Why is the replacement battery not consistently recognized?
I had a crappy battery that would last less than an hour on my 2012 Macbook Pro. I ordered a replacement kit from iFixit and followed their guide for swapping batteries. My new battery is fine for a while, but will eventually not be detected within a couple hours or days. I have removed the battery and reinstalled the same one twice, and each time, it’s fine for a bit, but within hours or days, it’s undetected again. What’s going on, and how do iFixit (ha)?

With battery detected, not plugged into charger:

Is this a good question?
