What is the difference between a start-stop battery and a regular battery?
2 Answers
Here is an introduction to the differences between a start-stop battery and a regular battery: 1. Usage frequency: Start-stop batteries designed for cars have more usage cycles and a longer lifespan than regular batteries. Their plates are harder than those of regular batteries, and the active material is less prone to falling off, making them suitable for cars with start-stop mode. 2. Battery capacity: Start-stop batteries have a larger capacity and can charge and discharge quickly. Ordinary lead-acid batteries cannot discharge large currents multiple times in a short period, and their separators do not allow ions to pass through quickly. 3. Battery lifespan: Cars with start-stop systems are equipped with 'start-stop dedicated batteries' and 'start-stop dedicated starters' as standard, with a lifespan 3-8 times that of regular batteries and starters. Under normal use, the battery lifespan can exceed 6 times that of a regular battery.
The start-stop battery and the regular battery are quite different, as I noticed when I drove my new car last year. The start-stop battery is designed to be more durable, as it needs to handle frequent engine starts and stops, requiring much higher current. Each start-stop cycle involves rapid charging and discharging. My current car uses a start-stop battery, and during summer traffic jams, the system automatically shuts off and restarts the engine without any hesitation, making it incredibly smooth. However, a regular battery can't handle this workload. It might work fine in older cars, but if used for start-stop functions, it won't last long—prone to early failure or complete breakdown. There's also the lifespan issue. Start-stop batteries often use AGM technology, making them more durable. Mine lasted three years before needing replacement, while regular batteries typically require inspection every two years. If they experience deep discharge, they might fail even sooner. When I replaced my battery, the technician mentioned that while start-stop batteries are more expensive, they save hassle and money in the long run. Don’t mix them up—installing a regular battery in a start-stop car not only results in slower starts but could also damage the alternator circuit, leading to extra repair costs.
