The Battery
The Omnii is powered by a Lithium-ion Smart Battery pack, 5000 mAh—Model ST3001.
Battery packs shipped from the factory are charged to approximately 40% and must be fully charged prior
to use. Batteries can be charged using a variety of chargers and docking stations. For detailed information,
see “Battery Details” on page 21.
Replacing the Battery Pack
Figure 2.6 Omnii Battery
Assuming the default power saving parameters and battery reserve level have not been altered, a battery
can be removed for up to 4 minutes without losing data. After 4 minutes the terminal may reboot.
Removing the Battery Pack

Press the two buttons at the sides of the compartment simultaneously, and slide the battery out.
Installing the Battery Pack
•
Slide the charged battery with the contoured plastic facing you into the unit with the contacts match-
ing position and the guide tabs moving into the corresponding slots at the base of the compartment.
Click both sides of the battery into place.

If your computer is equipped with a hand strap, re-attach the clip to the slot at the base of the battery.

frame.
