My old 48Wh 4-cell battery wasn't lasting long enough (1.5hrs), so I purchased a 86.5Wh 9-cell battery a few days ago.
However I noticed the Windows low battery indicator came on quicker with the new battery (after about 1hr)!!!
So I downloaded BatteryMon and looked at the battery characteristics:
This pic shows the battery fully charged, with the AC adapter connected. I don't understand why the full-charge capacity is so much lower than the design capacity and the current capacity.
As soon as I unplug the AC adapter however, the current capacity jumps down to:
And within 1 minute it's chaged to this (notice the 57W discharge rate!):
It continues to drain until it reaches 6% (after about 1hr), but the weird thing is it will stay at 6% for well over another hour!
What's going on? With the old battery the discharge rate is only 21W!
Thanks,
Gareth
