When a nickel-cadmium battery begins gassing while connected to the battery charging circuit, what should be done?

🔍 Key Concepts

• Behavior of nickel-cadmium (Ni-Cd) batteries during normal charge vs. overcharge • Meaning of gassing in a battery and what it indicates about charge rate or condition • Correct maintenance practices for electrolyte in Ni-Cd cells

💭 Think About

• Is gassing in a Ni-Cd battery a sign of safe normal charging, or of excessive charge/voltage? • Would adding chemicals or water during active gassing make the condition safer or potentially more dangerous? • If a battery is gassing, should you increase, decrease, or maintain the current charging rate?

✅ Before You Answer

• Verify what the electrolyte in a nickel-cadmium battery actually is and whether its specific gravity is normally adjusted in service • Consider standard safety practice: when a battery shows signs of overcharge or overheating, do you typically add chemicals, add water, or adjust the charging rate? • Eliminate any option that would intensify gassing or change electrolyte composition in a way not recommended for Ni-Cd batteries

When a nickel-cadmium battery begins gassing while connected to the battery charging circuit, what should be done?

do nothing as this is a normal condition when charging

add distilled water to each cell to reduce the specific gravity of the electrolyte

add potassium hydroxide to each cell to increase the specific gravity of the electrolyte

increase the charging rate
