Button batteries suck and are absolutely e-waste, I have a small recycled sealable container just to collect dead CR2032’s. Every time I go through another one, I add another mental tally to eventually just mod any device I have that takes CR2032’s to instead take rechargeable AA’s. I’ve always suspected that the batteries are just too small to store enough energy to make the size worth it, and that devices that take them drain them on idle when the batteries are left in. I’ve had many CR2032 powered devices where they worked fine, I put them in a drawer, pull them out some weeks or months later, and it’s already dead. Battery drains without using whatever it’s in. Bad design from all directions
