Re: Verizon FIOS Battery Backup

said by JackBauer:

Disagree on your mathematics comment.

I seriously was considering Freedom Essentials because its call quality would be superior to DV as it is not VOIP.

When we were switched over from FiOS Freedom Essentials to DV, there was no change in quality but we certainly got more features w/ DV. Also, our monthly tax on phone service went down by ~$4.50 being offset by an increase of ~$1.00 for DV over FE. If you have FiOS, you can't get anything but DV when you change from an older package (at least that's what I've been told).

In response to NOYB's comment about V* being responsible for maintaining phone service through a power failure, IIRC, V* never guaranteed phone service, even with Copper/POTS. However, I feel that the BBU is V's equipment and it should be their responsibility to maintain all parts of it, including the battery. But that subject has been beaten to death here and it is in the TOS that the battery is the customer's resp after the 1-year warranty expires.

It used to be that if your FiOS TV remote went belly up, you'd call them and they'd send a new one free of charge (I've done it twice, in the distant past) - no more (unless you get a sympathetic CSR). Now, you have to purchase replacement remotes as well.

As an aside, I've often wondered if you could get a full-sized sealed vehicle battery (such as an OPTIMA AGM type), substitute it for the 7 AH battery in the BBU and get much longer than 8 hours of backup. I'm not talking about plugging it into the auxiliary battery port on the BBU (if one exists on your particular unit) but rather extending the normal connections for the internal battery. I'm just not sure if the charging circuitry in the BBU would handle the larger battery.

Ive wondered about the auxillary port on the BBU as well. Ive never seen a unit plugged into that thing, does something exist for it?

Back to the FioS DV Vs. FiOS POTS /regulated... in some states, Verizon may be mandated to supply a certain amount of battery backup. I dont think FiOS can circumvent that if its NOT FiOS Digital Voice.

I'm not talking about the aux port as I think that it does NOT provide a charging voltage to a battery connected to it. I was talking about disconnecting the internal battery and reconnecting its leads to a larger, external one.

The Blue Top OPTIMA, D34M battery has a 55 AH rating (should give over 60 hours of backup), is sealed and I've been running a pair in my boat for over 6 years and one in my car for over 5. I keep the boat batteries on a smart charger over the Winter put-up season and they have been very reliable. I had them tested this past fall and they passed fine but are probably nearing the end of their service life.

There was a discussion about using the BBU aux port, a little while ago, and someone (birdfeeder? Polo Dude?) linked to a post about using it but I can't find it right now.

Which smart charger do you use?

I have done some performance tests using a larger battery connected as you said. A new 35AH battery replaced the good condition 7AH battery. My BBU is hacked to provide phone/data/video during a power outage. (I would have no fortitude to simulate a power outage otherwise. What? no internet until tomorrow? The natives would get very restless. )

7AH runs at least 6 hours. 35AH runs 18. There's a circuit which monitors battery drain which shuts off ONT before battery is depleted. I believe that circuit is designed for a 7AH battery which may be why the 35AH only goes to 18 hours instead of 30 like I'd expect.

Ordinarily, when the internal battery level is low enough to shut down the ONT, one could then press the blue Emergency Use button which runs the ONT until the battery hits 10V. For a rechargeable depleting that low causes damage and while it will charge again and maintain, that battery now has a shorter life. The ReplaceBattery sensor will kick in sooner.

My suggestion, based on numerous tests on my BBU, is to maintain the 7AH internal battery for its 6-8 hour life, and be prepared to manually connect your higher capacity battery off the Auxiliary Battery port. I have not yet completed that performance test. Day job interferes lately.

Jack, I never answered your question way back when. I use a NOCO Genius G750 smart charger to hold a battery charge in readiness. »www.amazon.com/NOCO-G750-Automat···04LX3AS6

The BBU charge circuit appears adequate to charge my 35AH battery under test, except it takes a long time and did trigger a ReplaceBattery condition. I pulled the power plug from the wall for a two-minute outage, then plugged back in to resume charging.

There is no capability of pulling power out of the Auxiliary port. It is strictly for power input. I haven't found the right size barrel connector. Actually, I did once but I can't find it again. It was the exact size for ID and OD but was part of a different voltage-rated wall wart. I found it while looking for something else, so I set it aside. Kicking myself for not pulling it out.

Original post »FiOS BBU operation [long post]

Someone recently said to disconnect the signal return between BBU and ONT, but that ended up shutting everything down after 15 minutes. Maybe that works on a different BBU, just not on mine.

This works for me. »Verizon Online FiOS FAQ »Can I keep data and TV service active during battery operation?

It's a Guest (by Marinco) 2614A, marine dual battery charger designed to be installed in the engine space on an inboard boat (must be ignition protected). It is a 3-stage charger that looks at the battery state and applies full rated output (10A or 5A depending on which battery bank it's outputs are connected to) until the battery voltage reaches an "almost charged" set point, then it goes into "Absorption" mode which lowers the current to about 60% of the full load value until the battery reaches what is considered fully charged state and then it drops the charge current back to 0-3A to maintain a float level on the battery, depending on what the battery voltage is doing.

Its designed to not "cook" the batteries once they attain full charge.

Thanks - was just curious because I bought an Xtreme Charge about a month ago and it saved two batteries a Ctek 7002 could not. I was amazed.

Darn thing needs to be fixed though, has a problem with the LEDs and it's kinda annoying I have to send it back to be repaired after only having it a month, but again... It saved me from replacing a car battery on a car that come off lease relatively soon. A great investment to save sulphated batteries. Love that thing.
