If you leave a battery in a charger that isn't plugged in, will the charger drain the battery? This topic was discussed in 2019, and the conclusion was: It depends. Time for a test.
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!
I'm on the edge of my seat!

I think I wet myself in so excited! LOL
It would depend on the design of the charging circuitry, whether the circuitry is a load on the battery and how much.
eg. Reverse leakage on a diode is only micro-amps.

Jerry, you have waaayyyy too much time on your hands. Please come down here & help my husband clean out & organize our shed and garage.
Sounds like most here have no idea…

Sounds like you have a real good grasp on most forums.

Is that your final answer?

Nah, my initial answer was my final answer.

Bet you get a charge out of it!
Now if you REALLY want your audience waiting with bated breath, test the voltage with a load. The way you tell a good battery from a bad one is to put a load on it. A good one will have lower voltage, but the voltage on a bad one drops considerably.
Think of your spare tire in your car. You pull it out of the trunk and it appears to be fully inflated. Put it on, lower the jack and with the load on it, it’s half flat.
Same thing with electricity. Electrical voltage is electrical pressure.
Good evening Jerry, from my experience with rechargeable batteries in the power tool field it does not matter what device you leave them in, they will generally loose 1 to 2 percent of their charge over a 24 to 48 hour period. The amount of charge they will loose depends on the ambient temperature of the place where they are being stored. Warmer places increases the voltage loss while cooler places reduces the loss. I'd be interested to see what results your experiment produces.

Jerry' like others have said it's a crapshoot some chargers will discharge the batteries if left in a charger that IS NOT plugged in, I have had this happen numerous times a large battery chargers with a timer that shut off and the night shift left running. A real bad idea.
