GREEN FUSION for Galaxy Watch Active 2 (44mm) Replacement Battery, EB-BR820ABY Battery Compatible with Samsung Galaxy Active 2 (44mm) SM-R820 SM-R825, with Installation Instruction & Repair Toolkit

This kit has more than what I really needed. The tools came in handy combined with another. I found the blue tool to be a bit thin on the end and almost like it would break when using to pull things apart so I swapped to another tool. The battery was functional and worked great after being replaced.

Replaced battery in accordance with instructions that came with the device and then attempted to turn on the device but it wouldn't turn on. Attempted to charge the watch and my charger indicated it wasn't charging. Took it apart a second time and redid everything and made sure the ribbon cables were making good contact with the main board and put it all back together. Same issue. Returning it isn't worth the time taking it apart a third time. Guessing the battery is dead on arrival.

Came with great step by step instructions and all the right tools. Install was a breeze and now my watch works again.

I'm giving 2 stars for trying. There are a couple things you should know before trying this repair. I was getting a blinking red light on the charger. This could mean that the battery is bad -or- a number of other things. The watch wouldn't reboot or do anything. So, I decided to replace the battery. I received the package in a timely manner. It contained several tools of questionable quality. I started by trying to remove the screws. A couple of the screws came out ok. One screw wouldn't budge. I noticed that the removed screws had what looked like to be blue locktite on the threads. This is what was making the screws difficult to remove. I tried heating the screwdriver to loosen the locktite. No good. I tried to pry open the case base to maybe loosen the grip on the last screw. I finally got the case back loose with the exception of the last screw. I tried numerous methods to loosen the screw. Finally, I used a small hammer and banged on the end of the screwdriver while inserted in the screw. This worked and I got the screw loose.The enclosed step by step brochure was helpful. Along with that and watching a you tube video, I was able to replace the battery. I was so happy with my accomplishment.However, when I went to start the watch, nothing. Same problem as before.The tolls in the kit are of poor quality. The razor blade broke, the plastic spludger was marred. I don't know what the other tools were for since the instructions didn't reference them and I couldn't find a use for them.YouBreakIFix will give me free estimate on what repairs are necessary. The estimate may be too high, but at least I'll know what the problem is.I don't know if the battery is any good since the watch won't start...This is more complicated than putting a new watch battery in a quartz watch. Good luck!

GREAT KIT!! Great battery kit comes with everything you need except for the 1.5mm screwdriver needs upgrades...Be sure to take your time and watch some How -to videos on the process.But my watch is brand new again!

I don't normally write reviews, but I'm compelled to do so in this case. I'm just so dang happy that this thing worked! I feel like my old watch has a new lease on life, and it was way easier than I thought. Took me about 20 minutes. The only complaint I have and thus the four stars is because I don't feel like they included the correct TriPoint screwdriver. Included is a Y000, but when I test fit it into one of the screws, it felt loose. Thankfully prior to purchase I had read some of the other reviews on here indicating that they strip the screws using the included screwdriver. So, I went to the local computer store that cells DIY tools, opened up a tool kit, and I was able to determine that the screw is actually probably closer to a Y0. So I purchased the kit for $12, and got cracking when I got home. Turns out the Y0 is a perfect fit. The repair was also a lot easier than I thought. I have tried to repair other modern-day electronics like a DJI drone, and I swear I would never attempt again because that one was really difficult. This one was super easy. The instructions that the vendor includes are also very good. Check out my pictures for detail on the difference in the screwdriver tips. Also in my pictures I show the tools I actually used. The vendor also includes an exacto knife and razor blade that I did not need. By the way another thing I try to indicate in my pictures is that the battery that I replaced was definitely bad. It had signs of becoming puffy. Hopefully that comes out in the pictures.

The tri-wing screwdriver that comes with the kit to loosen the four screws will damage your watch do not use that it'll strip the screws for about $4 you can buy a higher quality try Wing screwdriver the other tools in the kit are useful as far as the instructions I never read them this took me about 20 minutes and the battery lasts 55 hours

No se como deba calificar ya que supuse que era la batería la que estaba mal pero al cambiar la batería funcionaria. Así que no puedo decir que este mal el producto a menos que no esté funcionando la bateria
