I used the CR2032 instead!

        Comments about Panasonic Dantona® CR2050 3V/290mAh Lithium High-Energy Coin Cell:

        I have an ACUMEN sports heart-rate monitor that needed the batteries of both the watch and chest-monitor replaced. Without reading the user manual, I assumed that the CR2050 battery I removed from the chest monitor, because of its unusual tiered profile, was unique and no other battery would do. I soon realized that the CR2050 was not available in Australia and until I accessed RadioShack's Web site and read the review by "Frustrated" from San Antonio, I thought my Acumen monitor was a dinosaur and needed burial. "Frustrated's" review lead me to read the Acumen user-manual and my problem was fixed in a flash with the use of the readily available CR2032 for both watch and chest monitor. Acumen recommends the CR2050 because it lasts a year longer in the chest monitor (2.5yrs instead of 1.5 yrs).
        Many thanks to "Frustrated" for sharing his/her experience and to RadioShack for their interactive Web site - yes, we are never too old to be reminded to read the user-manual first!

          I looked for this battery at several local stores and on the internet. You were the only company who carried it. I us it almost every day in my heart rate monitor. It's great knowing exactly how great of a work out you get right away and you also know that your not going over your limits. Thanks.

          Bad Battery

          By Frustrated

          from San Antonio, TX

          Comments about Panasonic Dantona® CR2050 3V/290mAh Lithium High-Energy Coin Cell:

          [...] It was for my exercise heart monitor. I have two and tried in either one thinking something must no longer work. After reading again I could use either the 2050 (in the original)which needed to be special ordered or the 2032 that is also in the watch component. So I went to my grocery store and bought it and guess what it works in both monitors. So I'm out of the cost of the battery and the shipping. And a lot of time.
