So I have a Polar FT4 and I just replaced both batteries after a year because I noticed my heart rate was all over the place and now when I do the exact same workout some days my calories burned are way higher. This is even after I wash it. So is everyone's like that or do I need a new one?

    when you changed the batteries, did you somehow reset your personal settings like hight, weight etc ? I would double check that before investing in a new one.
