Batteries
The HP-16C is powered by three batteries. In “typical” use, the
HP-16C has been designed to operate six months or more on a set of
alkaline batteries. The batteries supplied with the calculator are
alkaline, but silver-oxide batteries (which should last twice as long)
can also be used.
A set of three fresh alkaline batteries will provide at least 80 hours
of continuous program running (the most power-consuming kind of
calculator use*). A set of three fresh silver-oxide batteries will
provide at least 180 hours of continuous program running. If the
calculator is being used to perform operations other than running
programs, it uses much less power. When only the display is on—
that is, if you are not pressing keys or running programs—very
little power is consumed.
If the calculator remains turned off, a set of fresh batteries will
preserve the contents of Continuous Memory for as long as the
batteries would last outside of the calculator—at least 1'% years for
alkaline batteries or at least 2 years for silver-oxide batteries.
The actual lifetime of the batteries depends on how often you use
the calculator, whether you use it more for running programs or
more for manual calculations, and which functions you use.*
The batteries supplied with the calculator, as well as the batteries
listed below for replacement, are not rechargeable.
*Power consumption in the HP-16C depends on the mode of calculator use: off (with
Continuous Memory preserved); idle (with only the display on); or “operating” (running
a program, performing a calculation, or having a key pressed). While the calculator is
turned on, typical calculator use is a mixture of idle time and “operating” time.
Therefore, the actual lifetime of the batteries depends on how much time the calculator
spends in each of the three modes.
