How long will the batter last in this “battery backup clock”?
Karl asked:
It says battery backup and has a spot for a 9 volt. Will it run on just battery with no electricity for very long?

Battery backup is used when the power goes out to your house/apartment. The length it lasts varies based on how new the battery is. Basic information like that can probably be found on the website for the battery. Daniel

The battery is to keep the digital clock running in the event of a power failure. It will not keep the display showing. I get a year out of my backup battery only because I change it at the same time I change the backups in my smoke detectors. Desert Dust
