UNIT 4: Battery Failure Mechanisms

The lesson will start by examining the natural aging processes, which occurs even when the battery is operated under ideal conditions, and why batteries designed for specific applications are often specified with a different life expectancy than others. Unfortunately, batteries are seldom operated under ideal environmental and operational conditions and the impact that this has on battery life will be examined in detail. While many of those conditions are an inherent part of the application where the battery is being operated, this lesson will also provide the student with a guide to the measures that can be taken to minimize that impact.
