Why does iBook battery crash OS at 48% but holds charge?
I bought a replacement battery for iBook 14" G4; it came out of the box charged to 54%; charged it to 100% so I could run it out to sleep and calibrate it; it crashed the iBook at 48% but held the charge. I can't calibrate it because I can't run it out. It did the same thing on our other 14" iBook.
Is this a good question?
