How many battery-operated devices do you have in your home?

A student asked me this question today. They were looking into lithium batteries and e-waste and whatnot.

My initial response was something low, like maybe five or six, but the more I thought about it, the higher the number kept climbing — old phones, key fobs, wireless mice, flashlights, a food thermometer, etc.

I’m not sure I have an official count yet, but the number is WAY higher than my gut reaction. I also thought it was an interesting thought experiment, so I figured I’d ask here to prompt people to do their own inventory.

How many battery-operated devices do you have in your home? (They don’t have to specifically be lithium batteries, but if you want to limit it to just that, feel free).
