Nice battery that fits perfectly.
Longevity is unknown, but so far it performs correctly.

Heart Rate Measurement Not Accurate At All
8 of 17 found this helpful I’ve tried about every brand of fitness trackers/watch there is. This is a great compromise between fitness and having a good looking watch. I really wanted this to be the end of my search for the perfect combination fitness tracker/watch and something that would compete with the Apple Watch. Unfortunately, as well designed and functional as it is, the heart rate tracking is so far off it is useless and pretty much negates using it as a serious fitness device. Often during rigorous exercise, the heart rate would show 80-90 bpm when it should have been in the 140 range. Then, when taking a slow walk, it would show a heart rate in the 130’s +. I had two of these and they both exhibited the same lack of accuracy in heart rate tracking. The Garmin eccosystem is nice and easy to understand, but if a fitness device can’t measure heart rate accurately, then what’s the use.

Terrible quality. 50% failure rate.
Terrible quality. 50% failure rate. Arrived dead. Replacement arrived dead. Had to be replaced twice. Out of 4 batteries, only one eventually worked. Manufacturer Vanon on the bottom. Steer clear.
