I am getting a "Battery Fault!!! Replace Battery" message on LabQuest.

In some cases, it’s possible that the LabQuest Battery Monitor applet may incorrectly report that the battery is defective and display a message indicating that there is a battery fault. There is a good chance that the message is incorrect and that the battery is actually okay.

Check the version of the LabQuest App by selecting the Home icon, then Control Panel, then System Information. If you are not running the most recent version of LabQuest App, download and install the free updater from our web site:
