When the engine is off and the alternator is not operating, the typical battery terminal voltage is about which range?

Explanation:
When the engine is off and the alternator isn’t charging, you’re measuring the battery’s resting, open-circuit voltage. A 12-volt lead-acid battery that isn’t being charged typically reads around 12 volts. In practice, a common resting range is about 12.0 to 12.2 volts, which is why that option is the best fit. The other ranges reflect charging conditions (13–14 volts) or a heavily discharged battery (around 11 volts).
