Can a Peugeot 408 be fitted with a non-start-stop battery?

Peugeot 408 can be fitted with a non-start-stop battery. Additional information: The differences between start-stop batteries and regular batteries are as follows: 1. Different service life: 1.1 The lifespan of a start-stop battery can reach 6 years. Dedicated start-stop batteries for vehicles can endure more charge cycles and last longer, typically 3-8 times longer than regular batteries. The plates in start-stop batteries are harder than regular ones, preventing active material from easily detaching, making them suitable for vehicles with start-stop systems. 1.2 Regular batteries have a service life of about 2 years. 2. Different battery capacity: 2.1 Start-stop batteries have larger capacity and can charge/discharge rapidly. Conventional lead-acid batteries cannot handle multiple high-current discharges in short periods, as their separators don't allow rapid ion passage. 2.2 Regular batteries cannot handle multiple high-current discharges in short periods, as their separators don't allow rapid ion passage. 3. Different prices: 3.1 Start-stop batteries are more expensive. They use stamping technology with higher technical requirements, and the increased production costs raise the overall price. 3.2 Regular batteries are cheaper.
I've actually had similar confusion. After driving a Peugeot 408 for over two years, I found the start-stop function saves fuel well but causes frequent battery issues. While non-start-stop batteries can theoretically be installed, it's not recommended in practice. Peugeot's start-stop system requires high-endurance batteries like AGM or EFB that can handle thousands of charge-discharge cycles - ordinary lead-acid batteries lack this capability. After installation, the start-stop may immediately fail, warning lights may illuminate on the dashboard, and battery lifespan could shrink from 3-5 years to just 1-2 years. Worse, voltage instability might affect the vehicle's computer or lighting systems, potentially requiring hundreds of dollars to reset the ECU module if not handled properly. I recommend sticking to OEM-spec batteries - saving a little money might lead to much higher repair costs. When replacing, check the original battery model and have it done at a professional shop, unlike my previous experience of messing around only to switch back.
