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 MX5 is always 'on' even when in the
Suspend state and draws battery power at all times. Tap the Windows icon | Settings | System |
Handheld | Battery Info 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 MX5:
100% capacity 2800 mAh minimum
80% capacity 2240 mAh minimum
Deciding when to put a fully charged Main Battery pack in the MX5 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 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 Main Battery pack before that point.
