If it reboots by itself there's something wrong, but the 'Newton restarted
because all power was removed' is actually "normal" with some memory

Don't bother, if you're any good with a soldering iron (and I'm talking just
basic soldering skills this time) you can replace the battery pack if it
would ever go bad.
Just buy 4 NiMH 1200 mAh batteries with soldering lips on them, open the
eMate with a torx 8 screwdriver (which you already have if you installed the
memory upgrade) take apart the battery pack (quite simple) and remove the
electronic components (sorry, been a while that I've done this, don't
remember exactly what they were) resolder everything on the new cells,
reconnect and you're done.
BTW, don't forget to make a backup (or two ;-) before you do this, I think I
lost all info on my eMate, but I'm not 100% sure about that anymore.
To do all this is actually so easy that to develop a replacement battery
pack would never be a good business idea, don't forget that a new battery
pack will be good for probably another 3 to 4 years and the work involved
will maybe take half an hour the first time.
