1.1 BATTERY 
  Main Battery 
The 9400 Mobile Computer is powered by a rechargeable 3.7 V/1800 mAh Li-ion 
battery pack, and it takes approximately 4 hours to fully charge it. However, the 
charging time may vary by working condition. During normal operation, the 
mobile computer can work for up to 10 hours. 
  Backup Battery 
The backup battery on the main board takes charge when the main battery is 
removed or drained out. When fully charged, the 3.7 V/70 mAh rechargeable 
Lithium button cell helps retain data in SRAM and maintain the system running in 
suspend mode for at least 20 hours without the main battery. In the meantime, 
you have to replace the main battery as soon as possible.
