ALL INFORMATION BASED ON CURRENT SAGER LAPTOP/BATTERIES:
Pmax is obtained by using the inverter (assumption of the laptop not draining more power then the inverter can provide is reasonable)
Pmax=v*I
Pmax=20*6=120W
120W-45W(QX9300)+130W(i7)=205W
----------------
| Pmaxi7=205W |
----------------
12-Cell Battery pumps out 11.1V
P=v*I
P=11.1v*8.8A=97.68W/hour
97.68/205= .4764878 hours = 28.589268 minutes
------------------------
| Tfullload= 29. minutes |
------------------------
Approximately 30 minutes under full load doesn't sound that bad. If under low load (i.e. watching a LQ movie//browsing the web and using flash), it'll probably be pushing an hour or so...
Anyone actually have any information on non-theoretical real-world battery life tests?
