Battery specifications 3 cell (Integrated Wall
System)
9 cell (Vital Signs Monitor)
Rating 10.8V 1.9 Ah (20 Wh) 11.1V 6000mAh (66Wh)

Charge time to 100% capacity Always plugged in 4 hr
Patient exams per charge
1 N/A 47
Age to 70% capacity
2 N/A 300
Operating time per charge for continuous
monitoring
3, 4
N/A 2 hr (only if clinician remains in the
room)
1
A patient exam includes NIBP, Temperature, and SpO2 measurements at the rate of one patient every 10 minutes with
a 2-minute display time out setting and a new battery.
2
After this many full charge and discharge cycles, the battery has aged to where its total capacity has been reduced to
70% of its rating.
3
This specification is based on a monitor with the following characteristics:
• A new, fully charged 9-cell battery
• CO2, SpO2, SpHb and the radio operating continuously
• One blood pressure measurement every 10 minutes
• One printout every 10 minutes
As batteries age, their capacity diminishes. Replace the battery when a noticeable decrease in operating time is
observed or when total capacity is below 70% (as described in Note 2 above).
4
If battery power supplied to the monitor falls below the specified lower limit, the monitor powers down. There is no
impact on monitor performance or accuracy as the battery charge runs down. A high-priority alarm occurs when a charge
of 5 minutes or less remains on the battery. Plugging the monitor into a power outlet starts recharging the battery
immediately and prevents the monitor from powering down.
