Q

How much is the nominal open-circuit voltage of one cell of a fully charged lead-acid battery?

🔍 Key Concepts

• Typical cell voltage for a single lead-acid cell • Difference between a cell and a battery (multiple cells in series) • Common nominal voltages of full lead-acid batteries used on small vessels (e.g., 6 V, 12 V)

💭 Think About

• Which of the choices look like complete battery voltages rather than the voltage of just one cell? • If a 12-volt lead-acid battery is made up of several identical cells in series, what is the approximate voltage of each cell? • How many cells are usually inside a 6 V or 12 V lead-acid battery, and what does that tell you about the voltage of one cell?

✅ Before You Answer

• Be clear on the difference between a cell (single electrochemical unit) and a battery (group of cells). • Check how many cells are in a typical 12 V lead-acid battery and divide the total voltage by the number of cells. • Eliminate answer choices that are clearly whole battery voltages, not single-cell voltages.
