I’ve written before about how the Federal Communications Commission’s National Broadband Map can serve as a rough guide to who provides high-speed Internet access at a particular address. Tip: A broadband-finding site from the cable industry Fios subscribers who do want to ensure their phone line stays on for a while in a blackout now have a backup option that doesn’t require buying an expensive lead-acid battery every few years: a $40 PowerReserve box that uses 12 standard D-cells to lend up to 20 hours of phone use. In late 2013, the company made the battery backup unit an extra-cost option on new installs. They will also last for a lot longer than eight hours on battery, and the wireless networks that connect them have grown far more resilient-as I realized firsthand during 40 or so hours without power after Hurricane Sandy. It’s not only that smartphones and tablets can let you keep communicating during a power outage. Verizon has since moved away from mandatory, expensive battery backup, Mitchell said: “We have seen an upswing in customers who simply do not want to deal with battery backup.” Not wanting to pay Verizon’s $39.99 list price for a replacement, I bought a $24 battery off Amazon-which did not last a year. Ours made it through four years in a cool, dry corner of the basement, and then I needed a day or two to pin down the mysterious beep we kept hearing every 15 minutes. A tech-support note says that this battery usually lasts “ between 2 and 4 years, depending on the average temperature of the environment.” To provide that reserve power, Fios boxes have long included the battery backup unit and its 12-volt lead-acid battery.
