The original batteries in my HP48 (week code 3006) lasted about 6 months
with moderate use, a daily alarm, and occasional kermit.
My HP28 batteries seem to last a couple of years (smaller display, no
rs232, no IR input, slower clock, etc.)
.
One thing to watch for is shorts or high leakages in memory modules.
A CMT 32k module for the HP71 developed a short after doing fine for
years.
