Validate and Extend Battery Life

Analyzing the current drain and conducting run-down battery tests of your designs pose several difficulties. The manual process of charging and discharging a battery is time-consuming, and it's crucial to test it at different charge levels as battery characteristics vary. Furthermore, battery parameters and charge levels must be identical when comparing test results. Achieving this is very challenging with physical batteries. Additionally, it is difficult to determine how long a device will last on a single charge, and often battery life claims do not match reality.

Keysight designed the E36731A battery emulator and profiler and BV9211B advanced battery test and emulation software to solve these challenges. This demo video guides you through the process of using the solution to verify and prolong the battery run time of your device.
