I've got an 14" iBook purchased in June 2004. It only has 51 cycles. I've lost 28% capacity in the battery. The battery is 4600mah and I'm at 3302mah now. Do I have defective battery?

Please post your capacity using this command in the Terminal window.

ioreg -l | grep -i IOBatteryInfo

Here are my results

JRiBook:~ Kelvin$ ioreg -l | grep -i IOBatteryInfo
| | | "IOBatteryInfo" = ({"Capacity"=3302,"Amperage"=0,"Cycle Count"=52,"Current"=3287,"Voltage"=16701,"Flags"=8 38860805,"Absolut$

Thanks,

Kelvin

I got my ibook in July 2004.
Capacity is 4144/4600 or 90% of original capacity.
When I checked earlier this month it was at 4400/4600.

I am using capacity meter to check. terminal said 124 cycles by the way.
