Re: FiOS BBU operation [long post] I still say the easiest solution is just to plug the BBU power supply into a UPS. I get 16 to 18 hours of runtime on mine before the ONT BBU will switch to it's own internal battery. So in almost five years of having FiOS, my ONT BBU has never needed to use it's internal battery since I've never had a power outage last long enough to exhaust the battery of the UPS that my ONT BBU is plugged into.(in over 18 years here I've never had an outage near long) |

The internal losses when on battery, even with NO amps being drawn from the outlets, will kill most consumer UPS batteries long before 16-18 hours. My 1500 VA unit only runs about 4 hours with a very light 25 watt load on it. |

How big is your UPS? |

My 1500 VA unit only runs about 4 hours with a very light 25 watt load on it. My ONT BBU is connected to an APC 1500(Back-UPS XS) with the extended runtime battery. The extended runtime battery is the same size as the main unit but is sealed. It is all battery unlike the main unit which has a small battery in it. Without the extended runtime battery I would only get a few hours of run time.
I use around a dozen of these types of units around my condo to get between 1.5 hours and 18 hours of runtime from my electronic devices. Depending on the load on each UPS. The UPS for my ONT and the UPS for my alarm system has the smallest loads so I can get up to 18 hours of run time from both of those. While something like my main unRAID setup (with 22 hard drives and six enclosures) only gets 1.5 hours of runtime. The newer APC units I've purchased recently are the APC Back-UPS Pro 1500 units with the extended runtime battery. They don't make the XS units any more.

| Would be nice to be able to plug one of these directly into the ONT BBU's aux power input, eliminating the external UPS (and its inefficiencies) completely.
If APC (or a competitor) ever took one of these and fitted it with the proper style connector so we didn't have to butcher the cable and fabricate our own, they'd probably sell a few. |
