Ha! Mine wants a new battery every 3 months. I disconnect and reconnect and it's happy again. For about 3 months. This is a totally useless feature that's just a pita for customers who do not have a UPS.
That's pretty much our routine.
Well if you guys ever get tired of it I would encourage you to try removing the buzzer. You'll need to unplug the power from the BBU in order to take it apart so your internet will be down, took me about 15 minutes.
1. Remove plastic covers on BBU (for the battery and the lower right wiring harness cover)
2. Remove battery
3. Unplug wiring harness from BBU (at this point power to the ONT will cut off, no more internet for now)
4. Unscrew 2 mounting screws from inside battery compartment (behind where battery was)
5. Unscrew 2 very small phillips screws that hold a small plastic cover over a thermistor also inside the battery compartment (the thermistor is wired to the circuit board and will need to be free to move)
6. Turn the whole unit around, locate and remove the two phillips screws that are recessed into the housing, holding the front panel on
7. While pressing the tab along the inside edge of the battery compartment, just above the thermistor, pull the front panel straight out. At this point the circuit board will be free of the housing.
8. Locate the small black round buzzer at the lower corner of the board, it will be labeled BZ1 on the board.
9. On the back side of the board, use a hot soldering iron to melt the two contacts. Just be careful not to melt anything else nearby! It helps to do one leg first while pulling the buzzer away from the other side with your other hand. Go back and forth until it comes free.
10. Reassemble.
11. (optional) SMASH BUZZER WITH 10 POUND SLEDGE HAMMER!!!!
It didn't seem to like not having any battery, so I put the old one in and now everything is good.
