The Yong Heng pumps obviously (IMO) must have an internal battery not connected to the AC power source, that powers the temperature gauge located on the top of the unit. Where is this battery and how do you replace it?

Yes they do. It’s inside the case for the temp meter. I think CR 3032 size but don’t quote me on that. You can pry up the case and remove it from where it’s mounted, since it’s just kinda press fit in there. Look at the underside to make sure.
