Insert Main Battery

Press the Power key after the battery is inserted into the MX5X.
Note:
The MX5X battery compartment is located at the bottom of the back of the mobile device. The
fasteners in the main battery pack are connected to the battery pack.
Note:
Place the battery in the battery well, making sure the tabs on the bottom of the battery pack fit into
the slots at the bottom end of the battery well. Push the battery down into the battery well while
fastening the screws. Fasten the screws tight enough to allow the rubber gasket to create a
watertight seal. If the screws do not easily twist into the threaded opening, remove the battery pack
and repeat the process. When the main battery pack is charging, the Battery Charge LED flashes
green. The backup battery is trickle-charged by the main battery. There is no backup battery
charging indicator. Whenever possible, use the AC power adapter with the MX5X to conserve the
main battery and charge the backup battery.

About Lithium-Ion Batteries

Li-Ion batteries (like all batteries) gradually lose their capacity over time (in a linear fashion) and
never just stop working. This is important to remember – the MX5X is always 'on' even when in
the Suspend state and draws power from the batteries at all times. Tap the
Panel | Power tab to check the battery status and power reading.
The following chart is an approximation. Actual battery capacity will vary based on usage,
ambient temperature and peripherals drawing power from the MX5:
Deciding when to put a fully charged main battery pack in the MX5X is difficult to quantify
because it is very application specific. 1800 mAh may be the cutoff for one customer who uses the
computer frequently, while 1000 mAh may be perfectly fine for a customer who occasionally uses
the computer. You need to determine the point at which battery life becomes unacceptable for
your business practices and replace the main battery pack before that point.

On first use the MX5X batteries should be charged with an external power source (i.e.
AC Adapter, powered MX5 cradle or MX5 Multi-Charger) – 3 hours for the main battery
and 7 hours for the backup battery. New main battery packs alone must be charged prior
to first use – this process takes up to four hours in an MX5 Multi-Charger.
