When fully charged, a LabQuest 2 will run an entire school day in the most common use scenarios. Although warranted for one year, the LabQuest 2 battery should last for three years or more depending on how it is used.
If you are having problems with your LabQuest 2 battery, follow the troubleshooting steps below.
1. First use of LabQuest 2
LabQuest 2 ships with a plastic tab that prevents the battery from making contact with the LabQuest unit during shipping. You need to remove this tab in order to charge the battery. For more information, see TIL 2692: My brand new LabQuest 2 battery doesn't work.
2. Check software version.
We recommend you update your LabQuest 2 to the most recent version available. Instructions on how to download and install the free update are posted at http://www.vernier.com/support/updates/labquest/labq2/
Note: When having battery issues, we recommend you recalibrate the battery monitor after applying the update.
3. Recalibrate battery monitor.
a. If LabQuest is on, shut down the LabQuest by choosing Home / System / Shut down.
b. Remove the battery and disconnect the AC power adapter.
c. Wait at least one minute.
d. Connect the AC power adapter.
e. Press the power button to power on the device and wait for the device to boot.
f. Return the battery to its original position in the LabQuest.
g. Let the battery charge for 12 hours.
4. Run a battery test.
If none of these describe your problem, it is possible that the battery is no longer usable and may need to be replaced. To test your battery, see TIL 2921: How do I test the battery life of the LabQuest 2?
5. Replace the battery, if necessary.
