Alright, fully charged lithium batteries.
So they are probably 4.2v batteries, since the cheaper millimeters have a bit of resistance in their cables and circuitry.
Gonna charge 4 more.
That universal charger can charge several types of batteries simultaneously.
As can be seen, it is expensive at 50 dollars, but worth every penny.
Tagging @Windows7ge because he seemed intrested.

Might be a knockoff but it's $20 on eBay.
I occasionally play with hobby electronics,18650s, voltage reducers, voltage boosters, LEDs, lazer pointers, weak burning lasers, etc.
Strapped a burning laser to a 3D printer with medium success.

@Windows7ge These are actually 11865 batteries, which from my measuring seem to be about 5mm shorter then 18650 batteries. They seem mostly compatible with 18650 housings though, and when in doubt, aluminum foil is your friend.

That was a laptop battery pack right? I wonder why they opted for those. Maybe the width of it required the use of shorter batteries.
All the batteries I've saved out of battery packs are 18650s of varying brands.

@Windows7ge My assumption would be that, keep in mind that this was a relatively recent laptop (cat destroyed it by peeing on it) so if you are mostly taking apart old laptops, it may be a recent change.
