How long should my UPS last before dead battery?
I currently have an APC UPS as a backup for my VOIP home phone. The UPS's battery is a 7Ah 12volt. I have running off it a typical cable model (not sure of the watt draw), a typical wireless router (which draws about 5 watts), and a PAP2T phone adapter (which also draws about 5 watts).
Anyone have any idea how to figure out the run time off the UPS (perhaps assuming not a total battery drain so it doesn't kill the battery)?
