Is a motorcycle battery 12 V or 6 V?
Most of the motorcycle batteries are the conventional 'lead-acid' batteries. These batteries can be either of 6 volts or 12 volts. If the batteries are in good condition, then the actual value of voltages isn't these values. When the battery is charged fully, and it's at peak, the terminal voltage of each cell is 2.1V. via
