bought yesterday. Neither will work on batteries. The batteries are brand new and ive tested them with a battery tester and the battery tester is brand new. The batteries are duracell they say 9v2 on the package. The radios say they take one 9v battery. I dont know whats wrong.

The clock should still work on batteries, or maybe the batteries only act as a backup, so that when AC power is restored your clock is still set. Your cd player however will not work simply on a 9v battery.
