I'm not sure, but I think that 1000 mAH is pretty low charge, as I think
I've read that some people were using 1500 and even 1600 mAH NiCADs. So,
that may explain why the Newton displays a charge of 90% initially. I don't
remember what was the original charge of the NiCAD recharging pack, but you
can assume that the power manager they put in the Newton was designed for
their power characteristics. So, if you put higher capacity NiCAD, the
Newton will erroneously provide charge information. The same will happen if
you put lower capacity NiCAD, the Newton will assume that they aren't fully
recharged, even though they are.
Frank Gruendel might confirm this more precisely than me...

[common] Software that has some important functionality deliberately removed, so as to entice potential users to pay for a working version. 2. [Cambridge] Variety of guiltware that exhorts you to donate to some charity (compare careware, nagware). 3. Hardware deliberately crippled, which can be upgraded to a more expensive model by a trivial change (e.g., cutting a jumper). An excellent example of crippleware (sense 3) is Intel's 486SX chip, which is a standard 486DX chip with the co-processor diked out (in some early versions it was present but disabled). To upgrade, you buy a complete 486DX chip with working co-processor (its identity thinly veiled by a different pinout) and plug it into the board's expansion socket. It then disables the SX, which becomes a fancy power sink.
