My battery connector looks like the energy star (6+12 pins) but on the motherboard says “apple inc 820-2279-A “ and no ‘energy star’ is written. I assume I should get the energy star model because is identical to mine. However, iFixit points to follow what is written on the board. So, something wrong here…
I replaced a swollen battery. It came with no charge. So, after about 2-3h, it was 100% charged. Watch works again! thanks
The guide looks incomplete to me. Adding a picture after pulling the battery connector out would help to understand better the last step. It took a while to figure this out. Also, links to the spare parts would be helpful.
