It makes more sense if you read the context. They're responding to a comment that said this:

I guess you don't understand active cooling then. If the coolest air in front of you is ~160⁰F, well that's the coolest your batteries are gonna get, at best. Which is way hotter than rated temperatures for lithium batteries...

A response that says "it's not X" can be interpreted as "it's not doing the thing you said it's doing". In this case, over_clox is saying that heat transfers directly from the battery to the air.

Last I checked, my fridge works even when the room is warmer than the fridge.

Compressor heats up coolant, coolant exchanges heat with outside, cools down then evaporator cools it further, heat exchanges with cold loop then goes to be compressed again. It's the same principle that freezers and ac use, with the phase changes of the coolant you force them to move thermal energy in the desired direction.

Yes, and it cools stuff to cooler than the outside air, right?
