Hello, all. I've got an ~8 year old GE brand answering machine (like this one:that has worked flawlessly until about a month ago when the machine announced "Low battery". As usual I replaced the 9v batt with a fresh one and the announcement was gone. The next day I got the message again. Took out the battery and checked with a VOM (yea I know it wasn't under load) and the terminal voltage was only about 6 volts. Put in another fresh battery and got the same results after a day. Prior to all this the battery would last for at least a year without needing to be replaced. In all other respects the device works fine but with a nearly exhausted (or no battery) the box resets to defaults if the power from the wall wart adapter is interrupted.
Any ideas what could be pulling the battery prematurely low? Thanks for your time and comment. Sincerely,
