Where did you check the "98%" reading?

i use istat pro, checked on the "About this Mac" menu but don't have this feature.

I dont know whether this app reliable or not.

well that's 2% drop for 6 cycle. Maybe you should monitor it closely. Have you done a calibration?

If you are not happy with it, you should call AppleCare on office hour and make a case, see if they can offer you an exchange.

cant really said without doing some check.
ask the owner (seller) to install coconutBattery, and check from there.

Okay.. i removed the istat pro and install istat nano.. it give me a reading 97% health. Seems like this widget reading do not tallied to one and another.

Get coconut battery

Try to do a battery calibration and see

Thanks guys.. done calibrating. Batt increased to 99% and then the subsequent charging indicated 100%. Problem solved.

i did battery calibrating but then when powered up (with 100% battery) it only last 3hours and below ..
any mistake ??

lol i just got my mbp 2 days ago with 4 cycles my batt is down to 98%

if you used it plugged in,its normal.mine is also like that,only 5 cycles for 3 weeks now.
the 97% is because its plugged in,and the battery is fully charged.its like the adapter controls the current so the battery doesnt overcharge.like charge-discharge.

@mkaz You have to tell us more. Which model is your Mac? How old is it?

@insane.gamer, I hope you read the replies above. Tried calibrating the battery?

wei: mbp 13" 2010 bought dec2010 ..

Okay, have you install the app mentioned like iStat Pro or Coconut Battery? What is the reading you get for Charge Cycle & Remaining Capacity?

Battery life highly depend on what you running on it.

For example:
Running 3-4 bar screen brightness and nothing connected over USB/FireWire. Only doing word processing is definitely will run longer than have full brightness, WiFi on, Bluetooth on, playing music, watching youtube with external hard drive connected.

How do you "calibrate" the battery? I don't understand :/
