44mm Active 2 Battery Replacement for Samsung Galaxy Watch EB-BR820ABY, Compatible with Galaxy Active 2 SM-R820 with Repair Tools + Installation Instruction

Update: After 5 days of low charge the battery is like new. Watch lasts almost 2 days. Great buy.Replacement was fairly easy with the instructions and video. I'm on my third drain and charge. Put on my watch lay night at 100%, put in sleep mode, woke up and it's at 22%. Original battery would only drop 10-20% overnight in sleep mode. Not sure if the replacement battery is faulty or it still needs to have me full charge to nearly drained cycles. So far not impressed.

Battery replacement is pretty straight forward, took about 30 minutes. There are a few "how to" videos on YouTube that makes the process much easier.The suppiled tools are just okay. The phillps screw driver didn't do the job so I used a better quality one I had from a few phone repairs. The razor blade was useful for opening the back by using it long ways along the groove to separate the back shell. Battery longevity has not been tested yet as I just installed it.

The battery did not work, I called Samsung and was told that the battery needed to be replaced, I ordered this battery and the watch did not turn on, it flashed a green screen just like with the original dead battery.

This kit worked exactly as indicated. I was able to follow a YouTube video to give my Galaxy Watch 3 a new life. The spudger tool that came with the kit was broken, but they quickly sent out a replacement kit.

Make sure you follow directions on charging. It makes a difference.

It worked great and lasted over a day on a full charge. Then after a week, it would no longer hold any charge at all.

This battery replacement kit came with instructions. Easy to follow. Replaced the batteries about three weeks ago now and everything works perfectly.

Very detailed, everything that you need to replace the battery of your Samsung smartwatch.
