MPF 300mAh 361-00034-02, FLPB342735-P1 Battery for Garmin Fenix 3 and Fenix 3 HR Fitness GPS Smartwatch

Battery doesn't last long. Doesn't perform as well as the original battery which is 10years old.

I have my Fenix 3 watch for three years now. Original battery lasted almost a week in the beginning and degraded to about day and a half now so i decided to replace it. The replacement process is straight forward and tools provided with the set work perfectly. However, the battery itself last only about 1.5 - 2 days - which is way shorter than original battery performance at the beginning of use

Ordered this product. Replaced my Fenix 3HR battery. Very diligent in the replacement and took care to make sure the battery connector was seated properly on the motherboard. Battery was completely dead. I thought I had bricked my watch.Put original battery back in and the watch was back to normal.Product doesn't work.

It worked fine and I found instructions on line but, after I got it back together I had to take it back apart because it was rattling around inside the watch. I added a small piece of double sided tape adding a piece to the kit would have been very helpful.

Was able to replace the battery in my Qualix 3Battery fit and the tools supplied was exactly what was needed for the repair

Despite all the other bad reviews, I thought by chance I might get a good one. That didn't happen. At first it was equal to my 5 year old battery, but after about a month of use a 100% charge only last about 5 hours. Would not recommend.

Everything was as description. Battery was the same as my old battery.

It took a few weeks for charging to stabilize. Worked well for a few weeks then suddenly stopped taking a charge at all. Very disappointing. Direction from product support was to try reinstalling the battery, or using a different charger.
