I borrowed an incubator from school that's fairly old and so they didn't know what kind of battery. Any suggestions please, I need to put eggs in ASAP. And I don't want to have to deal with getting a new thermometer since this one is designed specially for this incubator. I've already tried looking up the incubator and thermometer name but I might just suck at looking.. The incubator name is roll-x rx 2, and it's by Lyons.
