Charging TI-Nspire™ Rechargeable Batteries
The charging process starts automatically when a handheld is placed into a slot if the docking station is connected to a power source. Otherwise, the charging process starts when the docking station is connected to a power source.
It is not necessary for the docking station to be connected to the teacher computer to charge the rechargeable batteries in the handhelds.
Determining Status of Batteries in a Handheld
The LED lights under each slot on the docking station provide basic information about the status of the TI-Nspire™ Rechargeable Battery or AAA batteries in the handheld. Status of batteries in the handheld is reported in the following priority:
|
•
|
If a handheld has a rechargeable battery, status for the rechargeable battery is always reported even if the handheld also has AAA batteries. |
|
•
|
If the handheld only has AAA batteries, the status of the AAA batteries is reported. |
|

To determine the status of the handheld’s batteries, look at the Battery Status LED indicator for the slot under the handheld. The Battery Status LED Indicator is located to the right of the battery symbol ():
|

Red indicates battery is low with less than 25 percent power |
|
•
|
Yellow indicates battery power is between 25 and 75 percent |
|
•
|
Green indicates battery power is greater than 75 percent |
|

The handheld is not seated correctly. |

The docking station is not connected to a power source. |
Learning More about Battery Status
Additional information is available in the Content Workspace if using TI-Nspire™ CX Premium Teacher Software, TI-Nspire™ CX Teacher Software, or TI-Nspire™ CX Navigator™ Teacher Software. You can view the status of both the TI-Nspire™ Rechargeable Batteries and the AAA batteries in connected handhelds.
For both rechargeable batteries and AAA batteries, status levels are reported as they are on the handheld:
|
•
|
Critical, low (two to ten percent), 25, 50, 75, or 100 percent charged. |
|
•
|
Percentages are presented in black text unless the level is critical. Red text indicates the battery power is critically low. |
|
•
|
Two dashes (--) indicate the handheld does not have a rechargeable battery or AAA batteries installed. |
Troubleshooting
If the recharge fails:
|
•
|
Make sure the handheld is seated properly in the slot. Batteries are not charged if the connector on the handheld and the connector in the slot are not aligned. |
|
•
|
Check the connector on the handheld to ensure that it is clean. If there is build-up on the handheld’s connector, you can remove it with a clean, dry cloth or a pencil eraser. Never use wet cloths or solutions of any kind. |
