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.
