I bought an APC 1400 back in the summer of 2014. Worked fine but the last power outage before I replaced the UPS battery my cable modem and router lasted about 20 minutes. It was fine for short outages but not few hours one. I installed a new Lead Gel battery in October of 2022. Now it lasts over 3 hours.
But whatever keep the coax up offsite the battery dies so the out cable modem goes down. What I do if my wife other people are online I make my smartphone a wifi hotspot and goes through the cellular network instead. I only tried it when only a few neighborhoods were affected. If we have huge power outage we may get cell calls and SMS only. > On Jan 5, 2023, at 13:22, Keith Lofstrom <[email protected]> wrote: > > I have an ancient Tripplite 700VA UPS, which is briefly > triggered maybe twice a year, and needs a new sealed lead > acid (SLA) battery maybe every two years.
