Replacement Battery for Galaxy Watch Active 2 (44mm), EB-BR820ABY Battery for Samsung Watch Active 2 SM-R820 SM-R825 44mm, with Repair Tools & Instruction

I replaced the battery exactly the way the directions showed me. It was easier to do than I thought it would be. BUT, my problem is not the battery. Must be something else causing the watch to not turn on and probably not worth the effort needed to make it work again!

Had a swollen battery on my Active 2 44mm that actually pushed out the digitizer and screen of my phone.The kit had everything I needed to replace battery along with instructions that looked like the ones from the IFixit site.Anyway, I followed the instructions which along with the fact that the active2 watch was well designed and had no trouble except for the 4 screws that held the back and were coated with thread-locking compound. After replacing the battery, I followed the instruction from IFixit and charged it up to 100% plus 1 hour. Then discharged it unit it stopped operating. This actually took longer than previous times, which made me aware how excellent this battery is. Then recharged it to 100%. The description for the item states that this needs to be done 3 times. (See the second bullet point about calibrating the battery management system.)I guess I was not aware how my original battery was decreasing it's capacity.My kit was actually better than the one shown since it contained two screw drivers, one orange one that is a very small phillips, and a black one that is 3 lobed for the screws on the back. Without the latter one, I don't think I would be able to have done the repair. The tweezers and the spudger were definitely useful. The battery adhesive a must.Be careful with battery disposal.
