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 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.
Warning
There is the danger of explosion if the battery is
incorrectly replaced. Replace only with the same or
equivalent type recommended by the manufacturer.

To prevent memory loss, never remove two old batteries at the same time.
Be sure to remove and replace the batteries one at a time.
