Mighty Max Battery 12V 7AH New Battery for GS PORTALAC PX12072 DG126

Perfect for the price! Works just as described. I appreciate the easy instructions for replacement that are included.

It fits and works fine. But, only lasts 7 months as opposed to the original VZ ones that lasted 3 years.

My phonesystem demands this backup battery. Verizon wanted $100 for one. I got this one, it was a drop in replacement and works just fine.

Unfortunately 3 weeks after receiving the battery started leaking acid. Quite a mess, ended up buying a battery directly from Verizon for twice the $$. You’ll get what you for if you buy a Mighty Max.

Works perfectly, no more annoying beeps from the Verizon FIOS box. Price was right too.

This battery is used in my cable box. The old one died so I wanted a replacement quickly at a reasonable price. I purchased this one online, got it within a few days, and paid about a third of what they wanted locally. It was advertised as a direct replacement for the prior battery, and it fit and worked perfectly.

Replacement back up battery for Verizon (now Frontier) system. Much cheaper and easier to get than through provider. Fit properly and very easy to install.

Was a perfect replacement for my original Verizon FIOS back-up battery and at half the cost of what Verizon wanted for their battery. As long as it has a decent life span I am very pleased.
