Batteries tested: Milwaukee 2 AH vs 12 AH, Dewalt and Makita. Battery performance compared in impact driver (low current), hammer drill (low/medium current), reciprocating saw (high current), and air blower (very high current). Battery size had a huge impact on tool performance, including torque and total run time. In some instances, larger tool batteries actually hurt tool performance. I buy all the products tested to ensure unbiased test results.
