Why does the auto start-stop not work after replacing the battery?

[DonovanLynn]

After replacing the battery, the auto start-stop may not work due to incorrect battery type replacement or the start-stop function not being activated. Here are the detailed explanations: Incorrect battery type replacement: Cars with auto start-stop functionality must use start-stop batteries to ensure proper operation. Therefore, when replacing the battery, it is essential to confirm the correct model. Using a regular battery will not only prevent this function from working properly but may also affect the battery's lifespan. Start-stop function not activated: The start-stop function may not be activated, causing it to fail to operate correctly. The activation method can be found in the vehicle's user manual, or you can seek professional assistance for the operation.
