Apple Watch series 2 possible battery leak?
I've just bought broken watches. The guy sad that they stopped charging. I thought that the battery is the problem, so I bought them. After opening the device I immidiately noticed green, white or maybe blue type of matter. On first sigh It didn't look like it’s corrosion. Have you ever seen this? Is it battery acid? Any possible ideas how to fix it?
As you can see, that greenish matter is only on the battery connector cable, on the plastic cable, so in case of water leak I would expect corrosion on metalic pieces. Secondly, the green matter is only on the spot, where the battery cable touched the device, thats why I think it’s just battery acid, not water. When water leaks into device its characterstic would case leaking and making corrosion all over the whole device. Any tip for cleaning this possibly acid matter?
