Power Supply
The LXE MX5X uses two batteries for operation.
A replaceable Lithium-Ion (Li-Ion) 2800mAh battery pack. The battery pack recharges while in
the MX5X with the computer in a powered cradle or with the optional external power source
attached. The main battery pack can be removed from the MX5X and inserted in the MX5 Multi-
Charger which simultaneously charges up to six battery packs in four hours.
An internal 450 mAh Nickel Metal Hydride (NiMH) coin cell backup battery. The backup battery
is recharged directly by an external power source. Full charging of the backup battery will take
seven hours. The backup battery must be replaced by qualified service personnel.
Connecting the MX5X to an external power source, and a main battery in the MX5X, is necessary
for backup battery charging.
