Can Cars with Auto Start-Stop Function Use Ordinary Batteries?
3 Answers
Cars equipped with an auto start-stop function cannot use ordinary batteries; vehicles with this feature should use AGM batteries. Here are the characteristics of AGM batteries: 1. Higher cyclic charging capability compared to ordinary batteries, resulting in a longer service life. 2. Greater electrical capacity stability throughout the entire service life. 3. More reliable low-temperature performance. 4. Reduced risk of accidents and environmental pollution. 5. Simple maintenance and minimized deep discharge. Note: If it is necessary to use an ordinary battery under specific circumstances, the auto start-stop function can be disabled by reprogramming the vehicle's computer at a 4S dealership, eliminating the need for manual deactivation.
I've been driving a car with auto start-stop function, and my friend from the car factory told me that regular batteries really can't handle the frequent start-stop cycles. Regular batteries have shallow discharge depth and are prone to over-discharge, damaging the internal lead plates. After multiple start-stops, their performance drops sharply, and the start-stop function stops working within a few days. Dedicated AGM batteries are designed with high cycle capability and excellent heat resistance. Although they cost 200-500 RMB more, they can last 4-6 years, making them much more cost-effective in the long run. I once tried to save money by installing a regular battery, but within a month, the engine had trouble starting, and the repair costs ended up being much higher. I recommend that new car owners who can afford it should go straight for AGM batteries to avoid being stranded on the road and affecting their travel plans.
As a car enthusiast with some technical knowledge, I've analyzed this issue. The auto start-stop system requires an enormous instantaneous current, which ordinary batteries' chemical structure can't handle due to frequent deep cycling - this leads to plate sulfation and unstable voltage. AGM batteries feature superior sealing, high vibration resistance, and stable voltage output, making them ideal for start-stop vehicles. Using a regular replacement not only disables the start-stop function but may also blow fuses or damage circuits during high engine loads, resulting in costly repairs. For daily driving, regularly checking battery voltage helps detect early warning signs. Don't risk saving a few bucks on this critical component.
