Works perfect in my modem.
I was surprised to find out that Comcast no longer provides a backup battery in their cable/phone modems. Found this one on Amazon and ordered it. I installed it in the modem and it reached full charge in a short time. The settings screen says I now have over 400 minutes backup time for my phone if the household power were to fail. Would purchase again if needed.

Internet connection is compatible with Mediacom , but VOIP is not.
The modem worked fine but the VOIP feature did not work with Mediacom, which was not listed as a service this equipment was incompatible with.

Exactly What We Needed
When the power goes out, your phone can still be used. Very important to keep your phone service on if you need it.

Good to go
This product worked in my Comcast technicolor cable modem. It was competitively priced and arrived on time. I am very happy.

Is what it says it is!
It works, was a good price (much cheaper than Comcast) and easy to install. Now when the power drops out the connection does not have to reset.
