Battery is dead on my Polar heart rate monitor (not the chest strap). The back comes off but it looks like there is a "knack" to getting the battery out.
Here are instructions (with images included) on how to replace the battery for a Polar F11: http://timlaqua.com/2008/09/how-to-replace-the-battery-in-a-polar-f11-heart-rate-monitor-hrm/
I've came across many Polar watches and there are two different types how rhe battery is held in place.
1) Battery contact is screwed down to movement plate with one ore two tiny screws. In this case you have to unscrew them and the contact will come off releasing the battery.
2) The battery contact is fitted using 'clip-on' assembly. In this case take a tweezers or metal pin and pull the contact end outwards. This will undo the contact and release the battery. You will find thet contact end if you will follow to that contact right into movement where it's clipped onto small plastic knob.
Details of the battery you will find written on the old one.
Do not forget to rate, please.
u may have started wearing a Polar F11 Fitness heart rate monitor to help you keep track of your pulse during cardiovascular exercise. The monitor consists of a strap with electrodes that you attach to your chest, which transmit heart rate data to a receiver worn on your wrist like a watch. The wrist unit stores data and settings that you can customize, such as your weight, height and target heart rates. However, you may wish to reset the unit and start over with new settings. You can reset your Polar F11 by following a few easy steps.
