All my ham radio gear use Lithium battery packs and they perform fantastic for that application - high current during transmitting with a fairly constant voltage. But they give almost zero warning. I will get a warning if I am only receiving (i.e., low current) for several minutes before they shutdown. But if I'm transmitting, then they just abruptly shut down and I find myself talking to myself instead of transmitting.

Not sure how much (if any) warning they would give on the Omnibook. I use the non-rechargeable Energizer Lithium batteries on my OB. I find that there is really no warning - the OB just beeps and instantly shuts off. No loss of data - but then I've never had it shut down while writing.

That's sort of why I tend to avoid lithium primary cells too (although those don't seem to tank quite as sharply as the Kentlis apparently do). But they certainly do reduce the overall weight of the device, which is a nice side effect.

Lately I've been using DataPerfect on my palmtop and OB, and being a network-capable database program, it's pretty chatty with disk I/O, out of necessity. It would definitely be a game of Russian roulette whether it shuts down in the middle of a record/index update and corrupts the database. Think I'll probably shop around for some good NiMH kit later; the warning on those is short too compared to alkaline, but usually plenty.
