The 112# must be a different remote then the 80# or is a new design or maybe the link remote. I have had by 80# Ultrex since June 2016 and I have changed my batteries 3 times, about once a year. The remote I have is non link, and takes standard AAA batteries. Never a days trouble out of it. I would definitely contact Minn Kota, something isn't right.
