Batteries

Note:
The MX3 computer is designed to work with a Lithium-Ion (Li-ion) battery from LXE. Under
normal conditions it should last approximately eight to ten hours before requiring a recharge. The
more you use the scanner or the RF transmitter, the shorter the time required between battery
recharges. The MX3 keeps date and time valid for a minimum of four days using a fully charged
Backup Battery and a Main Battery that has reached the Low Warning point.

Main Battery

The main battery has a rugged plastic enclosure that is designed to withstand the ordinary rigors
of an industrial environment. Exercise care when transporting the battery making sure it does not
come in contact with excessive heat or any power source other than an LXE MultiCharger or
MX3 unit.

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. Use the following chart to determine when to replace the battery:
Deciding when to replace a Main Battery pack in the MX3 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 300 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.

Backup Battery

The internal Nickel Cadmium (NiCd) backup battery provides power to the unit for a short
amount of time when the main battery has been depleted, removed or has failed. The backup
battery requires no user intervention. Replacement is performed by LXE.

Battery Hot-Swapping

Note:
When the battery power level is low, the MX3 will signal the operator with a continuous, one-
second beep. Beeping will continue until the battery is replaced or the battery completely depletes.
You can replace the main battery without shutting the unit off. Simply replace the discharged
battery with a fully-charged battery. The backup battery will retain data during a main battery hot-
swap for at least five minutes.
