## Description

## Car battery Fulmen FB442 Formula 44Ah 420A 12V

12*V* Voltage
44*Ah* Capacity
420*A* Cold cranking
10.60*kg* Weight

The **Fulmen FB442** from the **Formula** range delivers **44 Ah** and **420 A** of cold cranking current (EN) at **12 V**: the usual specification for passenger cars with conventional starting, without a Start-Stop system. Its 207 × 175 × 175 mm and the positive terminal on the right make it the exact replacement for the 44 Ah battery fitted as standard to many cars.
- Stable voltage for the vehicle electronics (ECU, sensors, climate control).
- Good balance of capacity, cranking power and price.
- Designed to last several years under normal daily use.
- Low self-discharge: copes with long stops without losing charge.

### Will it fit your current battery tray?

It has external dimensions of 207 × 175 × 175 mm and weighs 10.60 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.

### Vehicles compatible with the Fulmen FB442

The Fulmen FB442 is compatible with more than 321 vehicles: it is fitted as original equipment or as a replacement by brands such as Ford, Renault, Opel, Vauxhall, Nissan and Westfield. For anyone who needs to replace the **battery in their Ford** or Renault, this Fulmen FB442 reproduces the original specifications. It also appears as a replacement in vehicles from Volkswagen, Suzuki, Lotus, Rover, Chevrolet, Seat, Fiat and Citroën, among other manufacturers. In our database it is cross-referenced against 102 original-equipment part numbers, which gives an idea of its real coverage.

### The Fulmen FB442: Formula range and conventional lead-acid technology

The **Formula** is the Fulmen range the FB442 belongs to: it shares the same construction and quality criteria with the rest of the series, and varies in capacity and format to suit each vehicle.
The conventional lead-acid battery remains the most widespread technology thanks to its balance of capacity, cranking current and price. Well maintained and kept charged, it offers years of reliable service in vehicles without Start-Stop.

### Fulmen: the maker behind the FB442

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. At baterias.com we work directly with the manufacturer or its official distributor: real stock, brand-new product and official warranty.

### Official warranty

The Fulmen FB442 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.

### How to make it last longer

On batteries with filler caps, check the electrolyte level and top up only with distilled water. In normal daily use the alternator keeps the battery charged; if the car stands for weeks, a maintenance charge once a month prevents deep discharge.

### Shipping, delivery and returns

Same-day dispatch from our warehouse for in-stock orders placed **before 6:00 pm**: 24-48 working hours in mainland Spain and Portugal, 3 to 5 days in the islands and the rest of Europe. Returns are accepted for **14 days** if the battery has not been used (free collection on the Iberian mainland). You will receive tracking by email.

## Frequently asked questions

### How is the Fulmen FB442 battery installed in the vehicle?

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 our blog. 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 — with positive on the right 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.

### What is the service life of the FB442 model?

Expected lifespan of the Fulmen FB442 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 size is this battery?

Dimensions (length × width × height) are 207×175×175 mm — also written as 207x175x175 mm and correspond to the European LB1 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.

### On which side is the positive of the FB442 model?

Polarity: positive on the right. To identify it, place the battery in front of you with the terminals facing you and check which side the positive (+, marked with a red ring) is on. Before buying, verify the polarity matches your current battery: switching polarity forces longer cables or system reconfiguration, with short-circuit risk.

### Will the Fulmen FB442 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 FB442 fits 306 verified vehicle versions in our database.

### Which batteries are equivalent to the Fulmen FB442?

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.
