Yesterday I opened up an old electric toothbrush, had one normal battery (AA) and one rechargable battery. Only the normal one had this kind of mold fungus on it.

Putting your Alkaline batteries in a fridge to keep them cold supposedly keeps them from leaking and somehow makes them last longer/keep their charge. Not sure if it’s true but my Grandpa swears on it.
It’s not mold it’s the liquid from the battery coming out of it. If you see such a battery, throw it immediately away! It is poisonous and can cause serious chemical reactions
The corrosive liquid inside the battery. Non-rechargeable batteries contain acids or bases that eat away the material of the battery to produce electricity. If you let a discharged battery linger too long the fluid starts eating through the casing and leaks. After that it dries into a crusty mess of dry acid salts and rust.
You can clean up the mess left in your equipment with distilled vinegar. Is reacts with it and makes it easy to remove.
