On a 2012 iMac, Bluetooth issues are fairly common as the hardware is aging and macOS updates sometimes don’t play nicely with older Bluetooth chips. Since you’ve already ruled out the batteries, the next step is to figure out whether the problem is with the mouse itself, or with the iMac’s Bluetooth system.
I suggest starting by doing a quick reset of your Mac's Bluetooth module. To do so:
If the mouse still won’t connect, try pairing it with another Mac, iPad, or even a Windows PC that supports Bluetooth. If it works elsewhere, the iMac’s Bluetooth is likely the issue.
Finally, sometimes interference from Wi-Fi (especially on 2.4 GHz) can mess with Bluetooth, so try turning off Wi-Fi temporarily and see if the mouse shows up.

I'm not sure what happened but it's working again now! Thank you!
