I heard a story that might be apocryphal that the Voyager series were specified to not need a battery change for "at least a year" and it was misinterpreted as 1 year of power-on time.

But both my 32s and 35s both had "pretty good" battery life.

I bought my HP-15C in 1987. It only recently got its third set of batteries.
