Batteries
Overview
General
A complete battery management system provides maximum battery performance.
Depending on usage, the run time per battery for new, fully-charged batteries is up to
3.5 hours. Monitoring NBP, CO
2
and SpO
2
drains battery power faster than other
parameters. The display brightness, graphing, and connection to a wireless network
can also alter battery run times.
Audible and visual alarms alert you when loss of power is imminent and on-screen
capacity gauges indicate battery charge condition and capacity. A “
BATTERY LOW ”
message at the top of the screen warns you prior to complete loss of battery power.
You should replace the battery or connect the monitor to an AC power source when
the message is displayed.
Lithium-Ion Technology
The batteries used in this monitor are rechargeable batteries containing lithium-ion
cells. Each battery contains an integrated electronic fuel gauge and a safety protection
circuit. The following are the key points you should know about lithium-ion battery
technology:
„ The battery will discharge on its own, even when it is not installed in a monitor.
This discharge is the result of the lithium-ion cells and the bias current required
for the integrated electronics.
„
By the nature of lithium-ion cells, the battery will self-discharge. The self-
discharge rate doubles for every 10°C (18°F) rise in temperature.
„ The capacity loss of the battery degrades significantly at higher temperatures.
