Battery Swap Time
3.3.3 Battery Swap Time
Assuming the default power saving parameters and battery reserve level have not
been altered, battery swap time is between 10 and 15 minutes—you will not lose
data if the battery is replaced within this time frame.
Keep in mind that user data is stored in a RAM-based folder by default—data in
these RAM folders is lost if the main and backup batteries are completely drained,
or if the unit is cold reset. The safest place to store data is in the \Storage (onboard
FFS) folder or on an SD or MMC memory card.
To protect against data loss, the unit will automatically shut down with enough
reserve in the main battery to last up to 72 hours.
3.3.4 Charging The Battery
Batteries shipped from the factory are charged to approximately 40% of capacity.
They must be fully charged prior to use.
Keep in mind also that, along with the main battery, the WORKABOUT PRO is
equipped with an internal, backup battery that preserves data stored on the unit
while the main battery is swapped.
Important: The backup battery is trickle charged from the main battery. To
maximize battery life, avoid excessive discharging and recharging
of the backup battery by keeping the main battery fully charged.
IF YOU ARE POWERING UP A NEW UNIT, a warning message
may appear on the screen indicating that the backup battery
capacity is low. To recharge the backup battery, you must fully
charge the WORKABOUT PRO with the main battery installed in
the unit. An overnight charge is recommended.

3.3.4.1 Chargers And Docking Stations

Important: FOR DETAILED INFORMATION about chargers and docking
stations, refer to Chapter 9: Peripheral Devices & Accessories

For battery safety, refer to “Lithium Ion Battery Safety Precau-
tions” beginning on page280.
Lithium Ion battery packs must be charged before use. These batteries can be
charged with a variety of chargers and docking stations. These include:
Desktop Docking Station (Model #WA4002-1)—operates as both a charger
and a docking station. Operating as a charger, both the battery installed in
the hand-held and a spare battery can be charged simultaneously.
