12*V* Voltage
180*Ah* Capacity
1,000*A* Cold cranking
43*kg* Weight

The **Fulmen FJ1805 truck battery** is rated at **12 V**, **180 Ah** and **1,000 A** of cold cranking current (EN) from the **PowerPRO y Construction** range, and is prepared for trucks, buses, tractors and heavy machinery. Measuring 510 × 218 × 225 mm and the positive terminal on the left, it is the direct replacement for trucks fitted from the factory with a 180 Ah battery of this format.
- Good balance of capacity, cranking power and price.
- Resistant to constant chassis vibration.
- Powers tachograph, fridge and heater during rest stops.
- Better tolerance to deep discharge than a conventional starter battery.

### What the Fulmen FJ1805 is for

The Fulmen FJ1805 is designed for trucks, buses, tractors and heavy machinery. In 24 V installations with two batteries in series, replace both at the same time to avoid imbalance. Check that it matches your current battery in dimensions, terminals and hold-down: this reference has a weight of 43 kg, 1 terminals and B03 hold-down.

### Dimensions, polarity and mounting

The Fulmen FJ1805 is made in the 510 × 218 × 225 mm format and weighs 43 kg. The positive terminal on the left 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 B03 hold-down and 1 terminals, the system that anchors and connects it in the vehicle. Checking the three dimensions and the terminal position before buying avoids the most common mistake when replacing a battery.

### Fulmen: the maker behind the FJ1805

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 FJ1805: PowerPRO y Construction range and conventional lead-acid technology

The **PowerPRO y Construction** is the Fulmen range the FJ1805 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.
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.

### Care and maintenance

Keep the terminals clean and tight and the battery firmly secured against chassis vibration. In 24 V installations, check periodically that both batteries show the same voltage; an imbalance means one is failing.

### Warranty and coverage

The Fulmen FJ1805 comes with the **manufacturer's official warranty** against manufacturing defects. An important note for commercial vehicles: most trucks use **two batteries connected in series** (24 V installation). If you replace only one, the new battery works alongside the old one, which has already lost capacity; that imbalance shortens its life and the manufacturer may treat it as misuse. Always replace **both at the same time**.

### Delivery times and returns

Orders placed **before [[ks:cutoff]]** with the battery in stock ship the same day. Delivery in mainland Spain and Portugal takes 24-48 working hours; for the Balearic Islands and the rest of the European Union allow 3 to 5 working days. You have **[[ks:return_days]] days** to return an unused battery; in mainland Spain and Portugal collection is free. We email you the tracking number as soon as the parcel ships.

## Frequently asked questions

### How is the Fulmen FJ1805 battery installed in the vehicle?

In most trucks 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 left match the polarity shown on the product sheet; 6) connect the positive (+) first, then the negative (−). On trucks with Start-Stop or BMS, register the battery via OBD so the alternator applies the correct charging profile.

### How long does the Fulmen FJ1805 battery last?

Expected lifespan of the Fulmen FJ1805 is 4 to 6 years in regular truck 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 FJ1805 battery?

Dimensions (length × width × height) are 510×218×225 mm — also written as 510x218x225 mm — following the European DIN standard. Always measure the space in your truck before buying: even one extra millimetre can prevent the hold-down clamp from closing. The height shown includes the terminals.

### Which side is the positive terminal on this battery?

Polarity: positive on the left. 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.

### Does this battery fit my truck?

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 FJ1805 fits 290 verified vehicle versions in our database.

### Which interchangeable batteries are there for this one?

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 trucks. See the "Equivalents" section to view recommended options at the same performance level.
