Truck battery Fulmen FG1803 StartPRO 180Ah 1,000A 12V
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.
In short: the Fulmen FG1803 (180 Ah, 1000 A, 513 × 223 × 223 mm, positive terminal on the left). Verified equivalent alternatives: Varta M18 and Exide EG1803.
- 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 6:00 pm 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 14 days to return it if it has not been installed, with free collection on the mainland, and shipment tracking by email.

Frequently asked questions
Why does my lorry have two batteries?
Most lorries, buses and tractors run on 24 V with two 12 V batteries connected in series. Always replace both at the same time and with the same model: if one is new and the other old, they become unbalanced and both last less.
How long does the Fulmen FG1803 battery last?
As a guide, you can expect the Fulmen FG1803 to last 4 to 6 years in normal lorry use, although the real figure may be higher or lower. It can vary considerably with usage (short or long journeys), temperature, the condition of the alternator and charging system, power drawn with the engine off and maintenance, plus the truck itself and Start-Stop. Cold demands more at every start and intense heat evaporates the electrolyte.
What are the dimensions of the Fulmen FG1803 battery?
Length × width × height: 513x223x223 mm. Height is measured to the top of the terminals. Measure your truck's battery tray first; if the battery exceeds it by even a millimetre, the hold-down clamp may not close.
What polarity does the Fulmen FG1803 battery have?
On the Fulmen FG1803, the polarity is positive on the left. To check, stand the battery in front of you with the terminals nearest you: the positive (+) is the one with the red ring. A change of polarity from the original means longer cables or a reconfigured system and can cause a short circuit: check it before ordering.
Will the Fulmen FG1803 battery fit my truck?
Not sure? Try your number plate in the finder (DGT/DVLA/KBA detect model and engine) or the "Compatible vehicles" tab, checked by our technical team; if your truck is not there, send us make, model, engine and year on WhatsApp and we will reply during business hours (Mon–Fri 10:00–13:30 and 16:30–18:00 (Spanish time, CET)). If our table and the truck handbook disagree, go with what the manufacturer says. Our database holds 141 verified vehicle versions for the Fulmen FG1803.
Which batteries are equivalent to the Fulmen FG1803?
To replace the Fulmen FG1803 without modifications, the other battery must be identical in size, polarity, Ah and CCA. The "Equivalents" section of this page gathers the recommended options with equivalent performance; remember that in Start-Stop trucks an EFB should not be replaced with a conventional battery.
Fulmen FG1803 or Varta M12: which one to choose?
