Kurt - NiCds are all I use in my 8201a's - They both act identically to yours.
Years ago I rearranged WATCHDOG.CO to display elapsed-time where the M$ blurb usually appears, which scratched my itch for a little more battery certainty. I reset it when I change batteries - Not perfect, but good enough. If you pursue tweaking the battery light circuit I hope you write it up...
