How to Use Test Results to Extend Battery Life

Proactively preventing Cell wear requires accurate interpretation of diagnostics and the application of meticulously tailored, data-informed mitigation strategies. One major strategy is observing the State of Charge (SOC) and ensuring it is sustained between 20 to 80% to avoid overcharging/ deep discharging which quickly accelerates wear on cells. In addition, thermal management also plays a critical role: users can mitigate excessively high operational temperatures which for most batteries lie between 20℃ to 30℃, by acting on the temperature diagnostic data streams.

Further still, trends in internal resistance can inform usage and charging behaviors that can lower strain on the battery. An example is the reduction of fast charging which slow down the chemical processes that are likely to damage the battery’s components over a long period. The user’s ability to act is further enhanced with the predictive diagnostics powered by sophisticated algorithms and machine learning that identify potential heightened risks for capacity fade. Appropriate actions can therefore be taken pre-emptively before significant performance loss occurs. Strategic maintenance informed by diagnostics significantly optimizes operational dependability and reliability while greatly enhancing battery life.
