1 Answers
12V car battery's normal no-load voltage is around 13V. Here is more information about car batteries: 1. Introduction: Car battery, also known as storage battery, is a type of battery. Usually, the battery people refer to is a lead-acid battery, which is mainly made of lead and its oxides, with sulfuric acid solution as the electrolyte. 2. Working principle: It uses a lead plate filled with spongy lead as the negative electrode, a lead plate 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.
