Shelf life of ifixit battery kit?
I was getting battery error messages any time the power adapter wasn't plugged in. State of charge was stuck at 1% or went from 100% to 1% soon after the adapter was unplugged. The battery preferences tab said that it needed service. So I ordered up the iFixit replacement kit.
Step one: drain the old battery. Well, darn if it didn't run for nine hours of writing, browsing and reading on "1% charge." Seems as if it's more of a calibration problem than an end-of-life problem. Though the preferences tab still says it needs to be serviced. There appears to be quite a bit of life left in the old battery after all.
So my current dilemma is whether to replace the battery anyway (some rainy day when I "get around to it"), hold the Ifixit kit in reserve (for months? years?) or return it. How quickly will the new battery degrade, just sitting in its original packaging?
Is this a good question?
