Why does a car battery suddenly lose power?

[BentleyLynn]

Car batteries may suddenly lose power due to depletion of battery charge, insufficient electrolyte levels, internal battery malfunctions causing damage, etc. Generally, the lifespan of a vehicle battery is around 3 to 4 years, which is related to the user's driving habits and the vehicle's operating conditions. 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 primarily made of lead and its oxides, with a sulfuric acid solution as the electrolyte. 2. Working Principle: It uses lead plates filled with sponge-like lead as the negative electrode, lead plates filled with lead dioxide as the positive electrode, and a 22-28% dilute sulfuric acid solution as the electrolyte. During charging, electrical energy is converted into chemical energy, and during discharging, chemical energy is converted back into electrical energy.
