1 DAY AFTER RETURN PERIOD , THE BACK-UP WENT DEAD AND SHUT DOWN THE ROUTER-MODEM! Today I plugged it in and it seems to work fine. An APC that you cannot trust is worse then worse-less. POST SCRIPT: MARCH 17, 2017. After working with the manufacturer on some simple APC testing, they determined that the battery back-up unit unit was defective and shipped a replacement unit with pre-paid postage to return the defective unit to them. While still an irritation, they did make the unit good.
