The TI-82 STATS uses five batteries: four AAA alkaline
batteries and one lithium battery. The lithium battery provides
auxiliary power to retain memory while you replace the AAA
batteries.
When the battery voltage level drops below a usable level, the
TI-82 STATS displays this message when you turn on the unit.
After this message is first displayed, you can expect the
batteries to function for about one or two weeks, depending on
usage. (This one-week to two-week period is based on tests with
alkaline batteries; the performance of other kinds of batteries
may vary.)
The low-battery message continues to be displayed each time
you turn on the unit until you replace the batteries. If you do not
replace the batteries within about two weeks, the calculator may
turn off by itself or fail to turn on until you install new batteries.
Replace the lithium battery every three or four years.
Do not remove both types of batteries (AAA and lithium
auxiliary) at the same time. Do not allow the batteries to lose
power completely. If you follow these guidelines and the steps
for replacing batteries on page B
.3, you can replace either type
of battery without losing any information in memory.
Take these precautions when replacing batteries.
• Do not mix new and used batteries. Do not mix brands (or
types within brands) of batteries.
• Do not mix rechargeable and nonrechargeable batteries.
• Install batteries according to polarity (+ and N) diagrams.
• Do not place nonrechargeable batteries in a battery
recharger.
• Properly dispose of used batteries immediately. Do not leave
them within the reach of children.
• Do not incinerate batteries.
