The amount of time required to fully charge the battery may vary, but charging
normally takes about six hours. It is not necessary to remove the TI-Nspire™
Rechargeable Battery from the handheld to recharge it. The handheld operates
normally while it is attached to a charging source.
Recharging a Battery from a Computer
To recharge a handheld from a computer, a TI-Nspire™ USB driver must be installed.
USB drivers are standard with any TI-Nspire™ software, which includes:
• TI-Nspire™ CX Premium Teacher Software
• TI-Nspire™ CX CAS Premium Teacher Software
• TI-Nspire™ CX Student Software
• TI-Nspire™ CX CAS Student Software
To download software that includes a driver, go to education.ti.com/software.
Understanding the Priority of Power Sources
When the TI-Nspire™ Rechargeable Battery is fully charged, the handheld draws power
in the following order:
• First, from a connected external power source, such as:
- A computer connected through a standard USB cable
- An approved wall charger (sold separately)
• Second, from the TI-Nspire™ Rechargeable Battery
