It turned out the new battery didn't work and I tried to get the display off again, but it stuck better than the original. I never got the display off and ended up buying a new apple watch... **Q: This battery is getting hot when I put it to charge , this is now normal need help with item** A: I replaced the battery and it got hot when I charged and the moment I took the watch off the charger, the watch turned off. I had but two choices: 1) Open my watch again, take the battery out, send it back and order a replacement, or 2) just let it slip.... I decided for 2), Having had my 1st generation watch for 5 years, I felt that could be justified. My assumption is: The replacement batteries for 1st generation watches have been sitting on shelves for 5 years as well, and the chance to get a dud is not small.... **Q: I need a kit. When can I expect the stock?** A: Now it has stock please check it **Q: Does the adhesive make it water proof again?** A: It was never "water proof" from the start. It seals the face to the housing making it somewhat water-resistant, but I would not recommend getting wet no matter what. ## Customer Reviews ### ⭐⭐⭐⭐⭐ It Worked *by B***B on June 24, 2021* Old Iwatch battery was swollen and dead. I partially removed the face and installed the new battery per Youtube instructions. The hard part is installing the new gasket. It’s brown side down on the watch body, but on my 42 mm watch, there are two little bumps on the body which must line up with the indentations on the gasket. The gasket itself is a thin, sticky membrane. The watch face sealed well. The battery works well, but I first got the green snake of death, which went away after 20 minutes. It fully charged in about 4 hours and the watch fully functions. ### ⭐⭐⭐⭐⭐ Keeping my old watch at a good price *by M***K on September 12, 2020* The first battery was dead on arrival at 14% and it would not recharge. I sent an email to the seller and received another kit in two days.That one worked great. Even though it was easy to install, with the practice of the first one I made no mistakes on the second install ### ⭐ Badly Outdated Battery! - New Old Stock (NOS) from Original Apple Production in 2015? *by R***R on March 6, 2021* This battery very plausibly comes from the very same factory that manufactured the parts Apple used to build original 2015 Apple Watches, since the replacement battery I received has markings indicating that it was made way back in July 2015!Rechargeable Lithium-Ion batteries are known to have a limited shelf life of between 2-4 years, so by even attempting to use this badly outdated part to attempt repair of your Apple Watch battery you are basically demonstrating the triumph of optimism over reason. Many other Amazon reviews of this product mention receiving batteries that were either totally DOA or had very poor performance after installation, as should be expected after installing a replacement part as old or older than the battery that originally came in the watch.I'm sending this kit back unused for a refund and will locate a newer & fresher part from some other source. --- ## 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.co.uk/products/148295302-original-battery-cell-for-apple-watch-series-1-battery-replacement](https://www.desertcart.co.uk/products/148295302-original-battery-cell-for-apple-watch-series-1-battery-replacement) --- *Product available on Desertcart United Kingdom* *Store origin: GB* *Last updated: 2026-06-19*
