Modem Backup Batteries for Arris and Technicolor Gateways A backup battery slides into the battery bay of a telephony modem or gateway and keeps it powered when the electricity goes out. This collection includes replacement backup batteries for Arris and Technicolor gateways, including the Arris BPB-series packs used across the TM and TG telephony lines, each matched to specific gateway models. If your home phone service runs through your modem, this small pack is what keeps that line available in a blackout. And if it has been a few years since your gateway was installed, odds are the original battery no longer holds a charge, or your provider never included one at all, since many providers now direct voice customers to supply their own. Why Add a Backup Battery to Your Internet Setup Phone service stays up : Provider voice service is delivered through your gateway, so when the gateway loses power, the phone line goes dead. A charged backup battery keeps calls working during an outage, including 911, as long as your provider's network is up. Rides through power flickers : A momentary blip forces a modem to reboot and re-sync with the network, which can take several minutes. A battery carries the gateway straight through, so your connection never drops. Internet during short outages : A battery-backed gateway with built-in WiFi keeps laptops and phones online while the power is out, handy for finishing a work call or checking an outage map. Protects connected systems : Especially important if a medical alert system or alarm panel depends on your phone line staying live. One tip that trips people up: cordless phone base stations need wall power, so keep one corded phone in the house if outage calling matters to you. Match the Battery to Your Gateway Backup batteries are model-specific. The fastest way to identify yours is to open the battery door on your gateway and read the part number printed on the existing pack, then match it to the compatibility list on the prod
