Zeno 5, Operation
Long-term battery storage is not recommended. If storage is necessary:
• Always try to use a 'first-in first-out' approach to minimise storage time.
• Lithium-Ion batteries age much faster at elevated temperatures. Store batteries
at temperatures between 0° C and 20° C.
• Always charge batteries to at least 40 to 60% before storing them. An over-
discharge phenomenon damages the batteries. An over-discharge phenomenon
occurs when an empty battery is stored for a long time such that the cell voltage
drops below a lower limit.
• To minimise storage degradation, recharge stored batteries to 40 to 60% every
four or six months to prevent over-damage.
• A never used Lithium-Ion battery that has been stored for three years may have
limited or no useful life remaining once put into service.
To maximise the runtime of your batteries, consider:
• The display backlight is a large drain on the battery. Try to keep its brightness
as low as possible.
• Tap Start⇒Settings⇒Power to display a screen that provides detailed
information about the battery status of the battery installed in the Zeno 5.
• When the Zeno 5 is switched off, it goes into a low-power, suspend state but
continues to draw a small amount of power from the battery.
Do not leave the Zeno 5 in suspend state for more than a week.
For long-term storage, remove the battery from the Zeno 5.
