Heh...where's it going to go?
Electrons like to move through...not sit.
But if they sit (battery)...they sit until they find a way forward...I doubt an unplugged charger is a pathway.

I charged two Wasabi batteries (brand new) for my Z fc in a Wasabi dual charger. I checked the voltage, and one showed 8.43, while the other was at 8.41v. That's out of a nominal 7.6v. I put the 8.41v back into the unplugged charger, and I'll check the voltage on each one every day.
Boy, is this exciting!

Hmm, I’m thinking one sample set isn’t a statistically valid test?

It's 100% valid for me and these batteries.

Jerry, you really need to get out more.
My answer would be "yes" but that is purely anecdotal as I have nothing to prove or disprove. Just a few instances where I accidently left a battery on a charger and found out later it was discharged. But it could be that it needed a charge before I connected it & forgot to plug in the charger.....
Jerry, you are indeed one busy man and have the curiosity of a cat!!! LOL
A slow day in Jerry’s life.

Jerry: You have way to much time on your hands. You could count the number of sesame seeds on a hamburger bun.
You could count the number of vertebra a giraffe has as compared to a human. ( The answer is a surprising number). You could create a whole new religion photographers will follow. How about creating a new language for butterflies to understand.
More importantly, batteries will lose charge overtime. I will have to ask my engineer son. Most likely, the answer is probably way way over my head. In all, I’m just kidding. Because when I keep alkaline batteries in the fridge, I’m good for a while. If I do that with my camera batteries, I will leave them in the fridge and never take them out.
Battery chargers have diodes, which are one way valves for electricity. Electrons can go one way but not the other.
Batteries are direct current (DC) and direct current can be stored whereas alternating current (AC like in your house) cannot be stored.
Diodes are used to convert AC into DC and therefore the electrons in the batteries cannot leak out.
Batteries fail when the insulating material inside them breaks down which is akin to a water bucket with holes in it. The more the material breaks down the faster the battery goes dead.
If you’re charging two batteries in the same charger and one is good and one bad the bad one can drain the good one. Even good batteries very slowly discharge but if the battery won’t charge, only charges partially or charges and loses that charge over a few days, the battery needs to be replaced.
Simplified electricity 101.

"It depends."
I use Depends, but I don't know how this involves batteries

I think what's Jerry is doing is really worth while. I would like to know if the unplug charger discharge the batery or that Wasabi (a highly recommended third party brand) isn't as good as genuine Nikon.

Yes, I try to keep busy. I try to find "important" things to do instead of housework. Checking the voltage in batteries is now one of the important things.
You know you’ve gotten old when your life revolves around checking battery voltages and living in fear daily of needing Depends. And last night my 3 year old grandson blacked my eye with his elbow. It’s embarrassing when a 3 year old kicks your butt.

No Depends for me - yet. It sounds like your reflexes are shot if a three-year-old can give you a black eye.
