    176  * Note that bat rail cannot be measured until board power is turned off for one second or more. When power is off, we monitor the bat voltage every 9 hours. When the board is fully powered on and booted into Linux, the bat reading cannot be continually updated and reports the last read voltage when the board was powered off.

     245== Battery Voltage Reading ==
     246The battery voltage rail (bat) cannot be measured until board power is turned off for two seconds or more. When power is off, the GSC monitors the battery voltage every 18 hours. When the board is fully powered on and booted into Linux, the battery voltage reading will be the last read voltage when the board was powered off. For always on applications where battery voltage needs to be accurate, it is suggested to have the GSC do a powercycle for two seconds at a convenient time to get an updated battery voltage reading.
