Discover Stress Testing and Internal Resistance Measurement

What happens here

To overcome the limitations of voltage-only checks, this step introduces the concept of stress testing, where a load is applied to the battery, and the resistance between its internal plates is measured. The video explains that specialized testers are available that check the resistance between the plates in the batteries. This internal resistance is a key indicator of a battery's overall health, degradation, and its ability to efficiently deliver current under demand. Such testers have been around for a while but are becoming increasingly important.

Goal: Understand the principles and importance of stress testing and measuring internal resistance for accurate battery diagnostics.
