Did they adjust the number of holes they advertise on a single battery? I have the 6" and I could have sworn when I bought it before last season, they advertised 100 holes through 16" of ice. I see now they claim 65.
I love the auger, never ran out a battery but tried last weekend to run it down some, mostly to see if my blades were getting dull and affecting battery life. I drilled 30 holes and had one bar left on the battery, but we were over 16" of ice in most spots I drilled. So that might be in line with the 65 claim, but nowhere close to the 100 they claimed when I bought it.
