Bought mine at the corner “Radio Shack” after the local grocery store was out of them in stock. first one in 1 1/2 years of service. (don’t know that I needed a new one but thought it was about time.)
It is hard to find the CR2450N batteries, funny that Minn Kota does not sell them to their dealers. We have a few of them here and if we sell out we have more coming tomorrow.
