As far as I can tell it's just an insulated cover. You didn't see the topic in which someone posted an excerpt from the manual saying that the 62kwh pack has no battery warmer? We then speculated on whether it was a software device that produced a modest drain on the pack, to warm it...?

Correct, an insulated cover which is the battery heater.

I'll believe it's a warmer when I see an electrical connection directly to it. Insulation does not warm something that is cold.

Correct, people who live in CA or warmer climates who might think just placing a piece of insulation over the battery is the answer just don't understand how cold some areas of the US or even CAnada can get. If it's 0F or even sub 0 for days on end, especially if you don't drive your vehicle for several days, the battery could get dangerously cold. It might not hurt the battery if the car just sits but from things I've read, charging it or possibly even using it hard when the battery is at sub-zero temps may be detrimental to the battery.
I get it, in CA, TX, FL or many of the southern states or even warmer coastal areas of CAnada. potentially not having a proper battery heater might not be that big of a deal but for those of us blessed(and I'm being sarcastic) with sub-zero temps(not to mention the awful -20 or even worse -30F), it's a big deal and something I can't believe Nissan would drop or not make clear if it has it or not.
With my '12 and '13 Leaf there are many days in the winter when the battery heater light blinks all day long and when I go out and start it there are ZERO battery temp bars, EVs really need to be able to handle this type of weather IMO if they are to become mainstream.

Another way to look at it (which I would if I still lived in a cold winter climate) is that Nissan gives an 8-year, 100,000-mile warranty (USA, at least--I think Canada is similar) on the battery, makes no mention about not using the car in cold weather, and sells the car in locations that get cold for extended time. Therefore, I would buy the car, drive it, charge it, park it, etc. without worry and ask (demand, if necessary) Nissan to address any problems under warranty.

FWIW, my interpretation of the owner manual and service manual for my 2019 SL Plus is that the 62 kWh battery does not have a resistance heater like the older cars and the 40 kWh models.

Owners Manual SEEMS to indicate that for the battery warranty to be in effect the traction battery has to be checked before the 3 year warranty expires.... whether this is true or not, get your battery checked by the dealer several times during the first 3 years to be sure.

Agree on all points above. As we only use our Leaf as an urban corridor runabout, and Denver in general has pretty mild winters, I'm not too concerned personally - we've never even seen our temp gauge bottoming out, or for that matter, topping off. It's always been between the blue and the red intermediate lines, i.e. the middle of the range. It does live outside, as our other cars have priority in the garage.

That said, it's clear that EV's in general and the Leaf in particular need to be engineered to handle multiple days of sub-zero temps in order to be considered "mainstream" options. While I like our Leaf quite a bit, and feel it is often the subject of unfair criticism, the complete lack of any kind of battery heater would trouble me enough to not buy one if we lived in colder environs. I regard it as further evidence that it's still an early version of an EV in some sense, even with the uprated and upgraded 62kWh battery, and reworked look and feel in general.

My quest to find the battery heater was cut short due to time and running out of winter weather, but if and when I find the solution I'll be sure to post in the topic I started last year for it.

I haven't seen any particular confirmation as to why 60 vs. 62 before. Did they change how they rate it? Did they reduce the amount that's user accessible? Did they actually reduce the pack's gross capacity?

change how they rate it? no... The pack is simply different and not sure why that is unusual because Nissan has done that constantly thru out. Now, they didn't change the 24 kwh designation from 2011-12 but the capacity did increase and like that instance, this instance also included a chemistry change.
