So I did a bit more searching as to why that battery has those style posts when every other battery does not... turns out what you have is a motorcycle battery! and motorcycles that I've worked on always have ring terminals that get bolted on so studs in that case are what you want, otherwise motorcycle batteries have a weird little flat lead tab with a bolt hole for a 6mm bolt!
So not only do you need a post to connect up to, but the studs that are there have the battery case close enough that once you have a post on there the cable end is not going to have any space to clamp on, so you need a spacer as well and of course you need everything to be a nice tight fit because when you crank the starter over you are drawing 100's of amps and a bad connection will melt.

Ugh. I wish I had selected the PC680 battery. The adapters just bolt-on to that one. Easily done. Well, anyway, I sorta doubled-down since I have this battery in hand. I ordered the SAE post adapters I chose from the link you posted. I chose the pair that seems to have a built in spacer at the bottom, unlike the other ones on the list. I'm hoping that these hex-bolts are meant to fit into the adapters to secure the unit. That would mean the adapter is threated on the inside and might fit onto my M6 posts. Maybe. I'll keep this thread "posted" (pun) as to my success/failure. Maybe it'll help someone else!
