Battery Pack Maintenance
Observe and note the run time that a new fully-charged
battery provides for powering your product. You can
use this new battery run time as a basis to compare run
times for older batteries. The run time of your battery
will vary depending on the product’s con
fi
guration and
the applications that you run.
The battery pack gives the best performance when operated
at normal room temperature, 20 °C ±5 °C (68 °F ±9 °F).
Routinely check the charge status of the battery.
Carefully monitor a battery that is approaching the end
of its estimated life.
Consider replacing the battery with a new one if the battery
run time drops below about 80% of the original run time,
or the battery charge time increases signi
fi
cantly.
Follow the storage requirements if you store or do not use
a battery for an extended period. If you do not follow the
storage requirements, and the battery will not power the
waveform monitor when installed, consider the battery
to be damaged. Do not connect power to the waveform
monitor during this time. Remove the battery pack from
the waveform monitor. Do not attempt to recharge or reuse
the battery. Replace it with a new battery.
Battery Pack Charging
The battery pack charges automatically when the waveform
monitor is connected to the external power supply. You can
also charge the battery pack with the Tektronix WFM200BC
External Battery Charger. Remove the battery pack from the
WFM200BC charger when charging is complete.
A Lithium-Ion battery pack will self-discharge during non-use.
To achieve the longest operating time, charge your battery
pack before use. If you plan to store battery packs, read
the instructions in the
Battery Pack Storage
section of this
document.
When the battery pack is in the WFM2200 waveform monitor,
the battery gauge (
) on the waveform monitor display
indicates the approximate amount of charge.
To avoid automatic shutdown of the battery pack, only run
the waveform monitor on the battery pack when the gauge
on the waveform monitor is green or yellow.
Always verify the correct placement of the battery in the
WFM2200 waveform monitor or the WFM200BC battery
charger.
When the battery pack is installed in the waveform
monitor, it will automatically charge whenever the
supplied AC adapter is connected, whether the instrument
is On, Off, or in Standby mode.

fi
guration
Typical charging time
One fully discharged battery pack
charging in the WFM2200 waveform
monitor with the waveform monitor
turned on or off
5.5 hours
One or two fully discharged battery
packs charging in the WFM200BC
external battery charger
5.5 hours
CAUTION.
To avoid damage to the battery pack, use only
the WFM2200 waveform monitor or the WFM200BC
battery charger to charge the battery pack. Do not connect
any other voltage source to the battery pack.
NOTE.
For optimum performance, charge the battery pack
completely before using it for the
fi
rst time or after prolonged
storage.
To discharge the battery pack completely, continue to run
the waveform monitor on the battery pack until automatic
shutdown occurs. After the instrument shuts down, either
recharge the battery pack promptly or remove it from the
instrument until you are ready to recharge the battery pack.
NOTE.
To prolong the life of the battery pack and to prevent
shutdown, do not operate or charge the battery pack at high
temperatures. For best results, allow the battery pack to cool to
room temperature before using or charging the battery pack.
Do not leave a battery pack discharged for extended periods.
See the Storing Battery Packs section for information on how to
properly store a battery pack.
The battery pack stops charging under the following conditions:
The battery pack is fully charged.
The internal temperature of the battery pack exceeds the
safe charging threshold.
A fault condition occurs.
The battery pack shuts down and disconnects itself from the
WFM2200 waveform monitor under the following conditions:
The battery pack is fully discharged.
The internal temperature of the battery pack exceeds the
safe discharging threshold.
A fault condition occurs.
Battery Pack Handling
Do not disassemble, crush, drop, or puncture the battery.
Do not short the external contacts on the battery.
Do not dispose of the battery in
fi
re or water.
Do not expose the battery to temperatures above +60 °C
(+140 °F).
Seek medical advice if a battery or part of it has been
swallowed.
Do not put battery packs near heat or
fi
re. Do not put in
sunlight.
Keep the battery pack clean and dry. Clean dirty
connectors with a dry, clean cloth.
Batteries contain hazardous chemicals that can cause burns
or explode. If exposure to chemicals occurs, clean with
soap and water and get medical aid. Repair the product
before use if the battery leaks.
Do not attempt to open, modify, reform or repair a battery
pack that appears to be malfunctioning, or which has been
physically damaged.
Keep the battery away from children and animals.
Avoid exposing the battery to excessive shock or vibration.
Do not use a damaged battery or charger.
If a battery pack has leaking
fl
uids, do not touch any
fl
uids. Dispose of a leaking battery pack. See the
Battery Recycling
section for information on disposal and
recycling.
In case of eye contact with
fl
uid, do not rub eyes.
Immediately
fl
ush eyes thoroughly with water for at least
15 minutes, lifting upper and lower lids, until no evidence
of the
fl
uid remains. Seek medical attention.
Battery Pack Storage
Store battery packs in a low-humidity environment free of
corrosive gases. Storing battery packs in high-humidity
environments, or outside the temperature range, can
cause oxidation on the metallic parts, increased leakage,
signi
fi
cant aging and premature failure.
Do not store battery packs near heat or
fi
re. Do not store
in the sunlight.
Do not keep battery packs in a place where the terminals
can be shorted by metal objects (for example, coins, paper
clips, or pens).
Do not remove a battery pack from its original packaging
until required for use.
When possible remove the battery pack from the
equipment when not in use.
Charge the battery to approximately 50% of capacity at
least once every six months.
Remove the battery and store it separately from the
instrument. Refer to the
WFM2200 User Manual
for
instructions on removing and installing the battery.
For optimal battery life, store the battery at temperatures
b5 °C and +25 °C (+41 °F and +77 °F). Higher
temperatures reduce the battery storage life.
Battery Pack Replacement
Use the instructions to remove and replace battery packs.
NOTE.
Replace the Lithium-Ion battery pack only with a
WFM200BA battery pack.
See the Battery Recycling section for information on how to
properly dispose of a Lithium-Ion battery pack.
