Fujitsu Lifebook T580 - 6-Cell Battery And Run Time
Gear: Fujitsu LifeBook T580, Convertible Tablets, BatteryBar Pro, 6-cell T580 Battery, Battery Charging Station.
Fujitsu gives you two battery options with the Fujitsu Lifebook T580. The advertised runtimes are: 3-cell will last 3:25 hrs, the 6-cell will last 6:50 hrs. This of course is not quite the "real" numbers, it is an "up to" estimate. You are very unlikely to achieve those numbers. Just about every company that sells PCs does this hideous thing. So what's the real run time?
With the 6-cell battery you can expect about 3 hours of battery life. This is based from a few weeks of use with the system at above medium brightness level, Google Chrome and a few videos playing every once in a while.
As you may have noticed the Microsoft battery meter is very unreliable. I use a program from Osiris Developmet called Battery Bar, which has a free and a Pro version. It measures several "runs" and then estimates an average.
I highly recommend having the 6-cell battery. I'm not sure what the 3-cell would give you... but most likely it would be a waste.
