Why does the car battery suddenly run out of power?

[LeEmilia]

Car batteries may suddenly run out of power due to depletion of battery charge, insufficient battery electrolyte, or internal battery failure causing damage. Generally, the lifespan of a car battery is around 3 to 4 years, which is related to the user's driving habits and the road conditions the vehicle is driven on. Relevant information about car batteries is as follows: 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. Typically, what people refer to as a battery is a lead-acid battery. This is a type of battery mainly made of lead and its oxides, with a sulfuric acid solution as the electrolyte. 2. Working principle: It uses lead plates filled with spongy 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.
