Introduction
Although internal resistance naturally increases with battery age, proper maintenance can slow this process and keep Ni-Cd batteries operating reliably for many years.
Ways to Reduce or Control Internal Resistance
1. Regular Full Charging
Ensures active materials remain conductive and fully restored after each cycle.
2. Avoid Deep Discharge
Recurrent deep discharge increases resistance and damages electrodes.
3. Periodic Electrolyte Check (Vented Ni-Cd)
For flooded types, maintaining electrolyte levels helps keep internal resistance low.
4. Controlled Temperature Environment
Operate Ni-Cd batteries between 15°C and 30°C for best performance.
5. Equalization Charging
Restores uniformity across cells, reducing imbalance-related resistance.
Conclusion
With proper maintenance, Ni-Cd batteries maintain impressively low resistance and long-term stability, outlasting most other industrial chemistries.
