What is the maximum lifespan of a dry battery?

[EdwardMarie]

Dry batteries can last up to 3 to 4 years. Introduction to car batteries: Car batteries, also known as storage batteries, are a type of battery. Their working principle involves converting chemical energy into electrical energy. Typically, what people refer to as a car battery is a lead-acid battery, which is mainly composed of lead and its oxides, with a sulfuric acid solution as the electrolyte. Lifespan of car batteries: The normal lifespan ranges from 1 to 8 years, largely depending on the vehicle's condition. If the vehicle's alternator charges normally and there are no electrical leaks or grounding issues, the battery can generally last more than 3 years. If you notice that the battery is not holding a charge, the starter is weak, or the headlights are significantly dimmer, the battery should be removed and charged for 12-24 hours using a charger. If the problem persists and the vehicle's mileage exceeds 50,000 kilometers, and the alternator is functioning properly, it may be time to consider replacing the battery.
