What is the normal voltage range for a car battery?
1 Answers
The normal voltage range for a car battery is between 11.8V and 12.8V. A car battery, also known as a storage battery, is a type of battery that works by converting chemical energy into electrical energy. Typically, the term 'car battery' refers to a lead-acid battery, which is mainly composed of lead and its oxides, with a sulfuric acid solution as the electrolyte. The car battery is a crucial component of a vehicle, supplying power to the engine ignition system and other electrical equipment when the engine starts or operates at low speeds. When the engine runs at high speeds, the alternator generates sufficient electricity, and the onboard charger automatically stores excess electrical energy in the car battery.
