This website says that
Ryobi +One 18V Lithium Ion battery packs 130501002
have Sanyo made Lithium 18650 size cells inside.

Can anyone confirm that Ryobi uses the Sanyo made Li cells?

Panasonic bought Sanyo a few years ago,
sold the Japanese Eneloop NiMH battery factories to Fujitsu,
and built new factories for battery production in China.

Milwaukee M12 uses the more expensive Samsung Korean made Li 18650 size cells,
and I assume the Milwaukee M18 uses Samsung too.

Since Techtronix owns
Ryobi, Milwaukee and Rigid (Orange body color)
I wonder what Li ion cells are inside Rigid battery packs?
