The following chart is an approximation. Actual battery capacity will vary based
on usage, ambient temperature and peripherals drawing power from the MX5:
100% capacity 2800 mAh minimum
80% capacity 2240 mAh minimum
Deciding when to put a fully charged Main Battery pack in the MX5 is difficult to
quantify because it is very application specific. 1000 mAh may be the cutoff for
one customer who uses the computer frequently, while 500 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.
How To . . . . Insert Main Battery
The Battery Compartment is located at the bottom of the back of the computer.
The fasteners in the main battery Pack are connected to the Battery Pack. Press
the Power key after the battery is inserted into the MX5.
Note: On first use the battery pack should be charged with an external power
source (i.e. AC Adapter) – 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 LXE Multi-
Charger.
Note: Using the battery removal tool (or a coin) twist each fastener to the left
to loosen the battery pack. Twist the fastener to the right to tighten the
battery pack.
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 MX5 to conserve the
main battery and charge the backup battery.
