Is a Voltage of 12.5 Normal After Starting the Car?

Car battery voltage is 12.5. Below is an introduction to battery voltage: Car battery voltage is typically 12V or 24V. Generally, household gasoline-engine cars use a 12V battery, while diesel engines, which operate differently from gasoline engines, require higher voltage and thus often use a 24V battery. Under normal circumstances, the battery voltage before starting the car ranges between 11.8V and 12.8V, and after starting, it should be between 13.2V and 14.8V. As long as the voltage during startup is not lower than 11V, it is considered normal. Car Battery: Also known as a storage battery, it is a type of battery that works by converting chemical energy into electrical energy. Typically, the term 'battery' refers to a lead-acid battery, which is mainly composed of lead and its oxides, with a sulfuric acid solution as the electrolyte. Lifespan of a Car Battery: The normal lifespan ranges from 1 to 8 years, depending largely on the vehicle's condition. If the vehicle's alternator charges normally and there are no electrical leaks or grounding issues, the battery can generally last more than 3 years. If you notice that the battery isn't holding a charge, the starter is weak, or the headlights are significantly dimmer, the battery should be removed and charged for 12-24 hours using a charger. If this doesn't help and the mileage exceeds 50,000 km, and the alternator is functioning properly, further action may be needed.
