Garmin sports GPS devices, such as the Edge cyclecomputers, and Forerunner GPS watches for runners and triathletes, all accept input from a Garmin heart rate monitor strap. These straps work well, but their batteries last about three years or less if used regularly. After you remove the old/dead battery per instruction steps below, be sure to wait a full 60 seconds before inserting the new battery. This gives the unit time to reset. Otherwise, it may not recognize the new battery and won't give a reading to your device.
Difficulty: Easy
Time Required: 5 minutes
Here's How:
- Locate the battery compartment on the back of the heart rate strap transmitter unit (see photo).
- Use a coin (a quarter works best) to turn the battery cover counterclockwise (direction marked "open" on the cover).
- Remove the old battery.
- Wait a full 60 seconds to give the unit time to reset.
- Place the new battery in the compartment with the positive (+) side facing up.
- Make sure the rubber O-ring gasket is not damaged and is seated correctly.
- Align the threads, and use the quarter to twist the cover clockwise firmly, to close.
What You Need
- Replacement battery (CR2032: 3 volt).
- Coin for opening battery compartment (a quarter works best).
