Cadmium-nickel (NiCd) batteries are widely used in various applications due to their robustness and reliability. Proper electrolyte maintenance is critical to ensuring their optimal performance and longevity.
1. Monitor Electrolyte Levels Regularly
- Inspect the electrolyte levels periodically to ensure they are within the recommended range.
- Use distilled or deionized water to replenish the electrolyte if levels drop due to evaporation. Avoid using tap water, as impurities can degrade the battery’s performance.
2. Check Electrolyte Concentration
- Measure the electrolyte’s specific gravity using a hydrometer to confirm it meets the manufacturer’s specifications.
- If adjustments are necessary, consult the battery manual for the correct potassium hydroxide (KOH) concentration.
3. Avoid Contamination
- Ensure all tools and containers used for handling the electrolyte are clean and free of impurities.
- Wear protective equipment to prevent contamination and ensure safety during maintenance.
4. Temperature Management
- Electrolyte performance can be affected by temperature fluctuations.
- Maintain the battery environment within the recommended temperature range, typically 20–25°C (68–77°F), to prevent excessive evaporation or freezing.
Regular maintenance of NiCd battery electrolytes ensures their reliability, prevents capacity loss, and extends their operational life.
