Genuine FiOS OEM Approved Replacement Battery (3 Year Warranty) by GS Battery - GT12080-HG - Premium Replacement for PX12072-HG

Good price and worked perfectly. Took a couple of minutes to install and everything works fine.

I got this to replace the original battery (which was also manufactured by GS Battery) in our interior FiOS optical network terminal, which finally gave up after 6 (yes, 6!) years of service, including several prolonged power losses. The battery arrived pretty fast, the packaging was good enough (small cardboard box - no padding but the interior fit was good enough to prevent battery from moving around), both terminals were protected by clear plastic "covers" and there was a sticker on the battery with the date it was charged (mine had the date from previous month of this year). I removed the plastic "covers" from battery terminals, connected it in a place of old battery and so far it seems to be charging and discharging without any issues. Overall I'm pretty happy with this model and its price. Yea, you can buy a similar, "generic" (branded with some obscure names) batteries for about $10 less, but they only have 1 year warranty which is useless anyway (the return shipping will not be cheap and Amazon won't actually accept these "hazardous materials" devices) and which basically means you will have to throw these less expensive batteries away after about a year or so (if you have frequent power outages). So if you are looking for similar battery for your ONT - look no further, in the end you will actually be saving money compared to more "generic" models, even if it'll last at least half as long as the original OEM battery lasted in my ONT.

This is my second time ordering this battery for my Verizon FIOS service. The first battery lasted just under 5 1/2 years which is great. Battery arrived and had just been manufactured about 2 months prior. Excellent instructions and easy swap out.

I also purchased this as a replacement for my VERIZON FIOS battery backup. I'm also not feeling right that I should have to replace the battery, but it implies to me that I now own the on-site equipment that it's installed in, so that's a fair trade, maybe. The standard battery that failed last week was six (6) years old and from the same source. The original battery was 7.2Ah and this replacement is 8Ah, so it may provide a slightly longer backup in the event of a power outage. I purchased this, in spite of the price being double that of a standard 12V battery, because I felt if it lasts for six more years it would have saved me the difference in hassle. And the warranty is three (3) years, so your risk is in that 3-6 period. It's unfortunate that the FIOS unit can't be silenced when the battery is low or removed, even with the button for that. I suppose they sell a lot more batteries that way, but next time I'll unplug the unit and see what no longer works. If it's just the land-line phone, well, that means I won't want a land-line phone after that. We're all headed that way, anyway. What I'm saying is this is the last FIOS battery I plan to buy. The swap is simple and Verizon has a video on-line to explain it. The Verizon price for the battery was very close to the price here, but my experience with Amazon Fulfillment is much better than my experience with Verizon customer "service". So, I'd buy it here even if the price was different.

We had a 30+ power outage several months ago due to an ice storm. When the power came back on and our Fios box started beeping and indicating that there was a battery issue. I unplugged the unit and the beeping went away. But the beeping returned several weeks later. I went through the process several times but figured that it was a lost cause. So I ordered this new battery and now there is silence. Shipped fast, packed well and about $10 cheaper than the local battery store.

So, my FIOS control box in my garage - where the FIOs comes into my house - starts going BEEP every once in a while. Being a bit lazy I let it go for a couple of days and then it starts getting irritating and I go look to see what is going on with the box. There are little LED lights on the box and now instead of a green light I have a red light. Labeled next to it says I need to replace the battery. I go on line to my FIOS account and see there that the battery inside is out of warranty and that I need to buy a replacement from FIOS for a lot of money and replace the old battery. Then I go online and find there are many different brands out there that are selling these batteries here on Amazon as well as other places. After reading the reviews, I decide to not go for the super cheap ones and instead get one of the same brand and specs that FIOS sells for more money. I go ahead and get this one that is identical to the ones FIOS sells as their official replacement from Amazon at a good savings. It arrives and it takes me all of 10 minutes to figure out how to remove the old battery install this one, and Bob's your Uncle I now have a green light on my FIOS box in my garage and everything is great again. I took my old battery over to Best Buy and they happily took it to recycle so the lead and acid are not going into a landfill and messing up the environment. As I have had this in my system now for just a few weeks so far I cannot comment on how long it is going to last, but it is quality made and the specs are actually slightly better than what I had in there originally so I expect it will last even longer.

Bell MTS in Manitoba uses this UPS box for powering up the fibre internet box. It gave me warning of low battery for months and no one could help me until I found this battery being sold on Amazon. I tried ordering few times from other sellers and they kept cancelling the order. I am glad this seller actually followed through the order and I received the battery in perfect condition. It was easy to replace the old battery and happy to see that the alarm beeping is gone
