Hi everyone, I have the last model of the MBP that had the removable battery (so I think 2008), recently whenever I run it on the battery it shuts off at pretty high percentages charged, for instance it just shut off and was at 60% charge. This doesn't happen when it is plugged in with the battery in or out (I frequently take the battery out in an attempt to save it when I'm at my desk anyway). I'm going to guess this is just a battery problem and mine is going bad, even though istat says 85% health. Anyone else having this problem? Thanks for your time!
