Battery, Warranty, and Service
The HP 12C Platinum is shipped with one 3 Volt CR2023 Lithium battery. Bat-
tery life depends on how the calculator is used. If the calculator is being used to
perform operations other than running programs, it uses much less power.
A battery symbol (
) shown in the upper-left corner of the display when the
calculator is on signifies that the available battery power is running low. When
the battery symbol begins flashing, replace the battery as soon as possible to
avoid losing data.
Use only a fresh battery. Do not use rechargeable batteries.
There is the danger of explosion if the battery is incor-
rectly replaced. Replace only with the same or equiva-
lent type recommended by the manufacturer. Dispose
of used batteries according to the manufacturer's
instructions. Do not mutilate, puncture, or dispose of
batteries in fire. The batteries can burst or explode,
releasing hazardous chemicals. Replacement battery
is a Lithium 3V Coin Type CR2032.
Installing a New Battery
The contents of the calculator's Continuous Memory are preserved for a short
time while the battery is out of the calculator (provided that you turn off the cal-
culator before removing the battery). This allows you ample time to replace the
battery without losing data or programs. If the battery is left out of the calculator
for an extended period, the contents of Continuous Memory may be lost.
