Terminal voltage for a fully charged 12-volt battery is typically in which range?

Explanation:
For a 12-volt lead-acid battery, the terminal voltage when fully charged and at rest is about 12.6 to 12.7 volts. Each cell in the six-cell pack is roughly 2.1 volts, so six cells give about 12.6 volts when fully charged. Under load the voltage drops, and while charging it can rise above this resting value, but the typical resting fully charged reading is 12.6–12.7 V. The other ranges correspond to partially discharged states or charging, not a fully rested, fully charged battery.
