Hey guys,

I don't actually have any problems with my macbook battery but was just wondering if my battery life is normal.

I'm using a Macbook5,1 (late 2008 aluminium unibody macbook. not pro)

and under iStat I'm getting:
Health: 93%
Cycles: 400

and under system profiler (I know it says condition is normal :p) I'm getting:

Model Information:
Serial Number: 6N837F3U13CB
Manufacturer: SMP
Device name: bq20z951
Pack Lot Code: 0000
PCB Lot Code: 0000
Firmware Version: 002a
Hardware Revision: 000a
Cell Revision: 0100
Charge Information:
Charge remaining (mAh): 3789
Fully charged: No
Charging: Yes
Full charge capacity (mAh): 3828
Health Information:
Cycle count: 400
Condition: Normal
Battery Installed: Yes
Amperage (mA): 205
Voltage (mV): 12558


Was just wondering if this is healthy statistics for a 21 month old battery :)

Cheers!

Ahh good! I had stopped using my Macbook all the time since i got my iPad :eek: and when i checked the battery it was away down to 88% but a good calibration brought it back up to 95% but it keeps going between 93%-95%

Oh really? I take it youve calibrated and reset SMC? :eek:

I hope my battery lasts another 2 years or more, which is when i'll start thinking about a computer upgrade :) i love my macbook :D i don't need no stinking i3/5/7 processors :cool: jkjk.
