Here are the stats from my MacBook Pro (also mid 2009, 13-inch, original battery): Temperature = 2990 CycleCount = 488 DesignCycleCount9C = 1000 DesignCapacity = 5450 MaxCapacity = 4804 WearRatio = 88% CurrentCapacity = 4804 ChargeRatio = 100% Voltage = 12568 Amperage = 253 InstantAmperage = 88 TimeRemaining = 0:8 AvgTimeToFull = 0:8 I seem to be missing the InstantTimeToEmpty and FullToEmptyTime data. Reading your script, that tells me the values are "None" but not why that is. I'm also apparently 8 minutes from an empty battery, even though it's fully charged. Do you know why this is?
