What is the normal battery voltage for the Haval F7?

[StevenLynn]

The voltage of a fully charged battery is typically slightly above 12 volts. The Haval F7 is equipped with a maintenance-free battery. If the battery charge is insufficient, it should be promptly recharged or replaced. Principle of maintenance-free batteries: During charging, electrical energy is converted into chemical energy, and during discharging, chemical energy is converted back into electrical energy. When discharging, the metal lead acts as the negative electrode, undergoing an oxidation reaction to form lead sulfate. Lead dioxide serves as the positive electrode, undergoing a reduction reaction to also form lead sulfate. When charging with direct current, the two electrodes generate lead and lead dioxide, respectively. After removing the power source, the battery returns to its pre-discharge state, forming a chemically dynamic equilibrium. Lead-acid batteries are rechargeable and dischargeable batteries, also known as secondary batteries. Advantages of maintenance-free batteries: Due to their structural advantages, maintenance-free batteries consume very little electrolyte and generally do not require distilled water replenishment during their lifespan. They also feature resistance to vibration, high temperatures, compact size, and low self-discharge. Their service life is typically twice that of conventional batteries.
