Working with Batteries
Battery screen displays several kinds of information:
• Temperature—the internal temperature of each battery as
measured by a sensor embedded in each battery
• Voltage—for each battery cell stack as measured by each battery’s
sensor
• Run Time to Empty—while using external power, External DC
Power is displayed; while using battery power, the predicted
remaining battery run time is displayed in minutes at the present
rate of discharge. The instrument mode you select affects the
discharge rate, which determines the run time to empty.
Stimulus/Response uses the most power. The remaining modes use
the least power.
• Fuel Gauge Error—the present accuracy of each battery’s fuel
gauge or remaining charge capacity. If the error exceeds 10%, you
should recalibrate the battery using the optional stand alone battery
charger.
• Percent Charged—the predicted charge capacity of each battery
in percent.
• Battery Status—For Battery 1 and Battery 2, Present or Missing
tells you whether a battery is installed.
Built-In Battery Gauge
Each Lithium Ion battery has a five-segment LCD gauge that displays
its charge status. Each segment represents 20% of the charge capacity.
The gauge is active unless the battery is in shutdown mode. You can
view the gauge with the door open.
