What are the effects of disconnecting the negative terminal of a car battery?

[EleanorFitz]

Disconnecting the negative terminal of a car battery will cut off all power to the vehicle, making it unable to start. Below is an introduction to car batteries: 1. Introduction: A car battery, also known as a storage battery, is a type of battery that works by converting chemical energy into electrical energy. 2. Classification: Car batteries are divided into conventional lead-acid batteries, dry-charged batteries, and maintenance-free batteries. Typically, when people refer to a car battery, they mean a lead-acid battery. The normal service life of a car battery ranges from 1 to 8 years, depending largely on the condition of the vehicle. 3. Principle: It uses lead plates filled with sponge lead as the negative electrode, lead plates 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.
