Batteries Tested: DeWALT PowerStack, DeWALT 2.0 AH, DeWALT 5.0 AH. Battery performance compared using an impact driver, hammer drill, reciprocating saw, and air blower. Cold temperature performance is tested after batteries are chilled to below freezing temperature for over 12 hours. Batteries also tested for amp hour capacity. Finally, the PowerStack battery is dismantled to look at the build construction. My goal is to always provide accurate and honest test results by avoiding outside pressure from manufacturers. To do this, I always buy all of the products that I test along with the test equipment and supplies used for the testing.
