Ok, so using Coconut Battery 2.5.1, I can see my battery capacity is dropping fairly rapidly every couple of days on my 15" PowerBook G4. This is one of the replacement batteries Apple offered out during the exploding battery panic. Is anyone else noticing drops like this? I calibrate literally every 3 days, sometimes once a week. Attached, is a screen grab from the table of results that i've been saving on Coconut Battery: I'm a little concerned... Rich.
