Chosen Solution

I just completed the guide for replacing my battery using an official iFixit Battery Kit and it’s not being recognized. Only powers on when the magsafe power adapter is plugged in.No battery icon appears in the top toolbar.The magsafe adapter light glows orange.My System Report says there’s no battery installed.When I plug my old battery back in, it still works and the battery icon shows up.I’ve reset the PRAM and SMC multiple times. What should I do? My suspicion is that iFixit sent me a dead battery. Update (11/08/2020) So the strangest thing… as I’ve been waiting for my replacement battery, I’ve kept my laptop plugged in for about two weeks on and off since I first posted this question. I travelled from the high dessert to the ocean and when I booted up my computer, the battery icon showed up finally and showed 55%. So somehow along the way, my new battery started working. Here is the screenshot from Coconut. I’m wondering if I should trust this battery or if I should install the replacement. I will probably test out the replacement and compare using Coconut Buddy. Thoughts?

Well I guess that proves the battery is bad ;-{ You’ll need to contact the iFixit store for a replacement, sorry ;-{ Contact iFixit Customer Support
