12*V* Voltage
64*Ah* Capacity
640*A* Cold cranking
14.90*kg* Weight

The **Fulmen FA640** from the **Formula Xtreme** range delivers **64 Ah** and **640 A** of cold cranking current (EN) at **12 V**: the usual specification for passenger cars with conventional starting, without a Start-Stop system. It measures 242 × 175 × 190 mm and the positive terminal on the right, the format sought by anyone replacing a 64 Ah battery in cars.
- Reliable cold starts, even after weeks without driving.
- Conventional lead-acid: the most proven and economical technology.
- Original-equipment build quality without the dealership price.
- Direct replacement for the original battery in size and terminals.

### What the Fulmen FA640 is for

With 64 Ah, the Fulmen FA640 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 14.90 kg, 1 terminals and B13 hold-down.

### Dimensions, polarity and mounting

It has external dimensions of 242 × 175 × 190 mm and weighs 14.90 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 and 1 terminals, 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.

### What Fulmen does differently

Fulmen is the historic French brand of the Exide group: batteries made on the same lines and with the same technology as original equipment, widely used by workshops across Europe. We guarantee that every Fulmen arrives new, charged and with the manufacturer's full warranty.

### The Fulmen FA640: Formula Xtreme range and conventional lead-acid technology

Within the Fulmen catalogue, the **Formula Xtreme** series groups the references designed for this use. The FA640 is the 64 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.

### Usage and maintenance tips

On batteries with filler caps, check the electrolyte level and top up only with distilled water. Avoid leaving lights or accessories on with the engine off: most batteries fail not through defects but through repeated deep discharges.

### Warranty and coverage

The Fulmen FA640 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.

### When you get it and how to return it

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 FA640 battery last?

Expected lifespan of the Fulmen FA640 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 dimensions of the Fulmen FA640 battery?

Dimensions (length × width × height) are 242×175×190 mm — also written as 242x175x190 mm and correspond to the European L2 case size — 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.

### Is the FA640 valid for my vehicle?

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 FA640 fits 178 verified vehicle versions in our database.

### What are the equivalents of the FA640 model?

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.
