Storing Batteries

• When the hand-held is switched off, it goes into a low-power, suspend state
but continues to draw a small amount of power from the battery. This
should not be an issue unless the unit is left in suspend state for more than a
week – in this case, the battery should be removed.

3.7.1 Storing Batteries

Long term battery storage is not recommended. If storage is necessary:
• Always try to use a 'first-in first-out' approach to minimize storage time.
• Lithium Ion batteries age much faster at elevated temperatures. Store batter-
ies at temperatures between 0˚ C and 20˚C.
• Always charge batteries to at least 40 to 60% before storing them. Batteries
can be damaged by an over-discharge phenomenon that occurs when an
empty battery is stored for a long period of time such that the cell voltage
drops below a lower limit.
• To minimize storage degradation, recharge stored batteries to 40 to 60%
every 4 or 6 months to prevent over-discharge damage.
• A 'never used' Li-Ion battery that has been stored for 3 years may have
limited or no useful life remaining once put into service. Think of batteries
as perishable goods.

3.8 Uploading Data In A Docking Station

Important:
The desktop docking station and quad docking station allows the WORKABOUT
PRO to link to an Ethernet network. They are typically used to upload transaction
data to a server computer when a radio link in not available.
