Subject: RE: Polar HRM battery replacementI change mine myself. 4 small screws hold the back on and though the battery is sometimes hard to find, Radio Shack always has it. I have changed it three times and have had the monitor for about 7 years or so. HOWEVER, mine does now leak and one of the buttons has stopped working. I think this is more a function of age and use, but it could be because I opened the back myself. Though that wouldn't have caused the button to fail. It still works, you just have to push it REAL hard to get it to work. I have also changed other people's batteries and haven't heard any complaints. Come to think of it, I haven't even heard from them at all! Oh Oh!mmmm... ![](https://beginnertriathlete.com/discussion/images/emoticons/smile.gif) |
