## Description

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

Review: Revived my fitbit sense 2, just like new! - 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.
Review: Good battery, bad tools - Tools are worthless but the battery works good.
