4BG, T410 2537-R46, T60 2007-QPG, T42 2373-F7G
Collectibles: T430s (IPS FHD + Classic Keyboard), X32 (IPS Screen)
Retired: X61 7673-V2V, T60 1952-F76, A31p w/ Ultrabay Numpad

The 70++ that I bought in November 2016 from Amazon.de was manufactured March 2016.
