After talking to Ken today, I figured I would get off my ass, and finally get around to replacing the battery for my heart rate monitor. For some reason, I thought it used a different connector for the battery, and this was the main reason I had procrastinated replacing the battery for so long. Obviously, I must have had my head up my ass, though. It ended up taking all of 5 minutes to take apart, and after a quick trip to Target and $4.00 later, I had my replacement battery. Here’s a photo of it running now.

I still gotta admire the laziness. Just the thought of a little extra effort on a mundane task kept you from doing it. I am truly envious and in awe of your powers of sloth.

Even more impressive is how long I procrastinated, must have been for 6 months or so.

I need to change my battery in my Polar Pacer, and could use some advice. Once I get the cover off, there is a gold cover, how do I take it off without damaging the unit?
Brian Pepple said
If I remember correctly, there’s some small clips holding it in place, though my memory could be fuzzy since it was a few years back when I did this.

I’m wondering how to change my battery in my Polar Pacer, I have the cover off, I don’t want to damage it. How do you get the gold cover off to get to the actual battery?

I just made a replacement chest strap for my Pacer, then discovered the battery was also dead. Pics were a great help. I’m off to get the battery next. Speaking of sloth, I’m leaving the open parts on my desk so I don’t get distracted before it’s complete. Thanks! -jh

I have a polar pacer hrm and recently had the battery replaced in the watch. Now
it appears that i also need to change the battery in the transmitter. Do you pry the

I am happy I found your website on orkut. Thank you for the sensible critique. Me and my husband were just preparing to do some research about this. I am very happy to see such good info being shared freely out there.
Best Regards,

To remove the gold plate after the back is removed requires only a slight clockwise twist. Don’t try to pry it off lest you break the contacts.

I have an old Polar Pacer and the battery is dead. Can I use any Polar chest strap for the Polar Pacer to work? Just want to know before I replace the battery. Thanks in advance
