The chain saw was such a great deal $35 shipped. I could not get a chain saw that worked with my battery for anything close to that cost. I would also have to pay to ship the one I got back at my expense.
So I decided to keep my saw and modify it to work with my battery. The other battery is just longer than the new battery.
So I used my hot knife that my wife had bought me one year for Xmas.
It turned out good and now it works great with my battery. The battery is harder to get out than a normal tool.
But I don’t want to make it too easy because I don’t want it to slip out while I am using it.
