Second battery?


Second battery?

The Arris eMTA that Comcast installed has a place for a second battery. We live in a area where there are long power outages in winter so is it possible to install a second battery and does  Comcast install it or can it be purchased elsewhere and I install it?

Re: Second battery?

Hi Phil,

At this time, Comcast provides only one battery with the eMTA. While you may be able to find backup batteries for sale online, we would discourage you from making any changes that could potentially damage the modem. As with all of our leased equipment, only Comcast employees or agents should make any repairs or modifications.

Thanks for the question!

Have you considered connecting the Modem to a UPS?
