There seems to be a myriad of 18V/20V battery systems out there but no resources to determine their interoperability.
I'm trying to compile a list of systems to help buyers choose tools and batteries.
I've omitted the higher end systems for now because I assume they are a close silo and are designed not to be interoperable.
Corrections, additions and modifications are welcome. Let me know in the comments.
Note: The aim is not to see which system is better - because that deserves its own thread (maybe) :)
but merely to see which tools works with which battery.

Speaking of Xfinity Plus, I bought some Xfinity Ultra 21700s on sale at Aldi the other day. They are longer than my old 4Ah Plus ones (though slimmer, presumably because the old ones had more 18650s), and don't click securely into my Gardenline mower or polesaw.
They are still pin-compatible, but they work their way out with vibration during use. Quite annoying to have batteries which are so close to fitting but ultimately not right.
There's an email address on the batteries so I've asked if the old shape can still be acquired, but don't hold out much hope. Seems wasteful.
