That is NOT the case here! This is an excellent bit of kit. Battery was installed in the Gear S3 watch in November 2019. It is now mid-June 2020, and it is still going strong. Even after eight months, I still see 75-80% battery life left after a full day of use (including an hour every night of S-Health use). The stock battery it replaced, which was several years old and puffy, wouldn't even make it 8 hours before it was dead. Changing the battery is not very difficult, although it is a bit fiddly and will cause you to ponder how they are able to mass produce these watches. The tools it comes with are surprisingly good quality: the screwdrivers have well machined aluminum handles, and it includes a good spudger that has come in handy several times on other projects. The instructions are quite good, with just a few areas that are just a touch confusing (but easy to figure out once you're in there), and clear warnings on areas to be careful. If your watch battery is not holding a charge anymore, I highly recommend this kit. The quality is excellent for the price, and the battery has held up very well. Review: Great replacement battery kit. - Replacement battery working great 4 months in. Really not difficult, just follow the directions. Hardest part was prying the back off the watch. I wish I had known about these kits before I replaced the last watch for not holding a charge. ## Features - Battery life not what it used to be?

That is NOT the case here! This is an excellent bit of kit. Battery was installed in the Gear S3 watch in November 2019. It is now mid-June 2020, and it is still going strong.

Really not difficult, just follow the directions. Hardest part was prying the back off the watch. I wish I had known about these kits before I replaced the last watch for not holding a charge. ### ⭐⭐⭐⭐ Given a new life to my watch *by K***P on September 24, 2021* I was irritated with unexpected shutdown of my Galaxy watch. Turned out to be battery issue and this replacement given a new lease of life to my watch. Now the watch go on for almost 2.5 days without power saving mode on moderate use which is same as when I got the watch band new. The battery seems identical to what was in watch originally. supplied Y screwdriver seems of very good quality but + screwdriver seems to be a piece of junk (use your own). The process of replacement needs lot of patience and some level of experience in dealing with small electronics. If you are not technically inclined, don't try this. Note: Water seal may get damaged in this process so if you want your watch to be waterproof again, have some E6000 glue handy and put a thin line over the seal before closing the back cover. I have done that and mine seems waterproof again. ## Frequently Bought Together - oGoDeal Replacement Battery for Samsung Gear S3 Frontier(SM-R760) and Gear S3 Classic 3.85V 380mAh Battery SM-R770,BR760,R765 EB-BR760ABE GH43-04699A Battery with DIY Repair Tools - Emilydeals for Gear S3 Charger, Replacement Charging Cradle Dock for Samsung Gear S3 Classic/Frontier Smart Watch (Black) - V-MORO Compatible with Samsung Gear S3 Frontier Bands/Galaxy Watch 3 45mm/Galaxy Watch 46mm(2019),22mm Solid Stainless Steel Metal Business Bracelet Strap Black(Not for galaxy watch 4 classic 46mm) --- ## Why Shop on Desertcart? - πŸ›’ **Trusted by 1.3+ Million Shoppers** β€” Serving international shoppers since 2016 - 🌍 **Shop Globally** β€” Access 737+ million products across 21 categories - πŸ’° **No Hidden Fees** β€” All customs, duties, and taxes included in the price - πŸ”„ **15-Day Free Returns** β€” Hassle-free returns (30 days for PRO members) - πŸ”’ **Secure Payments** β€” Trusted payment options with buyer protection - ⭐ **TrustPilot Rated 4.5/5** β€” Based on 8,000+ happy customer reviews **Shop now:** [https://www.desertcart.jp/products/136188625-ogodeal-380mah-battery-for-samsung-gear-s3-frontier-classic-compatible](https://www.desertcart.jp/products/136188625-ogodeal-380mah-battery-for-samsung-gear-s3-frontier-classic-compatible) --- *Product available on Desertcart Japan* *Store origin: JP* *Last updated: 2026-07-13*
