162mAh SP282024 Battery Replacement Compatible with Fitbit Sense 2 Fitness Smartwatch FB521

Worked on my fitbit sense 2!!! My original watch battery was draining quick, most times within a couple of hours. It all started when fitbit said there is an update for my sense 2 and the update would never finish because the battery was draining. Suspecting it was a battery problem, I took a chance with this item rather than buying a new watch. The hardest part was prying off the screen. You need to get the 1mm pry tool, which I did not have originally and I cracked the screen. I ordered a replacement screen separately, which worked too! Anyway, the second hardest part was ensuring this battery was properly seated on to the connector. I used my finger feel because the ribbon connector is too small to confirm it was seated using just the plastic tools. Watch the whole process on youtube. I recommend having a lighted magnifying glass because parts are very small. I've had the watch working for a few weeks now and it takes several days to drain the battery just like when it was new.

Tools are worthless but the battery works good.

Returned. Unable to change battery.

Tools and battery look great I have not tried installing yet

Not the exact size of battery for the watch

I have no idea if the battery works but the tools are low quality plastic that beak easily and there are no instructions. Following the instructions I could find online resulted in breaking the watch rather than replacing the battery.
