Regulatory Information
Batteries
The HP 15c is shipped with two 3 Volt CR2032 lithium batteries. Battery
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.
Low-Power Indication
A battery symbol (✱) shown in the lower-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 batteries as
soon as possible to avoid losing data.
Use only fresh batteries. Do not use rechargeable batteries.
Warning
There is a danger of explosion if batteries are
incorrectly replaced. Replace only with the same
type of battery or with equivalent batteries (as
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
batteries are two Lithium 3V Coin Type CR2032.
