unbearable noise in the background because of the battery

Summary: I was very excited when I got my zx1. however after charging the battery and try it for the first time, i was bummed. there's an annoying noise of continous humming or whistling in the background. The sound is loud enough to be heard by the ear. Definitely not a fault that a video cam should have. Funny thing is, when I try using the zx1 with other battery (in my case i tried my old camera worn out battery) the sound is not too loud anymore.
