How long do you think a regular 9volt battery would last powering this clock? I’d like to hide the battery for a project, and don’t really want to use 6 D or C cells…. or maybe use 6 D cells and a 9v battery in parallel to keep the 9v battery powering the clock if the D cells are removed….. but for how long will a 9volt battery power the clock?
this will be for a boy scout Military Spy type event 🙂
