MX6 PPC User’s Guide E-EQ-MX6PCOGWW-C-ARC
Backup Battery
The MX6 PPC has a rechargeable lithium battery installed to maintain time, date and setup
information. It is charged off the main battery. The lithium battery is not user serviceable and
should last five years with normal use before it requires replacement.
Note: This battery should only be changed by authorized service personnel.
CAUTION
This product contains a lithium battery. There is a danger of explosion if
battery is incorrectly replaced. Replace only with the same or equivalent
type recommended by the manufacturer. Dispose of used batteries
according to the battery manufacturer's instructions.
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. This is important to remember -- the MX6 PPC is always 'on' even when
in the Suspend state and draws battery power at all times. Tap Start | Settings | System | Power
tab to check the battery status and power reading.
The following chart is an approximation. Actual battery capacity will vary based on usage,
ambient temperature and peripherals drawing power from the MX6 PPC:
100% capacity 2000 mAh minimum
80% capacity 1600 mAh minimum
Deciding when to put a fully charged battery in the MX6 PPC is difficult to quantify because it is
very application specific. 1600 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 battery before that point.
