Do I need to replace the battery?** A: A couple of years ago, mine stopped accepting a charge, but I didn't know whether the problem was the watch or the charger since I only had one of each. I happen to live 5 minutes from an Apple Store, so I brought both in and found out that the charger had gone bad. Replacing that fixed the problem. Now my watch charges fine, but often doesn't last the whole day before running low, which is why I'm looking at replacing the battery. **Q: Does this kit comes with the adhesive piece to paste the screen back to the Apple Watch?** A: Yes But the adhesive tape they came with is not very good and hard to apply. I used E8000 adhesive gel which works much better **Q: How long should it be connected to charger before the screen comes on?** A: Mine came on in less than 30 min. **Q: Does this kit come with adhesive to reattached watch face?** A: Yes it does but don’t buy it. This product flat-out will not work and your Apple Watch won’t turn on. Buying any phone replacement part on Amazon is usually a bad idea as they don’t work. Go with InjuredGadgets instead. They saved my Apple Watch after this battery and many others did nothing. ## Customer Reviews ### ⭐⭐⭐⭐⭐ Saved me from having to buy a whole new watch! *by J***Y on October 22, 2023* I replaced the battery a few days ago and I am quite impressed. I’ve had my watch on for a good 6 hours and am at 94%. I only charged it up to 50% yesterday and it lasted for over 10 hours before the 10% warning came on, and that was with quite a bit of playing around with to make sure all the functions were working properly.For some background, my watch had been originally running low on battery after 10 hours a day from a full charge and about a week ago while removing a bumper from the screen I had noticed the screen had detached from two of the four sides. The battery had swelled and needed to be replaced. I was devastated and the fact that Apple no longer fixes Series 1 was rubbing salt into a wound. I didn’t want to shell out the money for a new watch and my hubby told me to just buy one used….boo.I went onto YouTube and this looked like a much easier fix than I have done in the past. I’ve repaired iPod touch screens and a drive here and there on Xbox’s. The hardest part about this one was trying to get the battery to clip in and making sure it charged before sticking it down and gluing it in. I was able the get the battery in and strip of dry glue out without having to unclip the screen cables. I can’t comment on the 3M adhesive provided with the kit, I had used B-7000 glue. Anywho, this kit worked well for me and I’m hoping the battery will continue to do so. If not, I will update. ### ⭐⭐⭐⭐⭐ Good so far *by P***R on April 18, 2024* The screen of my Apple Watch Series 1 (7000) popped out because my original battery got inflated.Bought this kit and it included everything that I needed to ser it up properly.The new battery didn’t have any Apple specific branding, probably a third party battery. It fit perfectly and was easy to install.The battery was completely drained. I had to leave it charging for about 30 mins to just test if everything was OK before sealing the screen back in place.Everything was working as expected.Took a few hours for a full charge but now it lasts the same amount as when it was new.Hopefully it lasts long enough. ### ⭐ Battery is too old or bad upon arrival *by C***J on August 5, 2022* Screen had separated due to the known soft battery issue. Unit arrived as expected. Watched a couple of you tube videos before starting. Took a total of 15 min to change out the battery. Placed on the charger overnight and battery charged to 100%. Thinking everything was fine secured the glass and kept the watch on the charger again. After 2 days take the watch off charge and not 3 hours later the battery is dead. Recharge again and the battery did not last more than 4 hours. Now the battery is taking almost a full day to recharge back to 100% only to work for less than 3 hours and be totally drained. Totally disappointed in this product. ## Frequently Bought Together - HDCKU Battery Replacement Kit for Apple Watch Series 1 with Repair Tool Set A1803 and (1st Generation) A1554 42 mm - T-7000 15ml Super, Glass,Fabric,Craft, Adhesive,Puzzle, Glue Suitable for Repair Multipurpose High Performance Industrial Glue Semi Fluid Black Adhesive (15ML,1PACK) - Mustpoint for Apple Watch Series 1 42mm Force Touch Sensor Flex Cable --- ## Why Shop on Desertcart? - 🛒 **Trusted by 1.3+ Million Shoppers** — Serving international shoppers since 2016 - 🌍 **Shop Globally** — Access 737+ million products across 21 categories - 💰 **No Hidden Fees** — All customs, duties, and taxes included in the price - 🔄 **15-Day Free Returns** — Hassle-free returns (30 days for PRO members) - 🔒 **Secure Payments** — Trusted payment options with buyer protection - ⭐ **TrustPilot Rated 4.5/5** — Based on 8,000+ happy customer reviews **Shop now:** [https://www.desertcart.us/products/166529739-battery-replacement-kit-for-apple-watch-series-1-with-repair](https://www.desertcart.us/products/166529739-battery-replacement-kit-for-apple-watch-series-1-with-repair) --- *Product available on Desertcart United States of America* *Store origin: US* *Last updated: 2026-04-26*
