Time-to-empty not accurate with dual-battery laptops.

[pcchou]

The time-to-empty displayed by this extension is simply adding up two battery's time-to-empty, but this value is higher than what it should be. Most dual-battery laptops will use a battery first, until it's empty, then another. When a battery is not on use, it's time-to-empty will become very big, because of a lower denominator.

The correct way to do this should be adding up the capacity of the batteries, then divide by the current power wattage.
