Viewing Battery Status
You can view information about battery status in four ways:
- Two battery LEDs embedded in the E7495A/B enclosure
- Icons in the lower right of the front panel screen
- System Statistics-Battery screen, available from the System menu
- LCD gauge built into each battery
Battery LEDs
NOTE: The battery status LEDs will function only when the test set is on, in standby mode, or connected to external power.

The 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. If two batteries are installed, the second battery will have Not in Use displayed. The instrument mode you select affects the discharge rate, which determines the run time to empty. Antenna/Cable, Spectrum Analyzer, CDMA Tx Analyzer, and CDMA Over Air modes use the most power. Backhaul and Power Meter 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 condition the battery.
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.
