Aero battery-status battery animation


With the utility from Compaq softpaq SP0993 it is possible to determine the battery level in over 30 steps.

I have written down the values during a complete discharge and have drawn a little diagram. - 96kB GIF
As one can see it looks the same as the voltage-curve of the Battery itself.

I have found out that dots of the Battery-level popup-feature follows those values:

Dots shown: 012345
CHARGE.COM - level: ...131132..136137..141142143,144145...

A fully charged battery has about 1,45V and the charge-level is about 166.
At a level of 130 the aero goes to hibernation, the battery should then be at a voltage level of 1,0V or a little higher.

So I think the real voltage of the battery could be computed with this formula:

Ucell = 1.0V + (level - 130) * (1,45V-1,0V) / (166-130)

It is also possible to write a little program that computes the time it will take until the battery is empty, according to the current amount of power needed.
