Power cycling before and after battery replacement

Power cycling before and after battery replacement

In my repair shop I don’t work on Apple Watches but I did replace the battery on a Series 1 for a friend who had purchased a replacement battery on his own from iFixit. The watch after having set unused for several months would power to the Apple logo then shut off. I told him I thought there might be more to it than needing a new battery, but since he had purchased one I would install it for him.
