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

The **Fulmen FG1803** with conventional lead-acid technology delivers **180 Ah** at **12 V** and **1,000 A** of cold cranking current (EN): what trucks, buses, tractors and heavy machinery demand. Measuring 513 × 223 × 223 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.
- Powers tachograph, fridge and heater during rest stops.
- Better tolerance to deep discharge than a conventional starter battery.
- Good balance of capacity, cranking power and price.
- Resistant to constant chassis vibration.

### Vehicles compatible with the Fulmen FG1803

The Fulmen FG1803 is compatible with more than 424 vehicles: it is fitted as original equipment or as a replacement by brands such as Fiat, New Holland, Case Ih, Carraro, Valmet and Case. For anyone who needs to replace the **battery in their Fiat** or New Holland, this Fulmen FG1803 reproduces the original specifications. The compatibility list also includes models from Valtra, Steyr, Same, Case International, Hurlimann, Lamborghini, Zetor and Komatsu. It covers 97 original-equipment references, one of the widest coverages in its format.

### Will it fit your current battery tray?

In terms of format, the Fulmen FG1803 measures 513 × 223 × 223 mm (length × width × height) and weighs 42.80 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 B00 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.

### The Fulmen FG1803: StartPRO range and conventional lead-acid technology

Within the Fulmen catalogue, the **StartPRO** series groups the references designed for this use. The FG1803 is the 180 Ah model of that family, with the same performance as its siblings in other sizes.
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.

### 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. We guarantee that every Fulmen arrives new, charged and with the manufacturer's full warranty.

### Manufacturer's warranty

The Fulmen FG1803 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**.

### 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.

### Shipping, delivery 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 fit the FG1803 model in my truck?

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 FG1803 battery last?

Expected lifespan of the Fulmen FG1803 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 FG1803 battery?

Dimensions (length × width × height) are 513×223×223 mm — also written as 513x223x223 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.

### What polarity does the Fulmen FG1803 battery have?

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.

### Will the Fulmen FG1803 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 FG1803 fits 141 verified vehicle versions in our database.

### Which batteries are equivalent to the Fulmen FG1803?

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.
