Can a Start-Stop Car Use a Regular Battery?

[Cole]

Batteries with automatic start-stop functionality can be replaced with regular ones, but it is not recommended because regular batteries do not have the same powerful features as the original ones, and some functions cannot be achieved with regular batteries. Many car owners consider automatic start-stop to be a redundant feature, but it requires a more expensive specialized battery—the AGM battery. This is a valve-regulated sealed lead-acid battery with glass fiber separators, which is significantly more expensive than regular batteries. Many car owners find the replacement cost painful and consider switching to regular batteries. However, the start-stop system's battery requires a high charging current, and during braking, there is also kinetic energy recovery, which results in even higher instantaneous currents. Installing a regular battery can easily lead to damage. AGM batteries have the following characteristics: 1. Higher cyclic charging capability compared to regular batteries, resulting in a longer lifespan. 2. Greater capacity stability throughout the entire lifecycle. 3. More reliable low-temperature performance. 4. Reduced risk of accidents and environmental pollution. 5. Simple maintenance and reduced deep discharge.
