Replaced battery not giving/receiving power
I am currently repairing an Apple Watch Series 4 44MM by replacing its battery but none of the replacement batteries I have received from ifixit give any power to the device or allow for charging. When charging the Apple Watch with one of the replacement batteries it does get warm.
Ifixit has sent me a replacement battery for the first defective battery
I checked it with another Series 4 44MM and still no luck. When I try the original battery it does turn on.
What options do I have left?
The following solutions are tried without luck:
- Using the original charger.
- Removing the battery, holding the crown for 15 seconds
- Holding the power button and crown for 20 seconds
- Put a battery in and charge it for two hours.
