I kept loosing internet connection, sporadically, on my U-verse TV and Internet during the past several months. After 4 lost connections in one day, decided to order this Mighty Max to replace the original battery. Have only had it a few weeks, but so far so good. No lost connections.

Fits the AT&T Belkin backup unit nicely. Half the price of the Belkin brand battery.Working well so far; easy to connect; just wish they had instructions on how long to charge this battery before inserting into Belkin shell and connecting to AT&T modem.

This was a direct replacement for my AT&T phone battery backup. Fit in the backup case and charged in about 12 hours. Works as expected

Not the exact head as the original, but at half the price I can’t complain.

The first battery lasted approximately 5 years. My computer guy installed it +/- 4 months ago and so far so good. The product was well packed and arrived on time.
Denise Garbero –
Exactly what we needed. Thank you.

Forget wasting time with AT&T support when your Uverse backup battery dies. This was half the price of ordering from Belkin and it was easy to install and is working perfectly.When I called AT&T, I spent over half an hour speaking with two agents neither of whom stated that AT&T no longer provides replacement batteries. The second guy just gave me a phone number to call. It was the number for for Arris who in turn gave me the number for Belkin. After a Google search, I discovered my best bet was ordering from ; not AT&T, not Arris and not Belkin. Thanks Mighty Max Battery for providing the solution I needed at a great price.

Exact replacement, low cost, fast and free shipping. As this is a backup power battery, only time will tell for longevity and value.

Works just as well as the one I got with the original unit and it was a fraction of the cost.

Easy to install. Works like a charm in my UVerse Belkin unit.

Worked as described.

Less than half the price from Belkin and fast free shipping. I was hesitant to order because the terminals were F1. The original battery had F2 terminals which are a little wider but the wider connectors on the wires still grip the battery very snugly.
