No, but it has recently been discussed by some people on and off-list.
I think I'd described this in Sonny's thread on external battery packs
(I remember having actually written "I *heart* waterproof"... ;=} ).

Apple manual doesn't say so. All they say is that you'll lose power:
(Internal pack + Battery Booster) < (first Internal Pack, then remove,
then Battery Booster)

A useful application for this could be when you're away from power
supply and need to run the Newton continuously. Run from internal pack,
then when that's down run from Battery Booster, and when internal is
recharged and this and Booster down to 50%, recharge Booster cells
(solar panel, fresh cells) and repeat when internal package hits 10%.

I've added the manual text (pretty short, recently discussed in Sonny's
thread on external power supplies) to the Wiki
http://tools.unna.org/wikiwikinewt/index.php/BatteryBooster . -- Which
reminds me: There's been many good discussions recently on NTLK, on GPS
map making and other stuff, hopefully these will be put up on the Wiki
slightly edited when the issues are resolved? Please?

...unless ye need to keep ye olde Newt running continuously longer that
  4x AA grant ye, or ye have to keep the setup in a waterproof casing
and can't safely change cells at will...

Thanks,

DJV.
