I once had a situation where our consumer electronics product was experiencing higher-than-expected return rates. Many users reported intermittent battery contact. The issue was eventually traced back to the battery springs. The manufacturer was not adequately testing the contact force of the springs in a functional setup. Their basic spring force test was insufficient. We discovered that while the spring had the correct "push-back" fuerza, its geometry was slightly off, leading to poor contact on the battery terminal. This critical detail was missed. It led to high electrical resistance. Después de esto, I insisted on a specific test. This test measured the resistance across the battery spring while it was compressed to its working height. This functional test was critical. It went beyond just spring force. This ensures both mechanical and electrical performance. This experience taught me that for battery springs, a holistic approach to QA is necessary.
