I have fios for tv and internet. NO phone. I just received a tv message that my CyberPower/Verizon M1136a UPS battery needs to be replaced for *phone* backup. It does not mention the two services I do have. Is the UPS not needed/used for tv and internet (the only services I do have) when I don't have fios phone. (I already have the modem/router plugged into a different ups.) What happens with internet and tv if there is a power failure if the fios backup unit does not protect the system unit?
