Can a Regular Battery Be Used to Replace the One in a Vehicle with Auto Start-Stop?
2 Answers
For vehicles equipped with an auto start-stop function, it is not recommended to replace the battery with a regular one. The specific reasons are as follows: 1. Using a regular battery may lead to insufficient working current for the starter: When a vehicle has an auto start-stop function, the starter requires a larger working current during operation. A regular battery cannot support such a high current, so only an auto start-stop battery capable of delivering a higher current output should be used. Due to the higher cost of such batteries, many car owners opt for regular batteries to save money during replacement. However, this practice can damage the starter. 2. Impact on power management: If a regular battery is installed in a vehicle with an auto start-stop function, it may cause abnormal power management. For example, some car owners who switch to regular batteries and disable the auto start-stop function still experience issues such as the battery not charging fully, mismatched power management systems, or the car failing to start. 3. Health risks for passengers: Auto start-stop batteries have relatively weaker heat resistance, so they are usually placed in the trunk or inside the cabin to avoid exposure to high temperatures from the engine. If a regular battery is installed, it may produce acid mist and other harmful gases during charging and discharging, posing health risks to passengers.
I've driven a car with auto start-stop for several years and replaced the battery myself. Now I really don't recommend switching to a regular battery. Regular batteries are designed for general use and can't withstand the frequent charging and discharging during repeated starts, making them prone to overheating or short circuits. At best, they might last a few months before failing, affecting the proper functioning of the auto start-stop system. Imagine how frustrating it would be if the car automatically shuts off and then can't restart on the road. After switching to a dedicated AGM battery, I've noticed much more stability, with the lifespan at least doubling. Although the cost is higher, it's worth it in the long run. Remember to check the vehicle manual before replacing to avoid being scammed; choose a dedicated model that matches the voltage, and have it professionally installed by a technician for peace of mind.
