I recently had someone ask me about the use of a ChipCorder with a 3 volt lithium button cell. I have seen many applications that used 1 or 2 of these cells in series to power the device. A ChipCorder will work just fine with a lithium button cell (or 2 in series) , if you want to use those batteries. You should note however that the chemistry of those cells dictates a recovery time. That is, as you playback messages continuously, you will see the battery's internal resistance go up and the output will get distorted. If you then wait a view minutes and then play a message, it will again sound OK.
That is, a lithium cell is good for interment duty when driving a ChipCorder and not continuous duty.
