What is the lifespan of MANPADS battery systems?

The lifespan of MANPADS (Man-Portable Air-Defense Systems) battery systems is typically around 25 years. This longevity is due to the advanced technology and materials used in the batteries of these systems, which are designed for prolonged storage and reliability under various operational conditions. Over time, however, battery performance may decline, and maintenance or replacement might be necessary to ensure the effectiveness of the system. Understanding the lifespan of these components is critical for military or defense personnel to maintain readiness and ensure that the systems are operational when needed.
