Functional Description (Engineering Perspective)

The system operates by applying controlled electrical loads to the battery under test and monitoring voltage response and discharge behavior. In HRD mode, a short-duration high current load is applied to simulate real cranking conditions. The voltage drop and recovery behavior are analyzed to classify battery health.

In backup test modes, the system discharges the battery at a controlled constant wattage or current until a defined cutoff voltage is reached. The elapsed time is recorded as usable backup capacity, providing a direct measure of real-world performance rather than nominal capacity.

This dual-method approach (load testing + controlled discharge analysis) allows accurate identification of weak cells, reduced capacity, and internal degradation.
