🔍 Key Concepts

• Behavior of nickel-cadmium batteries during normal charge • Purpose of gassing in Ni-Cd batteries versus overheating or overcharging • How charging current is usually adjusted based on battery condition

💭 Think About

• Is gassing always a sign of danger in nickel-cadmium batteries, or can it be normal at a certain stage of charge? • If the battery is on a normal charge and is gassing freely, what does that suggest about whether the current is too high, too low, or appropriate? • Which option would be consistent with a controlled, routine charging process rather than an emergency response?

✅ Before You Answer

• Confirm what “normal charge” means for Ni-Cd batteries (not equalizing, not rapid charge). • Recall whether free gassing during normal charge is expected behavior or a sign of trouble for Ni-Cd chemistry. • Check which action would best maintain battery health without risking overheat or undercharge.
