Just got a pack of heaters like that, which is a first for non-Sanyo cell for me.
They came from a Lenovo L08P6D11, 11.1V, 5200mAh pack, at 3.5V.
Were charging just fine up to voltage limit, current started to drop a bit, then for some the voltage sagged and they went back into CC and started heating up, while the others just heated up in CV while slowly dropping current.

Graph of the charge attempt:

I just experienced similar issues , testing with a liitokala charger, voltage won't go beyond 4.05 / 4.06V , they get hot.

I have a set of 9 cells from a Lenovo package never used since 2011. Basically, the battery was sealed when I received it. All cells have over 2550 mah, even 2650 mah. They did not heat up at all loaded with liitokala 500ii at 300 mah. I thought not to force them considering that they have not been used for 9 years.
