About the Internal UPS Battery
The computer contains an internal UPS battery that is automatically charged when you
place the computer in a powered smart dock. The UPS battery can power the computer
for approximately 30 minutes at -20 °C (-4 °F) or higher. The UPS battery allows you to
continue using the computer when it is not mounted in a dock or when the vehicle bat-
tery is being changed.
If the UPS battery becomes critically low on power, the computer performs a controlled
shutdown. You can recharge it by placing the CV41 into the smart dock. You can fully
charge a discharged UPS battery in approximately 4 hours.
Caution: Disconnect the UPS battery if you plan on shipping
