Polar HRM Battery Change
I’ve changed my Polar battery multiple times. The price Polar charges for a battery change is a complete rip off. It’s such a scam. Almost as bad as paying so much for razor blades.
- Thoroughly clean your watch before taking it apart.
- Remove the screws (small, easy to lose)
- Separate the two halves and carefully remove the gasket from its channel
- The battery should now be visible. Mine is model CR2354 and can be purchased for under $10.
NOTE: This is an electronic device so be very careful not to discharge any static while touching the interior.
- While you have the case apart clean out any dust or grit that has collected near and in the channel that the gasket fits within.
- Clean the gasket with a little bit of water and dish soap. Allow time to dry.
- Replace the battery (you should see the watch display reset)
- When the gasket is dry, place it back into the channel on one half of the body.
- Place the two halves back together. Take care that the gasket seats correctly and you don’t pinch it.
- Insert the screws and begin tightening in a balanced rotation, similar to how you would tighten lugnuts. If you tighten only one at a time you may create a pinch point which can cause a leak. Also, don’t over tighten. How tight you ask? Sorry, I do it by feel. Just realize you aren’t trying to lock down a disc rotor.
You should now have a happy full of juice Polar.
Now go ride!
