Unused 3yo battery Fix Kit - has it expired?
I bought an iFixit battery Fix Kit for my MBP 15” (Retina, Mid-2012) 3 years ago and kind of just forgot about it in the back of my cabinet.
Now I’d like to use it.
Do you think the battery has become defect from not being used? Also, could the iFixit adhesive & adhesive remover have gone bad?
Is this a good question?
