What is the voltage of 6 batteries?

[MacTheo]

Generally, one battery is 12V, so 6 batteries would be 72V. A lead-acid battery is a rechargeable battery that can be repeatedly charged and discharged, known as a secondary battery. Its voltage is 2V, and typically three lead-acid batteries are connected in series for use, resulting in a voltage of 6V. Functions of the battery: To supply power to the engine. When the vehicle is about to start, the battery discharges to provide electricity to the starter, which then drives the flywheel and crankshaft to start the vehicle. When the engine's power supply is insufficient or not started, it provides power to in-car electrical appliances such as the audio system and lighting system. Once the engine begins to supply power normally, the battery collects and stores electrical energy for future use. Structure of the battery: It uses lead plates filled with spongy lead as the negative electrode, lead plates filled with lead dioxide as the positive electrode, and 22-28% dilute sulfuric acid as the electrolyte. During charging, electrical energy is converted into chemical energy, and during discharging, chemical energy is converted back into electrical energy.
