408 uses the original battery model L2-400, which is a Camel brand battery. If the battery is damaged and needs replacement, it is recommended to use the original battery. Here is the related information: 1. Peugeot 408: The dual lion-eye design of the headlights provides excellent visual effects. The front grille features a dot-matrix chrome decoration, giving it a dynamic look, complemented by the lion emblem in the center, adding a sporty touch. The dimensions of the car are 4750mm in length, 1820mm in width, and 1488mm in height, with a wheelbase of 2730mm. 2. Powertrain: The new Peugeot 408 is equipped with two engines: a 1.2T and a 1.6T, with maximum power outputs of 100 and 123 kilowatts respectively, and maximum torque of 230 and 245 Newton-meters.

My 408 is the 2016 1.6T model, originally equipped with a Varta T6 battery with 70Ah capacity. The battery models vary significantly across different year models of this car. For example, the 1.8L version uses the T7 model, and newer cars after 2019 may use AGM start-stop batteries. Last time when replacing the battery, the technician taught me three key points: the cold cranking current must not be lower than the factory value, the size must fit the battery tray perfectly, and the positive and negative terminal positions must match. Currently, the mainstream battery models on the market are EFB and AGM. Cars with start-stop systems must use AGM batteries, otherwise they will fail within a few months. I recommend you first take a photo of the old battery label to show the seller, and then check the parameters against the vehicle manual.

For the 408 battery replacement, it depends on the specific engine displacement. The older 1.6L models use the 60Ah L2-400 type, while the newer 1.6T models generally use the 70Ah T6. Some high-end versions with start-stop systems require the AGM-H6. When I went to the auto parts market to replace it, I found the battery tray size is very particular—too short and it wobbles, too long and it won't fit. Pay special attention to the cold cranking amps (CCA), which the factory requires to be between 540 and 760 amps. Also, a heads-up: the car's electrical system is sensitive. After replacement, you need to reset the power module with a diagnostic tool, or the start-stop function might fail. For peace of mind, it's better to get the original battery at the dealership. Although it costs 200 yuan more, it lasts four to five years.

The 408 battery has different generations. The first generation commonly uses the 60Ah L2-400. Current 1.6T models mostly use the 70Ah T6 type, with a cold cranking current of over 650A. For models with start-stop function, an AGM battery must be selected, as a regular battery would fail within three months. When replacing the battery, pay attention to the terminal size; the original vehicle uses thin tapered terminals. It is recommended to directly remove the old battery to check the label or use a vehicle matching software for inquiry. Brands like Varta or Fengfan are good choices, but never opt for cheap off-brand batteries.

The model for this car is quite complex. For the 2015 and earlier 408 models, they use a standard 60Ah lead-acid battery, model L2-400. Turbocharged models require a 70Ah T6 battery, while the newly introduced 1.8L version comes with an 80Ah T7. The most troublesome are those with start-stop functionality, which must use AGM technology batteries, typically model AGM-H6. Last time I replaced it myself, I found the battery compartment particularly narrow, so I recommend bringing a tape measure to check the dimensions. The key parameter is the cold cranking amps (CCA), with Peugeot requiring at least 650A. In terms of brands, Bosch offers good compatibility and comes with a two-year warranty.

The replacement for the Peugeot 408 mainly depends on the engine displacement. The 1.6L naturally aspirated older models use a 60Ah L2-400; the 1.6T recommends a 70Ah Varta T6 with a cold cranking current of 650A; the 1.8L version uses an 80Ah T7. Models with auto start-stop must use AGM batteries, as regular batteries will fail within three months. Pay attention to the size specifications when selecting a battery, as the original battery compartment design is very compact, and a slightly larger one won't fit. The newly introduced EFB batteries offer good cost-performance, being 30% cheaper than AGM, but for frequent start-stop usage, AGM is still recommended. Providing the VIN at the shop is the safest approach—don't guess the model yourself.
