E-EQ-MX3CERG-A-ARC MX3-CE Reference Guide
Chapter 3 Power Supply
Introduction
The MX3-CE computer is designed to work with a Lithium-Ion (Li-Ion) battery pack from LXE.
The LXE MX3-CE 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-CE is
connected to external power using the power jack. There is a 50 mAh Nickel-Cadmium (NiCd)
Backup Battery inside the MX3-CE that is recharged only by the Main Battery Pack.
The MX3-CE 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-CE 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 and eight hours when the MX3-CE is connected to external power
through it's power jack.
Handling Batteries Safely
Never dispose of a battery in a fire. This may cause an explosion.
Do not replace individual cells in a battery pack.
Do not attempt to pry open the battery pack shell.
Be careful when handling any battery. If a battery is broken or shows signs of leakage do not
attempt to charge it. Dispose of it using proper procedures.
Caution
Nickel-based cells contain a chemical solution which burns skin, eyes, etc. Leakage
from cells is the only possible way for such exposure to occur. In this event, rinse the
affected area thoroughly with water. If the solution contacts the eyes, get immediate
medical attention.
Caution
NiCd and Li-Ion batteries are capable of delivering high currents when accidentally
shorted. Accidental shorting can occur when contact is made with jewelry, metal
surfaces, conductive tools, etc., making the objects very hot. Never place a battery in a
pocket or case with keys, coins, or other metal objects.
