How Does Self-Discharge Lead to Battery Failure?
Self-discharge leads to battery failure by reducing the battery’s stored energy over time. Batteries naturally lose energy, even when not in use. This loss occurs due to internal chemical reactions.
Initially, self-discharge occurs when the battery’s active materials react with the electrolyte or other components. This reaction creates unwanted current flow, depleting stored energy. The rate of self-discharge varies by battery type. For instance, nickel-cadmium batteries have higher self-discharge rates compared to lead-acid batteries.
Next, the continuous loss of energy affects battery performance. As the charge diminishes, the battery may fail to provide sufficient power. This degradation can happen if the battery is not recharged regularly. Repeated cycles of self-discharge without recharging can ultimately lead to deep discharge. Deep discharge may cause irreversible damage to the battery’s chemistry.
Finally, as the battery loses capacity, it may no longer hold a useful charge. This situation results in premature battery failure. Regular monitoring and recharging can mitigate self-discharge. However, neglecting this can lead to the battery becoming unusable.
In conclusion, self-discharge negatively impacts battery health by depleting energy and leading to failure if not managed properly.
