Polar Heart Rate Monitor - battery question

maurierose

Hiyas all,

I have a Polar F11 - it won't upload data to the polar site (seems quieter? not sure though), but seems to be fine otherwise..... so my question is - when do you know it's time to change the battery? Are there signs ahead of time, or does it just go completely dead?

Has anyone just gone to a jeweler to change it (or walmart?) or did you bite the bullet and just mail it in? I sooooo don't want to be without it for a few weeks, much less a few days. I am an HRM addict, and a MFP addict, heaven save me... :bigsmile:

Thanks in advance!

I hope someone can answer this because I was wondering the same thing. Mine keeps jumping to higher heart rates when I know for a fact it shouldn't have been that high.

my dh has a polar f6 and went to a jeweler to have the battery changed. it was cheap and quick, but they said they can no longer guarantee that it's waterproof.

Thanks Beth!! That may be my deciding factor then, as I use mine during the summer while swimming..... great to know!!
