E-EQ-MX3RG-J-ARC MX3 Reference Guide
Chapter 3 Power Supply
Introduction
The MX3 computer is designed to work with a Lithium-Ion (Li-Ion) battery pack from LXE.
The LXE MX3 receives continuous power from two batteries. There is a Lithium-Ion Main
Battery Pack that can be recharged separately by an LXE approved battery charging unit. The
Main Battery is recharged, if required, while installed in a powered cradle or when the MX3 is
connected to external power using the power jack. There is a 50 mAh Nickel-Cadmium (NiCd)
Backup Battery inside the MX3 that is recharged only by the Main Battery Pack.
The MX3 maintains the date and time for a minimum of four days using a Main Battery that has
reached the Low Warning point and a fully charged Backup Battery. The MX3 retains data,
during a Main Battery hot swap, for at least 5 minutes.

Note: New batteries must be charged prior to use. This process takes up to four hours in an
LXE Multi-Charger or Multi-Charger Plus and eight hours when the MX3 is connected
to external power through its power jack.
Refer to the documentation received with the battery charger for complete
information.
Main Battery Pack
The main battery pack has a rugged plastic enclosure that is designed to withstand the ordinary
rigors of an industrial environment. Exercise care when transporting the battery pack making sure
it does not come in contact with excessive heat or any power source other than the LXE Multi-
Charger, Multi-Charger Plus or the MX3 unit.
When the Main Battery Pack is properly installed in the unit it provides up to eight hours of
operation depending upon operation and accessories installed. The battery pack is resistant to
impact damage and falls of up to four feet to a concrete surface.
Under normal conditions it should last approximately eight hours before requiring a recharge. The
more you use the scanner or the transmitter, the shorter the time required between battery
recharges.
