What uses a 3V coin cell battery?

These come with my water filters to power the reminder light, which I never use. I been saving them in hopes of finding some gadget they'll fit. Can anyone suggest something useful? For instance: do any wireless mice use them?

Update:

It's a CR2032.

    Mostly small things, or things for backup power.

    It depends in the size of the cell what can use it too. Common is a CR3032.

    I have seen TV and VCR remotes that use the 2025. Some car alarm fobs also use them. I believe some diabetes (blood sugar) testers also use them.
