LabSat 4 is shipped with a rechargeable, lithium-ion Smart battery pack (Inspired Energy NB2037HD34). It is UN38.3 (transportation) certified and CE, FCC and REACH/RoHS compliant. 

The battery pack will power LabSat 4 for at least 1 hour of operating time. When LabSat 4 is powered externally, it will charge the internal battery pack (if fitted in LabSat 4), and seamlessly switch to battery operation when external power is removed.

If LabSat 4 is switched off while connected to an external supply, it will continue to charge the battery until it reaches full capacity. Charging in progress is indicated by the blue CHG LED under the power port on the rear panel. When the charging stops, the blue LED will turn off.

When LabSat 4 is operating from battery power, you can see the charge status of the battery in the top-right section of the display.

If you are using external power and the battery is being charged, you will see a power symbol over the battery symbol.

The discharge temperature range for the battery is - 20 °C to + 60 °C.
If LabSat 4 is operating from battery power and the temperature falls outside of this range, the unit will power down. 

The charge temperature range of the battery pack is 0 to + 45°C. 
If the temperature falls outside this temperature range, LabSat 4 will stop the charging of the internal battery but will continue to operate from the external power supply. 

If the internal temperature exceeds the maximum operating temperature LabSat 4 will display a warning on the screen.
