Sonuç

If possible, turn on your device and test your repair before installing new adhesive and resealing.

Secure the new battery with pre-cut adhesive or double-sided adhesive tape. In order to position it correctly, apply the new adhesive into the device at the places where the old adhesive was located, not directly onto the battery.

To reassemble your device, follow these instructions in reverse order.

For optimal performance, calibrate your newly installed battery: Charge it to 100% and keep charging it for at least 2 more hours. Then use your device until it shuts off due to low battery. Finally, charge it uninterrupted to 100%.

Once I had the correct tools and replacement battery, fixing was easy. Tyvm!

Jeremy Salazar - Yanıt

One question, where can I find an authorized battery for this watch? or one that you highly recommend. Thanks.

**Edit - Your store doesn’t have a 45mm battery for my Galaxy Watch 3. Only 42 and 46.

Gilberto Garcia - Yanıt

The 42 and 46 mm models are the first Galaxy Watch sizes. We ’re working on getting the Watch3 batteries and parts but it may take some time.

Hi, is it possible to put the battery from samsung watch 472mAh, on samsung watch 3, instead of 340mAh?

Andrey Irnazarov - Yanıt

Hi Andrey, short answer is no—although basically a good idea. But even if you cut the battery contact plate to fit (cut off the part with the alignment hole) its polarity is inverted. The Watch3 contact plate has -/+ (noted under the cable) whereas the original has +/-. Also the original Galaxy Watch battery is much bigger than the one in the Watch3. So it won’t fit inside the recess. Here is an image with the Watch3 battery on top of the original battery.
