Circular Saw Performance Test

What happens here

For the final power test, an 18V DeWalt circular saw with a somewhat dull blade is used. The creator attempts to cut across the 4x4 wood stock first with the old 18V NiCad battery. The saw clearly struggles, highlighting the inadequacy of the older battery. He then switches to the 20V MAX Lithium-Ion battery (with adapter) and makes a second cut, which is noticeably smoother, faster, and more powerful, even with the dull blade, demonstrating a dramatic improvement in performance.

Goal: Compare cutting power of the circular saw using both battery types.
