> (macbook still at 4+ hrs on full charge and it is 1.5 yrs old)

My MacBook Pro, mid-2009, original battery:

    Temperature = 2982
    CycleCount = 591
    DesignCycleCount9C = 1000
    DesignCapacity = 5450
    MaxCapacity = 4814
    WearRatio = 88%
    CurrentCapacity = 1514
    ChargeRatio = 31%
    Voltage = 11077
    Amperage = -694
    InstantAmperage = -661
    InstantTimeToEmpty = 2:17
    TimeRemaining = 2:11
    AvgTimeToEmpty = 2:11
    FullToEmptyTime = 6:56

(this is from a python script of mine [0])

Close to three years of daily, heavy use. The thing just doesn't want to die (crossing fingers).

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?

Amperage is positive: you're charging. So:

- TimeToEmpty makes no sense.

- you're 8 minutes to full.

Doh! Thanks for the update.
