What is the difference between a start-stop battery and a regular battery?
2 Answers
Start-stop batteries and regular batteries differ in the following aspects: 1. Lifespan: Dedicated start-stop batteries for cars have more usage cycles and a longer lifespan compared to regular batteries, with a normal service life of over 6 years, which is 3-8 times that of regular batteries. Their plates are harder than those in regular batteries, and the active material is less prone to shedding, making them suitable for vehicles with start-stop systems. Regular batteries typically have a lifespan of around 2 years. 2. Battery capacity: Start-stop batteries have a larger capacity and can charge and discharge quickly. Ordinary lead-acid batteries cannot handle multiple high-current discharges in a short time, as their separators do not allow ions to pass through quickly. 3. Price: Start-stop batteries are manufactured using stamping processes, which involve higher technical requirements and costs, leading to an overall higher price for the equipment. Once core technologies are mastered, domestically produced start-stop batteries will have significant price advantages in the future.
There's a significant difference between start-stop batteries and regular ones, primarily in their design structure. Start-stop batteries, like AGM types, use fiber to absorb acid internally, enabling them to handle the stress of frequent starts and stops without damage from the engine constantly turning on and off. Conventional lead-acid batteries lack this capability—when used in start-stop systems, they degrade quickly due to their shallow discharge depth and short cycle life. AGM batteries also charge faster, recovering power more swiftly, especially during cold starts, making ignition more reliable. Additionally, these batteries are vibration-resistant, reducing the risk of acid leakage. Overall, start-stop batteries are optimized for energy-saving systems, while regular ones may suffice in older vehicles but should not be installed in newer models without consideration—doing so risks leaving you stranded. Always check your battery type before driving; cutting corners here can lead to bigger expenses.
