Mighty Max Battery ML8-12 – 12V 8AH Replacement, Very easy to install.

Beep, beep, beep, beep, beep, beep, beep, beep, beep, beep, beep, beep, beep, beep, beep, beep, beep. No more beepwhat more is there to say?. My verizon fios box battery was on it’s last leg, beeping every 24 hours, and after months of daily pressing the ‘override’ button, i had enough. But when i contacted verizon to purchase a new one, i almost choked at the price. As usual, i turned to amazon. Com to see what was offered at a more reasonable price. I decided on this battery after reading reviews. The battery arrived in good condition, i read the instructions, switched out the battery, and viola. It really was very easy to do. The hardest part was getting the verizon fios box open. It has only been a few days, but for now, i am very pleased with the purchase and should have ordered it months agoif anything changes, i will update this review.

It works great, but i’ve only had it for a month. If it stops working at any time, i’ll update the review. I bought this instead of fios’ $50 replacement battery. This was a great price ($18. 49) with no shipping charges. I ordered it on saturday and received it on wednesday. Oops, maybe i’m leaving too much of a seller review here. It shall be knownupdate: the red ‘replace battery’ light is lit on the fios bbu. This battery didn’t even last four months.

After listening to the beeping every 24 hours for over a year i decided to check amazon for an alternative to the $35 price verizon wanted for a battery. Decided on this one after reading the reviews. It arrived very quickly and was a perfect fit for the original. ‘replace battery’ light went out and no more beeping.

My motorcycle batteries last 2 years—period. Even with a good trickle charger. I have tried several brands. 5 years at best and replace it the 1st time it doesn’t start. Usually while it is still in my garage. At this price—i will replace them as soon as they show their age. I have now used this brand for 2 bikes and am very happy with the quality.

This did the job of quieting my verizon fios battery backup, which was squawking every 24 hours or more often for a fresh battery. Much more reasonably priced than buying directly from fios. It’s only been in for a few weeks, though, so verdict is still out on how long it lasts. 5 months after install*** battery beeping is back and i’ll have to replace this battery. It’s within 1 yr warranty, but warranty info is not available online and fighting with the manufacturer will cost me more in time and sanity (beeping in the background) than new battery. Will buy another and will hunt out warranty information at the beginning so that when new one goes down within year, i’m ready for the battle.

The hardest thing about this battery change was figuring out how to open the verizon wall box. But the battery change out is straight forward and the replacement is an exact model for the replacement. And i saved a service call of $75 plus the part.

The product was as described. Just wanted it faster than i received it. I don’t know about longevity, becausei haven’t had it that long. Hopefully it will last for at least a year. I would recommend if you need a replacement forthis type of battery.

It arrived on time, easy to install, works great, great price compared to original equipment battery.

This battery is used to replace the backup battery in our fios ‘black box’ in the basement. Everything fit, battery case, terminals, it all works. In a few years, when it’s time to replace the battery, i’ll be back.

I bought this for a verizon fios battery backup. It worked fine, for when it worked. It has a 1 year warranty, and mine lasted 1 year, and about two or three weeks. If it had died prior to the year mark, i would have rated lower; if it lasted as long as the original (3 years), i would have rated it higher. Fit is snug, just a hair bigger than the factory original battery – not a problem except to take 2 seconds more care installing.

This was a perfect replacement for a drained verizon backup battery. For the longest time i had to put with the piercing beep whenever the original battery drained. I got around by unplugging and re-plugging the terminal which seemed to quiet the thing until maybe six months later. I called verizon thinking they would give me a free replacement. The ml8-12 sells for $20 on amazon.

This is the second replacement battery i’ve bought for a really old ups. Why spend $100 for a new ups when it’s so easy and painless to replace the battery. The last one served for 3 years or so, so i’m happy.

Purchased for a fios battery back up system about a month ago. The original lasted ~ 4 years. The first replacement batter we purchased (not this brand) lasted just shy of 2 years. I’m hoping that this at least meets the original battery’s life of 4 years.

Works great to replace the battery that was in my fios/verizon ont box. The only thing is that it doesn’t have the connecting wires that plugs in from the battery to the ont box. Luckily i was able to disconnect the wires from the old battery and plug them in to this battery. It’s working great so far but i’ve only had it for about a month. Hopefully it has a long life. *update 11/16/17- beep beep beep. I got this battery back in april, so it did last about 7 months. Disappointing as i had lived in my apartment and the battery previously purchased didn’t beep for almost 3 years. Meh, you get what you pay for.
