To determine the state of charge of a wet cell nickel-cadmium battery, what should be done?

🔍 Key Concepts

• Differences between lead-acid and nickel-cadmium (Ni-Cd) wet cell batteries • How specific gravity of the electrolyte behaves in Ni-Cd vs lead-acid batteries • What information voltage readings (no-load vs under load) can give about state of charge

💭 Think About

• Ask yourself: For which battery type is a hydrometer (specific gravity reading) a reliable indicator of state of charge? Does that also apply to Ni-Cd? • Consider whether the electrolyte specific gravity in a Ni-Cd battery changes much with state of charge, or stays almost constant. • Think about which test better reflects a battery’s ability to deliver power in real conditions: checking voltage with no load, or checking voltage while the battery is supplying a normal load.

✅ Before You Answer

• Verify whether Ni-Cd electrolyte specific gravity significantly changes with charge state. • Confirm which methods listed are commonly associated with lead-acid batteries, not Ni-Cd batteries. • Check which voltage test (no-load vs under nominal load) is typically used to assess a battery’s performance and true state of charge.
