Use NiMH batteries, but keep a pair of Lithiums just in case 100/200LX
Here is what I consider my ideal battery setup. One pair of Nickel Metal Hydride (NiMH) batteries that are charged once a week as a routine and one pair of Lithiums as a backup. Since the NiMHs do not have Memory Effects they are easily topped off within the standard 6 hour charge weekly. The Lithiums are great backup batteries as they hold their charge for years. Alternatively if you want to charge externally, two sets of NiMHs swapped weekly will work fine.
[Note: Neither NiMH or Lithium batteries are officially approved by HP for use in HP Palmtops.]

Some Palmtop users have found it difficult to get NiMH batteries. Two sources of NiMHs are:
