[580mAh]Battery for Samsung Gear S3 Frontier SM-R760, 2025 New Upgraded High Capacity Replacement Battery for Gear S3 Classic SM-R770 R770 BR760 R765 EB-BR760ABE, GH43-04699A with Repair Tool Kits

For the cost, this was a decent product. The tools were of low quality, I had to file tip of the three-pointed driver to get enough engagement to remove the casing screws on my watch. The battery itself fit and although the battery contact tab was little bit oversized making the fit a point of difficulty. Overall, I was successful and my watch seems to be maintaining a charge longer than when new.Update: Raised the Rating to 5-Stars - The seller reached out to me and offered me a Full Refund. I am declining the refund because the Battery functions just fine and I was able to complete the replacement utilizing the tools that came in the kit.

This is the second time I have replace the battery in my Samsung Frontier G3. The first replacement completed a couple years ago stopped charging. When I saw the larger 580mAh battery available, I chose to get the watch running again. Tools were fine, Battery was fine. Yes, it did take a bit to get the battery connector into the correct position but it was the correct size and fit. The weakest part of the G3 Samsung watch was battery life but this seems to have helped. A battery replacement at this price is a much better decision than a new $300+ watch. There is nothing to loose here.....

We purchased 2 watches. One worked for awhile but powered down and would not restart. The other one never held a charge and we replaced both chargers. The second one never powered back on. We purchased the warranty on them and that was useless. Do not buy these watches or the warranty offered. A real waste of time and money

I would definitely recommend this battery it totally changes the charging and battery life of the watch the fix it shops wanted almost $200 to repair but for about 15 minutes and and $14 I fixed it my self and now I have a little over 2 days charge.

The connector that connects the battery terminal to the battery cradle inside the Gear S3 Frontier is slightly smaller. The battery worked for a minute but ultimately fried the watch. (May have been how I put it together or the charger I used but now the watch doesn’t power on even with the old battery installed.)Your MMV but I would try and get a direct replacement from Samsung. This isn’t an easy fix to replace the battery so be warned it may not work after assembly

Works and fit perfectly!!

1) I was able to get the battery in and it's charging up now..2) the tri screw driver does fit supplied doesn't fit3) The battery connector doesn't fit. I was able to mash it in, but it's a fraction to big.4) This is just a FYI, but my watch had adhesive on the battery.5) I'll try to update with the new battery life.

I have had this battery for 7 months today it has started refusing to charge battery tested the day I got it at 210 Mah its no were near the 580mah they claimed the screw drivers were junk the battery barely fit even though it was smaller then oem battery. Today the charger started flashing red saying it won't charge and it won't charge with the watch off or On. Connector thst installed on board was a bit big but it clipped on fine for me. Don't belive the mah claims for any knock off battery. Wish it was better but 7 months wasn't bad for the price I paid just wished it lasted the 8 years my orginal battery did but all in all pretty happy with the price to purchase and quality ratio.
