It's recommended that battery replacement for Polar watches be handled by those qualified to do the job. But if you want to save money and time, you can replace the battery yourself. However, replacing the Polar watch battery yourself can invalidate the warranty on your watch. This is why Polar strongly recommends that you send the watch to them for battery replacement.

  1. 1

    Remove the back of the watch to expose the battery. If you are unable to easily remove the watch backing, wedge a knife in the space between the body of the watch and the back of the watch. Use the jeweller's screwdriver to remove the four small screws.

  2. 2

    Notice the numbers on the battery. The battery number is necessary to buy a new battery. Do not remove the old battery until you have a new one.

  3. 3

    Insert a paper clip in the semicircular opening that is adjacent to the battery; inside there is a latch that releases the metal battery cover. Release the latch to remove the metal cover.

  4. 4

    Match the old battery to the one at any electronics or jewellery store. The store will be able to help you locate the same battery for your watch. Polar watches have several model numbers and use a different battery for each model number.

  5. 5

    Gently press the new battery into the watch, until you hear a click. Make sure the battery numbers are facing up. Replace the four small screws and replace the back of the watch.
