Cannot fully agree to that.
Nowadays the NiMH rechargeables are available with a capacity of up to 2000
mAhours or more. This is more than double the capacity of the original
battery pack. Thus the achieved extended operation time for the newt might
justify the need to charge them externally.
But there is also the possibility to modify the Battery tray in order to get
the NiMHs in the battery tray charged inside the Newt.

Or you get an old original battery pack and refurbish it:

Recently there was a long thread on LiIons:
to make it short: the conclusion was to stay with the high performance
NiMHs.
- Li-Ions have a different voltage and need some effort to match it to the
Newt
- Li-Ions are difficult to recharge, you need a special charger, so probably
there is no chance ever to charge them in the Newt
