That phrase "but they look about right" is the wrong
way to approach things with a Newt. The Newt is a
different beast and if you aren't 100% sure, and can
not afford to destroy your Newton, don't guess...be
100% positive before you mess with the internal
workings of your Newt. That said, do not use any of
the batteries on the page you posted! If you do, you
will have a paperweight. (a rather warm paperweight
for about 5 minutes too!)
The reason being is that these rechargeable lithium
batteries are the wrong voltage! The average AA
battery (alkaline/carbon configuration) puts out 1.5
volts per cell. Rechargeables usually put out
considerably less. This makes the Newt, with 4 AA
batteries run on 6volts. If you place 4 of these
lithium rechargeables into your Newt, you would end up
with 14volts...not a good thing.
OK, now that said...through experimentation, you
MAY...I reitterate...MAY be able to configure these
rechargeables in a parallel/serial way to allow the
batteries to supply the 7.4 volts and still use all 4
batteries. This would be something like 2 batteries in
series, and place another 2 batteries in series in
parallel with each other. (remember, series increases
voltage, parallel increases current) and since these
lithiums have a high current already, you might be
able to get them to work...but with current battery
technology having proven its self on the newt, it's
not worth the risk, and I couldn't stand to see a Newt
go up in smoke on an experiment...
