A hydroelectric dam can be classed as a battery as it stores energy. So if you removed the device from humidity and it holds charge it’s a battery.

it’s been spoken of before if you open up a Tesla battery it’s just little cells connected for the desired output.
the conductors are gradually increased in CSA to safely manage powere flow to prevent fire.

charging a balloon with your hair still hold the charge until it’s equilised.

Of course there will be limits to the generating capacity but scaling up will always produce more power using correct conductor size and safety precautions.

static electricity is physicaly of the same stuff as coal electricity.
