5.1 What is Dynamic Z-Track™ (IT-DZT)?

Dynamic Z-Track™ (IT-DZT) is an extension to Impedance Track™ (IT) used to accurately gauge battery conditions under variable load conditions. IT-DZT provides reliable performance and improved battery longevity for applications with fluctuating load currents such as but not limited to power tools, drones, and Intel® Turbo Boost Technology. This section serves as an overview of the IT-DZT algorithm as an extension of IT.
