The DeWalt DCBP518H2-XJ 18V XR 5.0Ah Powerstack Battery Twin Pack is the next dimension in power to come from DeWALT Power Tools. Their innovative design features an all-new, class-leading battery technology that is capable of taking your working productivity to the next level across all your existing DeWALT 18V XR Power Tools. Wanting increased 18V power tool power? Are you working in tight spaces but needing 18V performance? DeWALT Powerstack has got you covered. Features The stacked pouch cell battery technology provides a low impedance construction meaning that the rate of flow of electrons is much higher thanks to the innovative internal pouch battery connectors and electrodes providing a greater surface area vs a traditional cylindrical battery cell type. A low impedance construction translates into much higher max watts out, providing more power to your power tools and unlocking the 18V power tool potential to new heights - increasing the application speed significantly. Stacked pouch cell batteries also benefit from superior thermal performance vs cylindrical batteries. This ultimately increases battery durability, improves the cycle life and results in a much greater return on investment for your kit. 50% more power, 50% more work per charge, 2x lifespan and a unique rubber overmold as a complete battery pack vs a DEWALT DCB184 XR Battery Pack.
