While not common in consumer electronics, iron-nickel batteries still serve critical roles in niche applications:
Primary Uses:
- Railway & Marine: Used in signaling systems and backup power due to their vibration resistance.
- Renewable Energy Storage: Reliable for off-grid solar/wind systems where longevity is crucial.
- Aerospace & Military: Preferred in satellites and remote installations due to extreme temperature tolerance.
- Industrial Backup Power: Used in factories where frequent cycling and durability are needed.
Their ability to endure harsh conditions ensures they remain in use despite newer alternatives.
