Does the Corolla battery have radiation?

[JamesFitz]

Corolla batteries do not emit radiation. Types of batteries: They can be categorized into acid batteries and alkaline batteries based on the electrolyte. Based on electrode materials, they can be divided into lead-acid batteries, iron-nickel batteries, and cadmium-nickel batteries. Currently, lead-acid batteries dominate the market, with electrodes primarily made of lead and the electrolyte being a dilute sulfuric acid solution. Functions of the battery: When starting the engine, it provides a strong starting current (around 10A) to the starter. When the generator is overloaded, it assists in supplying power to electrical devices. During engine idle, it powers electrical devices. The battery also acts as a large capacitor, protecting the vehicle's electrical appliances. When the generator's terminal voltage exceeds the electromotive force of the lead-acid battery, it converts part of the electrical energy into chemical energy for storage, i.e., charging.
