Charge a battery pack

The battery pack is being charged when the Rugged Industrial PC is connected to any 
of the specified power sources. The Rugged Industrial PC can charge the battery pack 
while in use. While the battery is charging, the red LED on the front is lit.

The first time, or after a long time in storage, the Rugged Industrial PC takes up to 12 
hours to be fully charged. Normaly the battery is charged in 6 hours.

Note!

A new battery may require up to five charging cycles until it reaches full 
capacity. 

Conserve battery power

An easy method to prolong battery life is to lower the screen brightness. To adjust the 
brightness use the function buttons described in the chapter  ”Function buttons” on 
page 5.

Bridge battery

The Rugged Industrial PC is equipped with a bridge battery, which is located inside 
the Rugged Industrial PC. The purpose of the bridge battery is to supply power when 
the battery pack is replaced and provide power to some components when the Field 
Tabled PC is turned off.

Note!

The bridge battery is designed for short-term use only.

The bridge battery is charged when the AC power source is connected. It is also 
charged with power from the battery pack.
