The **Fulmen FC400 car battery** is rated at **12 V**, **40 Ah** and **320 A** of cold cranking current (EN) from the **Standard** range, and is designed for passenger cars with conventional starting, without a Start-Stop system. It measures 175 × 175 × 190 mm and the positive terminal on the right, the format sought by anyone replacing a 40 Ah battery in cars.
- Original-equipment build quality without the dealership price.
- Direct replacement for the original battery in size and terminals.
- Reliable cold starts, even after weeks without driving.
- Conventional lead-acid: the most proven and economical technology.

### What the Fulmen FC400 is for

With 40 Ah, the Fulmen FC400 is sized for passenger cars with conventional starting, without a Start-Stop system. It is a direct replacement for the original battery as long as dimensions and terminals match. Check that it matches your current battery in dimensions, terminals and hold-down: this reference has a weight of 10.40 kg and B13 hold-down.

### Dimensions, polarity and mounting

The Fulmen FC400 is made in the 175 × 175 × 190 mm format and weighs 10.40 kg. The positive terminal on the right decides which side the cables end up on: it is the detail that causes most buying mistakes, so check it before ordering. It uses a B13 hold-down, the system that anchors and connects it in the vehicle. For a direct replacement, the current battery tray must accept these dimensions and the same terminal layout; otherwise adapters will be needed or the hold-down will change.

### Why choose Fulmen batteries

With more than a century of history, Fulmen offers complete ranges for cars, trucks, motorcycles and leisure with the industrial quality of the Exide group. At baterias.com we work directly with the manufacturer or its official distributor: real stock, brand-new product and official warranty.

### The Fulmen FC400: Standard range and conventional lead-acid technology

Within the Fulmen catalogue, the **Standard** series groups the references designed for this use. The FC400 is the 40 Ah model of that family, with the same performance as its siblings in other sizes.
In a conventional battery the electrolyte is liquid and the lead plates are immersed in it. It is a mature, economical and easily recycled technology, ideal for starting vehicles in normal use.

### How to make it last longer

Avoid leaving lights or accessories on with the engine off: most batteries fail not through defects but through repeated deep discharges. Keep the terminals clean and tight, and check that the resting voltage does not drop below 12.4 V: below that it is time to recharge.

### Warranty and coverage

The Fulmen FC400 comes with the **manufacturer's official warranty** against manufacturing defects; the exact period is stated in the brand's conditions. If it fails through a defect within the period, we replace it free of charge.

### Delivery times and returns

Order **before [[ks:cutoff]]** with stock available and it leaves today: mainland Spain and Portugal receive it in 24-48 working hours, the islands and the rest of the EU in 3 to 5 days. You have **[[ks:return_days]] days** to return it if it has not been installed, with free collection on the mainland, and shipment tracking by email.

## Frequently asked questions

### How do I change this battery step by step?

In most cars it fits in 15-30 minutes with a 10 mm wrench; if the battery is under the seat or in the boot the time can double. See the step-by-step guide on this page. Quick summary: 1) switch off the engine and remove the key; 2) locate the original battery (engine bay, boot or under seat); 3) disconnect the negative (−) terminal first, then the positive (+); 4) loosen the hold-down clamp and remove the old battery; 5) fit the new one in the same orientation — match the polarity shown on the product sheet; 6) connect the positive (+) first, then the negative (−). On cars with Start-Stop or BMS, register the battery via OBD so the alternator applies the correct charging profile.

### How long does the Fulmen FC400 battery last?

Expected lifespan of the Fulmen FC400 is 4 to 6 years in regular car use without Start-Stop. In cold regions it drops slightly due to cold-start stress; in very hot regions it also drops because of electrolyte evaporation. To extend its life: avoid deep discharges (headlights on with engine off), have the alternator checked yearly, and keep the battery clean and properly secured.

### What are the measurements of the FC400 model?

Dimensions (length × width × height) are 175×175×190 mm — also written as 175x175x190 mm — following the European DIN standard. Always measure the space in your car before buying: even one extra millimetre can prevent the hold-down clamp from closing. The height shown includes the terminals.

### Will the Fulmen FC400 battery fit my car?

Three options to confirm: 1) enter your number plate in the finder (DGT/DVLA/KBA auto-detect your model and engine); 2) check the "Compatible vehicles" tab on this page, where we list every vehicle verified by our technical team; 3) if you cannot find your model, message us on WhatsApp with brand, model, engine and year — we reply during business hours (Mon–Fri 10:00–13:30 and 16:40–18:00 (Spanish time, CET)). The FC400 typically fits a wide range of European vehicles thanks to its standard DIN case format.

### Which batteries are equivalent to the Fulmen FC400?

Directly interchangeable batteries (same dimensions, same polarity, same Ah and CCA) are the OEM equivalents from leading brands: Bosch, Tudor, Exide and, depending on the model, Banner or Yuasa. Exact equivalence depends on technology — an EFB cannot be replaced with a conventional battery in Start-Stop cars. See the "Equivalents" section to view recommended options at the same performance level.
