non-recycled. These were bought new

Sorry about not getting the part number, hard to see even with a flashlight and my eyes

Are these considered "heaters"?

Nope they are Panasonic NCR chemistry cells Panasonic purchased Sanyo in 2009
The just haven't changed labeling and insulator sleeve colors. (Don't know why)

However any Li-Ion cell can become a heater and for some reason Sanyo is taking the brunt of the blame.
I believe one of those reasons is that Sanyo cells were used in a lot and I mean millions of battery packs.
They where designed with a reasonable cycle life 400 to 500 cycles. After that they where supposed to be
properly disposed of. Unbeknownst to Sanyo though when the BMS on the Battery Pack said "get a new Battery"
there batteries where discarded and entered into the DIY recovery stream.
Some of these batteries when charged became known to be heaters as their temperature would exceed what we felt was excessive.
Rightly so as they where beyond their life expectancy. Any one with a proper IR tester could have determined that the cell was out of spec
and should be discarded into the proper disposal channel.. Why waste your time testing a cell that is no good.
I have charged literally hundreds of Sanyo cells of all capacity's, BTW a true Sanyo call Starts with UR18650...,
and by adhering to strict min V and max IR values have never encountered a heater using this method
