Q

Which statement is true concerning the charging of a wet cell nickel-cadmium battery?

🔍 Key Concepts

• Behavior of nickel-cadmium (Ni-Cd) electrolyte during charge and discharge • Difference between lead-acid and nickel-cadmium batteries in how state of charge is measured • Effects of trickle charging and gassing on different battery types

💭 Think About

• Compare how specific gravity changes in a lead-acid battery versus a Ni-Cd battery. Does Ni-Cd electrolyte composition change much with charge state? • Think about why manufacturers allow some batteries to be on continuous float or trickle charge. Is Ni-Cd typically damaged or tolerated by such charging? • Consider normal signs of a battery reaching full charge. For Ni-Cd, is a complete absence of gassing realistic or even desirable at the end of charge?

✅ Before You Answer

• Verify whether potassium hydroxide electrolyte in Ni-Cd batteries changes specific gravity significantly with charge state. • Check standard practice for maintenance of wet Ni-Cd cells: when is water added—before or after charging, and for what reason? • Confirm whether controlled gassing at the end of charge is normal for Ni-Cd, or whether any gassing must always be prevented.
