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.

Rated 5 out of 5 by from Self replacement of batteries fantastic feature! I bought this replacement battery for my FT60. SO EASY to replace old battery now and no need to send HR monitor back to Polar. All components included. VERY happy with purchase and so fast to arrive!

Rated 5 out of 5 by from Terrific Product It's a better with the lid. I destroyed the existing cap on my heart rate monitor, so I ordered this replacement. The battery and lid work. It was shipped and delivered, so yeah awesome experience!

Rated 3 out of 5 by from battery replacment The only think I like to add is if I can find a good tool to open and close the cover! Maybe you guys can start working on a rechargeable battery.

Rated 3 out of 5 by from Gaskets too big The cap was fine, battery was fine but the gasket was too big. I got 2 kits and in one, the gasket was too big to screw the cap on without the gasket popping out and in the second kit (bought 2 to have a spare) the gasket was bigger than the biggest part of the lid so there was no way to put it on. I wrote to customer service and new gaskets are getting shipped to me. Nice customer service! I hope these are the right size. The unit will not be waterproof until I get the right size gasket.
