Battery Problem

Hi

I just found there's something wrong from the 'battery infomation'.

It showed the 'Design Capacity' of the 9-cell Li-ion Battery is 84.24 Wh, but the 'Full Charge Capacity' is only 80.38 Wh, which is about 4 Wh short.

Does it mean my battery is in bad quality? and would the capacity keep going down? (I have a secondary battery and the 'Design Capacity' & 'Full Charge Capacity' match each other). And could I ask Lenovo replace a new one for me for that reason.

I bought my T60p 6-weeks ago and the Cycle count is only 6.

Thanks~

Not unusual. Your battery will start losing capacity from day one. Relax and just enjoy your laptop. There is nothing wrong with your battery.

Agree with Greg -- but another point is that the full charge capacity is estimated; the battery cannot provide the info directly. If you want to ThinkPad to recalculate the estimate for higher accuracy, you'll need to do a complete discharge cycle (ie turn off low-battery alarms and allow it to run to zero).

Anyway, six cycles in six weeks -- you must not be using the battery very much! I'm up to 754 cycles on my X31 ...

I owned a T43 for five months, during which I used only two cycles!

Now that is a feat

I'm running a cycle a day by now

How long does it last now? And what are the numbers? (actual vs designed capacity)
