I have potential access to a garage. I will have to make space though which will likely cost some money as in getting older. Also there a lot of crap in there. When I built the garage I had it made ready for lvl2 but my friend who is an electrician went through it and used a few bad words. WHY?! was mentioned several times. It seems to get usable lvl 2 I will have to have an electrician over again. Kinda wanting to hire my friend at this point. I don’t know if it’s possible. He’s Union which means he’s better trained and he also used to own a leaf, but hiring Union electrical work can be difficult in my area. Atm I’ve got lvl1 from the temp charger that came with the car which seems to be adequate ftm. I was afraid it wasn’t at first, but I discovered the previous owner had it set to charge only between midnight and 6am. I turned that off and it charged fully between uses.
Can you better describe what you mean by having your garage ready for Level 2? Do you have a 240V plug somewhere? If so, what is the amperage of the breaker it is connected to?

Is the "temp charger" you got with the car an original from Nissan? Does it have an adapter on the end of the plug? If so it might be capable of Level 2 charging when plugged into a 40A 240v circuit.

This is one thing I’m having trouble finding out: what chemistry are my batteries? Different chemistries have different charge needs for logevity. There was one design for example where you wanted to run the thing between 20% and 80% for best longevity. I don’t k ow if I have those batteries though.
2019 has the latest Leaf battery chemistry. Running between 20% and 80% is best practice for any EV battery but it's not an ironclad rule; the car is meant to be used. The most important thing is not to leave it 100% charged in warm weather.

That is the issue. I had a whole seperate 1000amp service put in the garage and asked the electricians to put in level 2 plugs. Basically the didn’t. They put in the breakers for them all 15 amps, and there was one actual working socket, even though it’s the smallest type and I could only find one charger on Amazon that even fit it. The other two breakers don’t even have wires coneected to them. I have a friend who is a electrician who went through the thing and was very very angry about the job done. Basically I’ve got a service that can take level2, WOULD take level3 if I could get it, but currently connects to nothing actually useful except 110. Basically I’m going to have to get another electrician in to make the thing actually useful for level2. The only bright side is I drive so very rarely and such short distances that I can actually get away with level1. It’s probably going to be thousands. Again.

L-1 can actually be more useful for keeping the battery warm, by charging the car for much longer. It will be able to stay ahead of the battery warmer's modest but real power consumption as well.

The LEAF has been fine in Canada and Norway if that makes you feel any better. I really would not worry too much. Just don't run your battery go down to 0 (ideally not below 20).

L2 is typically on a 50amp breaker, don't worry about that right now. l1 charging can actually be fine for your driving and it helps heat the battery (you should have a battery heather as well) just get a good gauge extension cord if you must, not a cheap one. This "temp charger" that comes with the car you can use forever. Based on the low amount of driving you do I am not sure I'd bother with installing a 50amp breaker and a NEMA 14-50 outlet and mounting an EVSE (all of which I did but I drive more).

On a plus vs a non plus, in your case I see no reason to get a plus just based on how far you said you drive. Even in Minnesota or even Alberta or whatever you won't need a plus with short distance driving.

Level 1 is 110v AC, Level 2 is 240v AC, Level 3 is DC fast charging.
Level 3 installations cost at least 4 figures, and no one has them at home.

If you really do have a 100A panel in your garage, it shouldn't be too hard for your friend to run a 240V circuit for you. Just the cost of wire and a new breaker.

Well not no one. Not many though. Level2 is going to cost me four figures. Again. Makes an argument for me to look into level 3 as I’m going to have to drop a chunk of change just to get level 2. My memory is level 3 is 3 phase though so it may be flat out unavailable. Even with a 1000amp service to my garage the best I may be able to do is point 50 amps of that at my car.

L3 means the EVSE is actually the charger. It converts whatever AC power it receives into the 400+V DC source that directly charges the HV battery of the car. As such, it must monitor and control the voltage and current supplied to the battery to properly charge it. There is a lot of complexity and engineering involved. These are not consumer devices.

With L1 or L2 the EVSE only supplies AC power to the and the car's on-board charger creates the high voltage DC levels and monitors the battery, etc.

I meant to say it would take five figures (not four) to install a residential Level 3 charger. So a LOT more than level 2. Which is why I’ve never heard of anyone doing it.

But honestly if you only drive 10-40 miles per day as you said, you will be fine with just Level 1.

So it seems. It didn’t at first but I discovered that a previous owner had set it to charge only between midnight and 6am. After I turned that off it was much better.

That's not the case. There was one or two people here on the forum who have residential CHAdeMO units. IIRC, there are 20kW units you can get for about $5000.

But are you said, the OP definitely doesn't need one.
