PwrTest Battery Scenario

The PwrTest Battery Scenario is designed to facilitate automated inspection of battery and power source information.

PwrTest is capable of logging battery capacity, voltage, rate of drain, and general state for as many batteries as are in the system. Battery data is logged at a specified interval for a specified number of cycles.

Syntax

pwrtest /battery [/c:n] [/i:n] [/?] 

/c:n
Specifies the number of cycles (100 is the default) to run.

/i:n
Specifies the polling interval in milliseconds (the default is 5000).

Examples

pwrtest /battery 

pwrtest /battery /c:4 /i:1000
