About the battery
Note
The device uses a rechargeable Lithium-ion smart battery. Internal circuitry enables the
battery to report its condition to the device. The device displays the battery status via the
LED power indicator, icons on the screen, and status messages appearing in the Device
Status area of the display. Battery information may be collected using the service tool.
New batteries are shipped from the manufacturer with a 30 percent charge to extend
shelf life. When installing a new battery in the device, you must plug the device into AC
power to wake up the battery. If the AC power is not applied to the device, the new
battery will appear discharged.
The Device Status area displays a low-battery status message when 30 minutes of
power remain and again when 5 minutes remain.
Battery charging is provided by the device's internal power supply.
For a complete list of battery specifications, see the device's directions for use.
Best practices
The following practices help to extend the life of the battery and the device.
• Whenever possible, keep the monitor plugged in to charge the battery.
• Remove the battery when storing the device for an extended amount of time.
• Replace batteries that trigger a low battery status message when fully charged.
• Do not use damaged or leaking batteries.
• Store batteries with a 30 to 50 percent charge.
• Store batteries within the temperature range indicated for each period:
The battery in the wall system provides backup power during a power
outage, not power for normal use. Except during cleaning and maintenance
activities, the wall system should remain connected to AC power at all
times.
WARNING Safety risk. When handling and storing Lithium batteries: Avoid
mechanical or electrical abuse. Batteries may explode or cause burns, if
disassembled, crushed or exposed to fire or high temperatures. Do not
short or install with incorrect polarity.
