What is the voltage of a 125cc motorcycle battery?

Electric vehicles with 5 batteries are 60 volts. The most commonly used lead-acid batteries for electric vehicles are 48 volts and 60 volts, composed of different numbers of 12-volt batteries. Below are specific precautions for electric vehicle batteries: Prevent Over-Discharge: When a battery is discharged beyond its termination voltage, continued discharge is called over-discharge. Over-discharge can severely damage the battery, significantly impairing its electrical performance and cycle life. Prevent Short Circuits: When a battery is in a short-circuit state, the short-circuit current can reach hundreds of amperes. The firmer the short-circuit contact, the greater the short-circuit current. All connection points will generate a large amount of heat, with weaker parts heating up more, potentially melting the connections and causing a short-circuit phenomenon. Prevent Explosions: Localized production of explosive gases in the battery, combined with sparks generated when connections melt, can cause the battery to explode. Avoid Short Circuits: Short circuits must be absolutely avoided in batteries. Be especially careful during installation or use. Tools should be insulated. When connecting wires, first connect all electrical components other than the battery, check for any short circuits, and finally connect the battery. Wiring should be properly insulated to prevent overlapping and pressure-induced ruptures. Precautions: When charging the battery on the vehicle, turn off the ignition lock. Do not charge the battery upside down, and try to charge it fully in one go. If you detect any unusual odors or the battery becomes excessively hot during charging, stop charging immediately and send it to the technical department for inspection. When removing the battery for charging, avoid touching the electrodes with wet hands or metal objects like keys to prevent burns.
I've been riding a 125cc motorcycle for several years, and its battery is typically 12 volts, just like regular cars. Don't underestimate its size, but the voltage requirements are quite strict. If the battery voltage drops below 12V, especially in winter, the engine may have difficulty starting or the lights may suddenly dim. I recommend buying a simple multimeter and checking the voltage every few months, keeping it around 12.6V is ideal. The battery life is generally two to three years, and it slowly discharges when not in use for long periods. I've experienced the embarrassment of push-starting when the voltage was insufficient, but later learned to charge it regularly, which avoided trouble. When parking, turning off unnecessary electrical appliances like audio systems or heaters can extend the battery's lifespan. In short, I've never seen a 120-volt motorcycle, so rest assured they're all 12 volts, just maintain them promptly.
