Hi @sjjt0410,


The NBN backup battery allows you to make phone calls during a power outage using a corded phone, for up to five hours.


The alarm in your power supply and battery backup unit will beep if the battery is running low on power and needs replacing. The beeping sounds becomes more frequent as the battery drops down to a critically low level.
