Introduction
One of the major advantages of Nickel-Cadmium batteries is their ability to maintain low and stable internal resistance over thousands of cycles. Here’s why.
Why Ni-Cd Internal Resistance Remains Stable
1. Robust Electrochemical Structure
Ni-Cd batteries use highly conductive electrode materials that resist degradation.
2. Excellent High-Current Capability
Low resistance design supports heavy discharge without overheating.
3. Superior Temperature Tolerance
Resistance remains stable even in extreme cold or heat, unlike lead-acid batteries.
4. Lower Electrolyte Degradation
Alkaline electrolyte has a long life and does not easily form insulating layers.
Industries That Benefit Most
- Railway & metro systems
- Aviation power (APU & emergency systems)
- Telecom & communication towers
- Mining machinery
- Power plants and substations
Conclusion
Ni-Cd batteries remain a preferred solution in demanding industrial applications because their internal resistance stays low and stable across a long operational lifespan—ensuring consistent power delivery and reliability.
