I have often left an extra battery in a charger (unplugged) after charging, and have never noticed any drain on the battery. The battery has always shown a full charge when installed in the camera.

If you leave a camera battery in its charger after unplugging it from AC power, is there drain on the battery? Will a battery run down in storage in the charger, more than if it is out of the charger?

If I may suggest,what happens after you plug it back in? If there is any significant drainage, it will take time to recharge, no?

On general principle, knowing there is an electronic circuit making contact with the battery terminals, I remove the battery. If the charger is plugged in that would add in the house hold circuits. While there are more than likely diodes in the circuit to prevent any reverse current flow, why take the chance?

Why? Some times in the past I have traveled with a battery in the charger, just to save space and to keep things together. But to be safe I turn the battery around backwards so there is no electrical contact between the battery and the charger.

Ditto that! Simple solution I do myself. But if they wanted to find out as a little experiment, leave it in contact for awhile and then just plug it back! If there is any significant drainage it will just take a significant time to recharge, I would think

I can't see why it would start to discharge. The battery has no preconceived idea of location.

A schematic of the charger is the only way to get the answer, anything else is a SWAG.

Would that give you a definitive answer regarding battery discharge?

There's a reason why batteries come with terminal covers. Any time a circuit, however intermittent or flawed is made across the terminals, a flow will occur. Even in your pocket.

No, the reason for terminal covers is to prevent short circuits from metal objects. That could result in fire or worse. Think about that before you put a battery in your pocket with change or keys. Batteries do not dicharge in an empty pocket.

It would be difficult to test that. The discharge would be very slight, if there is any at all. Sitting on a shelf or in a camera, a battery will discharge.

A sensitive ammeter will show the discharge.

Don't know if this helps, but I had this same question a few weeks ago. I charged up a battery on a Canon charger, unplugged the charger from the wall and left the battery in the charger for 24 hours. I then plugged it back in and it took about 20 seconds for the charger light to turn from yellow to green. So no really significant amount of energy was drained if any. However, this same test would have to be done over a much longer period to give a definitive answer.

I have found that when leaving a battery in the charger AND with the pair placed in my camera bag--- the battery runs down rather quickly. I don; t do that anymore. That is my Nikon charger(s) for D750 and D500.
