I'm afraid I disagree. NiMH's have, just as NiCad's, an operating voltage
of 1.2 volts. Thus 100% capacity means 4.8 volts or more for NiMH's and 6.0
volts or more for alkalines (the latter having an operating voltage of 1.5
volts).
NiMH's shouldn't normally be discharged below 1.0 volts, so 0% capacity
means
4.0 volts for NiMH's. For alkalines this doesn't matter as you throw them
away
anyway, so here 0% means the lowest voltage the Newton will safely work
with.
On my 120 and 130 this is about 3.6 volts.

After an initial charge loss (which is about 15 percent within the first 24
hours) they lose 15...20 percent per month at room temperature.
This is approximately doubled every 10 degrees celsius increase in
temperature,
that's why it is a good idea to charge them and store them in the fridge if
not used.
