Hello @ET_Explorer That is an awesome question and I hope that I am reading it in the right sense. Customer owned devices would be supported by their manufacture, however they may be compatible to use with our services. You can check to see if the device you are interested in is listed on our approved list here: My Device Info The cost of a back-up battery to purchase with us is a one time charge of $65.00, not a reoccurring fee. If you are purchasing a battery back up from another source aside from Xfinity we would not support that device, but please make sure it is compatible with the modem/gateway that you have for your services.
