NBN Battery Replacement Guide
How to Install Your NBN™ Battery Replacement
You will know when it’s time to replace the battery when you see a red light appear next to ‘Replace Battery’ on the nbn™ connection box. You will also hear an alarm sound – one beep every 15 minutes indicates the battery needs replacing, and four beeps every minute indicates less than half of the battery charge is remaining.
