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.

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
