Precautions for Rechargeable Batteries

•

Do not expose batteries to temperatures above 140¡F (60¡C).

•

Do not disassemble or mistreat batteries.

•

Use only the charger recommended for the cell or battery, or the one that was provided with the original equipment.

•

TI recommends that you use the USB cable included with this calculator. If you choose to use a third-party power adapter with the TI-supplied USB cable, you should use an adapter that meets applicable safety and operational standards and certifications, including UL and CE certifications.

Take these precautions when replacing rechargeable batteries:

•

Replace only with a TI approved battery.

•

Remove the cell or battery from the charger or alternating current adapter when not in use or being charged.

•

Use of the battery in other devices may result in personal injury or damage to equipment or property.

•

Do not mix brands (or types within brands) of batteries. There is a risk of explosion if a battery is replaced by the wrong type.

Disposing of Batteries

Do not mutilate, puncture, or dispose of batteries in fire. The batteries can burst or explode, releasing hazardous chemicals. Discard used batteries according to local regulations.
