Rated 1 out of 5 by from Epic fail Wanted to replace the missing battery cover for my wife's FT40. Turns out that the battery cover is for other Polar products, but they advertised for the FT40 because the battery fits. Anyway, I wanted a replacement battery cover, not a battery that can be purchased at any drugstore or grocery store. Disappointed.

Rated 4 out of 5 by from Replacement Batteries--F7 I needed replacement batteries for my F7 and sensor. The website is not particularly user friendly but I eventually found what I needed. That's why my review is only "good". The batteries were shipped and received promptly. Replacement of the batteries was easily accomplished. I'm now good to go.

Rated 2 out of 5 by from Ok I think the HRM strap is bad because after I changed the battery it still didn't work.

Rated 3 out of 5 by from I wish I had known it was this easy I bought a replacement battery on my own and it lasted 2 seconds. This one works fine although the gasket is too loose so it is not waterproof.

Rated 2 out of 5 by from I had to quit using it. I used one of these up to about a year ago. It worked well except for the following problem. Every time I changed the battery, a little bit of the groove on the soft plastic battery cover cap got gouged out so that eventually I simply could not change the battery. The batteries are not cheap and having to send it back for service every few months is even less cheap. So I tossed it.
