Do I need to replace my HH3000 back up battery?

[mickdave]

When the red light on the 3000 hub is red, indicating low battery, is it compulsory to replace the battery. I have no need for battery power.

No it is not. The modem will fully function without the battery.

That’s correct! But remember that to maintain phone service (including 911) during a power outage, you need an uninterrupted power supply (UPS) to power your Home Hub 3000.

Please advise - is it safe to leave the dead battery in the modem or is it ok to remove it and not replace it.

Always remove batteries when not in use, as over time they can start corroding and cause issues. Just remove, discard properly, and not replace it unless you need the battery backup.
