What is the voltage of 6 volt discharged battery?

A discharged 6-volt battery typically has a voltage significantly lower than its rated 6 volts, often around 4.8 to 5.0 volts or even lower, depending on the extent of the discharge. If the battery is fully discharged, the voltage might drop below 4 volts, indicating that it needs recharging or replacement. It's important to check the specific battery type, as the voltage can vary based on its chemistry and state of charge.
