4. Access the patient monitor’s Battery Status window to monitor the
battery’s Charge Level. See “Identify battery status using the
BATTERY STATUS menu” on page 2-38.
5. Allow the battery to discharge to less than a 90% Charge Level.
6. Re-connect the patient monitor to the AC power source and fully
charge the battery.
7. Disconnect the patient monitor from the AC power source and allow
the patient monitor to run until it displays the BATTERY LOW
message, or until the patient monitor shuts down.
8. Re-connect the patient monitor to the AC power source. Allow the
battery to fully charge to complete the conditioning cycle.
How to store the battery
Condition the battery before storing it. Conditioning the battery to
100% capacity increases the storage shelf-life of the battery.
Store the battery outside of the patient monitor at a temperature
between 20°C to 25°C (68°F to 77°F).
When the battery is stored inside a patient monitor that is
powered by an AC power source, the battery cell temperature
increases by 10°C to 15°C (18°F to 27°F) above the room’s
ambient temperature. This reduces the life of the battery.
When the battery is stored inside a patient monitor that is
continuously powered by an AC power source and is not powered
by battery on a regular basis, the life of the battery may be less
than 12 months. GE recommends that you remove the battery
and store it near the patient monitor until it is needed for
transport.
Re-condition a stored battery every six months to increase the
storage shelf-life.
How to wake up the battery
When the battery is stored for a long period of time without being
charged, it will eventually lose all of its charge and “fall asleep.” When
the battery is “asleep,” none of the LEDs on the battery will illuminate
when the battery’s on/off button is pressed. You must “wake up” the
battery before you can use it again.
There are two methods to wake up the battery:
Outside of a patient monitor by using the Cadex SMart Two+
charger.
Inside a patient monitor that is connected to an AC power source.
NOTE
The Cadex SMart Two+ charger is no longer available for purchase.
However, if your site has a Cadex SMart Two+ charger, you should
continue to use it to charge and condition the battery.
