Figure 8-2. Removing the NiCad Battery Pack
Note
The ac adapter/charger will not power the test tool when the battery
pack is removed.
Internal Lithium Backup Battery
A lithium battery maintains the test tool’s memory contents when you remove the
NiCad battery pack. The memory contents maintained are the stored Autotest
reports, all SETUP settings, self-calibration and NVP calibration data, custom
cable configurations, and the report identification information.
The lithium battery lasts about five years if you always keep the main battery
installed. Removing the main battery pack for extended periods shortens the life
of the lithium battery.
