Dear razimmer41, 

We understand that you are looking for battery backup modem from Arris.

Could you please let us know the model number of the modem so it will be easy to assist you further.

 

 

Thank you!  All I see is BGW 3210-500

Does that info help?Any ideas about a battery backup?

You could just pickup a decent UPS (backup power supply) to run it. Probably cheaper than a proprietary battery setup. I did it on mine and I think it was like 50$ and I run my modem/router/server off it for unstable power in my area.
