Battery Usage and Storage Conditions

The life expectancy of your battery should be several years, provided that it was

purchased from an approved source.
Your battery goes through a calibration procedure when it is first installed or replaced.

This procedure can take up to 72 hours to complete and is repeated every six months.
If your battery becomes fully drained during a power outage, the calibration procedure

will need to be repeated.
Your battery should be installed in your Telephony Modem and kept there at all times.

Do not store the battery separately from the Telephony Modem for any prolonged
period of time.

Battery Disposal Guidelines

To ensure compliance with current and future rechargeable battery take-back laws, ARRIS
has joined Call2Recycle, a collection program for rechargeable batteries throughout North
America. US and Canadian customers should visit
recycle your lithium-ion battery backup units (BBUs).

Getting Battery Status

To assess whether the battery needs to be replaced, the Telephony Modem charges,
discharges, and recharges the battery pack as part of a battery test. The Telephony Modem
re-tests the battery periodically afterwards, usually every 180 days. The Battery LED and the
Registration Status screen indicate the status of the battery.
To view the Registration Status screen:
1. Using a web browser, access http://192.168.100.1/ You may have to manually adjust
your computer's IP address to (for example) 192.168.100.6 to access the HSD pages.
2. Click the CM State link below the ARRIS banner.
3. Scroll down, if necessary, to see the Power Supply Telemetry and Battery Test State
information at the bottom of the page. The expected states are:
•
