Battery for Samsung Gear S3 Frontier Battery 580mAh(SM-R760) 2026Upgrade High Capacity, Replacement Battery for SM-R770, BR760, R765 with Professional Repair Tool Kit

Battery died in my S3 several years ago, I had just kinda thrown it in a desk drawer and forgot about it. Ran across it a few weeks ago. TL;DR is I decided to grab a batter and see if it would fix it. Took like 20 mins to change the battery out, worked immediately. Battery was full on delivery. Finished installing the battery 3 days ago, and the charge level as of today is 25%. So I guess it works. Included tools are fine. I couldnt get the back door off w/ just the little plastic guitar pick thingy, so I just used a razor blade really carefully to get it started a little, then finished with the pick. Problem solved. Just take your time disconnecting & reconnecting the leads once you get it open, not a whole lot to it. Bought this one because it was the cheapest I found. Mixed reviews so I guess YMMV, but the one I got seems good to go.

The battery lasts much longer than the original that came in the watch. the battery came with instructions for install and fit perfectly into my galaxy 3 Frontier. really good value to keep a older watch running

I do work similar to this. So I thought this would be easy no it's not. But after I got it in the battery worked great for two days. But when I went to recharge it it wouldn't take a charge I'm going to try buying a new charger. About my charger used to work

I recently bought a gear s3 but it came with a bad battery which won't hold a charge so I needed a replacement. Bought this one because of the price. It was not that hard to Install. It's now been a month and its still working flawlessly and the battery is not expanded. It lasts about 2 days with always on display. Its a good battery.

Tools work. The battery terminal is in the wrong location. I didn't know that till I cracked the watch open. Do not buy.

The battery fit and worked perfectly and last a lot longer than the original. I should have dock this review one star because one of the screw drivers had a broken tip. I had one at home that fit, and this defect didn't really bother me. I am very happy with this purchase.

Brought some much needed life back to my Samsung galaxy gear s3 frontier. Instillation wasn't too hard if you've ever replaced electronic parts before. The hardest part was getting the back of the case off. The little spudger tool they provided was of no help. Something much sharper is needed. I ended up using a razor blade.

Kit de herramientas muy útil, Instrucciones claras lo que permite realizar el cambio con facilidad. Mi reloj tiene muchos meses con esta bateria y hasta la fecha funciona a la perfección.
