Had the day off today so I headed out onto the ice before sunrise. I overpacked as usual and struggled dragging my sled through 4-6" of snow. After 3/4 of a mile I stopped and went to drill a hole and my auger wouldn't work. Took the battery on and off, pushed the start button on the battery, reversed the direction of the auger--nothing. It showed 4 bars of power and the auger worked 18 hours prior. I looked on-line and found a YouTube video of a guy from a baitshop saying Jiffy was having problems with their original batteries. If your battery has a dark grey start button you might want to give them a call (920.467.6167). I did and they immediately shipped me a new battery. Unfortunately I was the only one on the ice so I turned around and trudged 3/4 of mile back to the landing and packed back up. It was a perfect windless day, but now I'm working on the honey-do list.
