This is a perfectly normal value.

The last one I describe, which is the most brutal one. It will set
the Newton back to factory condition, apart from the OS upgrades that
are installed (which can't be reset any "normal" way).

Weird. In my case it's usually the other way round ;-)

This might of course save your problem, but as a matter of fact
you shouldn't be having this problem in the first place.

Yes. Very much so. All cards suck current, some more, some less.
Communications cards have a tendency to suck more current than e. g.
cards. Some can discharge a fully discharged battery within hours.
are some other ways to waste current, by the way, like e. g. having
"Receive beams automatically" in the Prefs.

Some things you should know...

1) It sometimes takes a while before a Newton that has just been
switched on
updates its battery capacity value. I've had Newtons that took almost
minute to do this. So if your "charger" Newton reports 100% although
battery has been charged days or weeks before, this might actually not
be correct if you check this value immediately after powering it up.

2) The Newton is somewhat dumb if you change the date during a charge
cycle. It sometimes draws the conclusion that the cycle should have
finished long ago and simply stops it. Although 100% might be
the cycle might not be finished, because after reaching 100% the
charges happily on until the cells' temperature exceed a certain

3) If you do not want to use the sledgehammer yet, try *almost* using
on both Newtons before you swap a battery. You should start with Reset
as described on my site, but press "No" when the Newton asks its
"Do you really want blabla..." questions. After that you should wait a
minute and then check the reported capacity.
Do this BEFORE you remove the battery from the charger Newton and
AFTER you plugged it in the other Newton.
