I would also take a look and see if you can take the thing apart and if you can, go to a RC hobby store and buy some good nicad batteries and replace the battery pack that they come with. That's what I did when I got tired of the replacement pack that most cordless phones use and paying a lot for a battery pack that last a year and only an hour.. the one I built now lasts about 6 hours and cost about 10.00...

my 2 cents.
