Explained: What Causes Battery Self-Discharge

Key Takeaways . Self-Discharge is Inevitable in All Batteries: Self-discharge is a natural phenomenon where batteries lose their charge over time even when not in use.This occurs due to internal chemical reactions within the battery, and the rate of self-discharge varies depending on the battery type and environmental conditions.

Battery discharge time is fairly easy to calculate in principle, assuming the load draws constant current. This means the load will always draw the same amount of current as long as the battery voltage is within the range allowed by the load specifications. "Load" is a general term for eveything powered by the battery.
