Could you check the battery in the unit you bought and post the particulars (brand, size, voltage, part number)?
It uses a pair of AAA's, so you won't have a problem there. The unit comes with a little foam case. The case has cutouts for batteries, so you can store batteries outside of the unit for extended periods. Not like we live anyplace where you couldn't see the sky for weeks at a time... Michael P.S.
