🔍 Key Concepts

• Typical nominal cell voltages for common battery chemistries (lead-acid vs. nickel-cadmium, etc.) • The difference between one cell and a battery made of multiple cells in series • Standard voltages used on small boats and vehicles (e.g., 6 V, 12 V systems) and how they are constructed from cells

💭 Think About

• Which of the answer choices look more like complete battery assemblies rather than a single cell? • Think about a standard 12-volt lead-acid car or boat battery: about how many cells does it usually contain, and what does that tell you about the voltage per cell? • Which voltage value is more commonly associated with another battery chemistry (like nickel-cadmium) rather than lead-acid?

✅ Before You Answer

• Be sure you are focusing on one cell only, not the whole battery pack. • Recall that a common 12-volt lead-acid battery is made up of multiple identical cells in series – verify how many. • Double-check that the value you pick is a single-cell nominal voltage, not a system or multi-cell voltage like 6 V or 12 V.
