Not sure what cells they are, but the website seems to state that they are atleast lithium ion.

Gonna see if I can design and 3d print an adapter for my porter cable tools. Hopefully the extra 4v wont fry them. Otherwise, I'll simply rip the cells out and use them for other projects. Hard to find 18650s for anywhere close to a dollar these days, assuminug that's what these are.

I posted these for guys like you who see the value and want to do some tinkering on the cheap. Once you receive them I'd love to hear about your findings.
Previously, I picked up 100 new 2500 mah 18650s for $1 each from another site, and have used about half. Theyre great for small remote IoT or arduino projects, like weather stations, or tilt hydrometers for homebrewing. But the capacity is a little low for flashlights. They'd probably be fine for recelling 20v tool packs, but if I recall the discharge capacity was a bit low. The reclaimed packs from batteryhookuyp might be fine, or they might not be. You never know how much life those cells have remaining. But these lawnmaster packs presumably pack twelve brand new 2000 mah 18650s each, coming out to 58 cents a piece. And I'd think they'd have to be rated at a high enough discharge rate to run most tools.
Once I give them a look over, if theyre still in stock, I might buy another 5.
They are spot welded into the case in such a way that you have to destroy the case to identify the cells. If I decide to go that are I will post an update.
They case is labeled "6INR19/66-2" but that looks like a generic battery pack designation.
Edit: the cells are "SunPower" INR18650-2000
So probably mediocre at best. Have not tested capacity.

But as luck would have it, on a whim my wife just happened to order five more for me! Gee, what are the odds?

Better hang on to her; she's a good 'un. Does she have a single sister? Haha
Looks like you nailed the battery type and mAH capacity. Good times.
These are essentially new. I even had to double-check the first few I tested because I had never seen internal resistance that low.
