I don’t understand why this battery, which is a backup and therefore never really gets used, lasted only 10 or 11 months. While the $20 price tag is attractive, because the battery life is so short, I’m not sure it is a good value.

Great Price!

This is my 2nd purchase. Last one lasted around 2 years. Fast delivery. Good price.
Ronald A. Pellecchia II –
Exactly what was needed for the Verizon back up battery. Easy to install. Battery life is unknown since it’s new. That’s why 3 stars
Peter Rye –
This is not the normal battery that you find in the store, but its what you need for your FiOS gateway.Easy to buy and easy to install. Perfect replacement.
Mark Gutknecht –
Our Verizon box has the back up battery for our home phone. Yeah, I’m one of those hold outs who still has a home phone. When the box starts beeping, I know to replace the battery. I can’t say I’ve tested the batteries life when the power goes out as our phones are wireless. I do have a corded phone for an emergency but haven’t had to use it in many many years. So ultimately, this is a big beep stopper I guess! The beeping occurs every three years or so I think. Shipping was quick and installation was very easy. Exact fit.
Caroline Gaynor –
This battery only lasted 7 months. I will not repurchase.
MonitorAvenger –
My only dislike is Verizon. Their FIOS product beeps mercilessly when the battery winds down, and will not work if you take it out. The replacement battery I ordered stopped the beeping! This is a great product at a discount price that solved my issue.

The battery fit and was easy to install!

Battery failed after 8 months. Used as backup in Verizon Fios installation. Other batteries, although more expenive are better values.

This was a replacement for a similar battery purchased several years ago. Using as a power source for a sonar on my boat. Works as advertised and maintains it’s charge better than most I’ve tried similar to this one. Highly recommended.

I first used the Might Max when my upper battery was reporting problems in my Verizon/Frontier FiOS ONT backup box. Swapped it out and no problem (been a year so far), so when the bottom OEM battery failed, I went right back to the Mighty Max and problem is again solved. If you are getting the replace battery idiot light on your battery backup for your FiOS setup, this is the one to get and it is literally a 2 minute install. THere is just a snap on cover and 2 battery connectors. Could not be easier.

Needed this to refurbish an older car jumper box. This 8ah battery replaced a long dead 7ah battery so was an upgrade. This battery did not have the same terminals as the original but I knew that when I made the purchase. I figured that a small modification could make things fit and it did. Battery seems to be working as it should in the jumper box. Only time will tell how long it will last.

Worked great for my VIOS box. Vios wanted 49.99 and other suppliers were lower but this is the best price I found. Easy to install and I can not rate the battery life yet. Ask me again in 5 years…lol.

Appears to be similar to Verizon battery, but half the cost. Same size as battery to be replaced and easy to install. Won’t know about battery life until it needs to be replaced.

Five stars is for replacing a battery received as new, but was too old to be considered a fresh battery.Customer service at the Mighty Max vendor read the date code and determined a replacement was in order.The battery was everything it needed to be. Many thanks for great customer service.

This accomplished its intended mission by ending that irritating beep from my Verizon back-up unit in the basement (which I don’t really need since I don’t have a landline, but there was some uncertainty as to whether it would affect my internet line). Now the question will be how long will this box last before I need another one?
William Tan –
This does not fit the compartment of the old battery in the FiOS box, it is slightly too large. My FiOS battery backup is White with blue buttons.

Elizabeth Kornbluth –
Had a hard time figuring out why there was an intermediate beeping in the basement, after discovering the sound was a warning of low battery life in the Verizon box, I looked to purchase a replacement from Verizon. After seeing the price they posted for a new battery back up, I had to look around for a more reasonable solution. Mightymax was HALF the cost and has the same specs as the Verizon battery. Why throw away money when you can buy the same thing for less? The battery works perfectly and solved my problem. Never hesitate to save money when the products are the same. Oh and the shipping was much faster than the estimated shipping stated, double win!

So far so good. Haven’t had it for long, but a heck of a lot less than what Frontier offered us. The only reason we even bought a new battery was to get the warning beep shut off,so didn’t want to spend $50. Glad it was very easy to check compatibility. Happy with it so far.

This is the third MightyMax battery I’ve purchased to replace my original Fios battery. First one lasted about 18 months – that’s fine. But the most recent one was just over ten months – which is not good for a never used backup. Will give it one more try – but if it last less than one year, will try an alternative.

I used this as a replacement battery for my FIOS telephone and it lasted 19-months, which is longer than the warranty but less than an unused standby battery should last (in my opinion). If it was one=half the cost of the GS brand, it would be acceptable since it lasts one-half as long.
