Query: Ten minutes is not enough

We used 10 minutes cut couple six inch cuts and where done for six hours while charging batteries.**** TOOK THIS BACK **** Got the 10" Remmington 1.4 HP Electric pole saw it WORKS GREAT. Used up ladder, ground work and took off pole cut two stumps ground level. Used 5 hours cut stacked pick up load of wood. Did sharpen once about middle of day two pass on each tooth with file, great improvement.
