Jean,
If you get a message which indicates that you aren't able to get an
accurate percentage on your battery, enter the command again. It should
give it to you the second time around. I wouldn't let it worry you at all.

Would it be technically possible to have a "fast or rapid" discharge
feature for when the battery needs recalibrating? I've also gotten that
message that the battery neeeds recalibrating, but so far I've ignored it
because I don't want to be without the unit for the hours and hours it takes.

Subject: [Braillenote] mPower calibration
Hi, all. This morning when I checked my battery status after exercising
with the stopwatch, I got the message that the status couldn't be given
because the battery needed calibrating. I noticed that it was four weeks
to the day since I got my mPower, so I'm wondering if the unit is
programmed to say it needs calibrating every four weeks. Anyway, I
decided to calibrate it while I was at work. I started the initial
charge at around 7:36 this morning, and when I got home about 5:15, it
was merrily chattering away, but not saying anything about battery low or
battery critical, which didn't surprise me. My old BN would take about
10 hours to discharge, so I figured the mPower would be about the same,
if not a little longer. It was still chattering when I went to eat
dinner, and when I came back in here a couple minutes ago, it was
quiet. I hit the space bar, and it said the discharge process took 9
hours and 26 minutes. The display said "battery is low". So my
impression is that when the mPower says "battery is low", it means "the
battery is on its last gasp and needs to be charged
yesterday". <grin> So I'm wondering a couple things: Is it a bad sign
that my unit stopped talking after only 9 hours and 26 minutes? In a way
I'm delighted, as I didn't want to hear it chattering all evening, and
hopefully it'll charge quickly and I can use it. I'm also wondering if I
should turn it off now that it's recharging, or if I should wait until it
tells me it's all charged. I guess I'll find out.
So those are my calibration thoughts and experiences.
Oh yeah; one thing I noticed after it first told me it needed
calibrating, was that the next time I turned it on, it gave me a
percentage when I checked status. Is the need-for-calibration message
supposed to be intermittent, or was it possibly a false message?
