How long are you getting after a "Battery Low" warning? Do you hear the
"Battery Critical" warning. We get thrown out either immediately the
"Battery Low" sounds or even before that, perhaps. I have no real idea
at what percentage it's dying yet and I still can't calibrate.
I know you had trouble getting calibration to start. Can you recall at
what point of the battery cycle you actually achieved this?

Hi, Carol. I agree. Probably not worth sending the unit in. Just more of
an
annoyance. I still can get it charged to 100 percent and as long as you
know the battery dies at just under ten percent, you know what to
expect.
Also,
losing that ten percent means that you will not get 10 to 12 hours of
use
out of an MPower. Again, not a big deal as long as you are aware of it.
It
just means you have to charge up more often.
It would be nice if these guys would come out with a car charger or some
kind of external battery charger.
