Fulmen FE1403 StrongPRO EFB+ · Truck battery 140Ah 800A

Yes. The Fulmen FE1403 uses EFB (Enhanced Flooded Battery) technology, that is, flooded lead-acid with plates reinforced by additives. For cycles it sits between a conventional battery and an AGM, and it costs less than an equivalent AGM; it is the technology for trucks with basic Start-Stop, without regenerative braking.

Yes. It is a EFB battery of 140 Ah, designed for vehicles with Start-Stop. EFB batteries cover basic Start-Stop (no regenerative braking). Basic Start-Stop: EFB. Start-Stop with regenerative braking: AGM, which withstands more cycles. Check the handbook for the technology the truck manufacturer requires. Once fitted it is ready to go; registering it via OBD, advisable on most modern models, lets the alternator charge with the optimum profile.

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.

Estimated lifespan of the Fulmen FE1403: 5 to 7 years in lorry use, even with high power draw while parked. Treat it as an approximate guide, as every case is different. What weighs most: temperature (cold makes starts harder and intense heat evaporates the electrolyte), frequent short trips, the condition of the alternator and charging system, power draw while parked and maintenance, not forgetting the type of truck and Start-Stop.

Length × width × height: 513x189x223 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.

The FE1403 has the positive on the left: that is its polarity. Face the battery with its terminals nearest you and see which side the positive post (+, red ring) is on. A change of polarity from the original means longer cables or a reconfigured system and can cause a short circuit: check it before ordering.

Three routes: the "Compatible vehicles" tab on this page, with the vehicles verified by our technical team; your number plate in the finder, from which DGT/DVLA/KBA detect model and engine; and WhatsApp, with make, model, engine and year, during business hours (Mon–Fri 10:00–13:30 and 16:30–18:00 (Spanish time, CET)). According to our data, 360 verified vehicle versions are compatible with the FE1403. If our table and the truck handbook disagree, go with what the manufacturer says.

See the "Equivalents" section of this page for the recommended options at the same performance level. Mind the technology: in Start-Stop trucks an EFB is not swapped for a conventional battery. A direct equivalent needs what this FE1403 offers: 513×189×223 mm, positive on the left, the same Ah and CCA and EFB technology.

It is the AGM of the same case: more cycles, more cranking and better resistance to power draw at standstill than the FE1403. Compared with the FE1403 it has 100 A of cold cranking less. It costs €269.80 more. Essential if the vehicle requires AGM from the factory or draws a lot with the engine off; in conventional use the FE1403 does the job and AGM adds service life.

It is the verified Tudor equivalent for the FE1403 tray. Compared with the FE1403 it has the same Ah and cranking power. It costs €235.90 more. Decide by price, brand preference and availability: both fit and crank the same.

EFB is the right technology if your truck came with one from the factory (moving up to AGM is optional and the gain marginal). If it came with an AGM, fit an AGM instead. Thicker grids plus carbon and polyethylene additives in the plates: that is what sets an EFB apart from a conventional flooded battery. The result is more cycles and more resistance to deep discharges, without reaching AGM level. Renault Energy TCe, Peugeot/Citroën PureTech, Fiat MultiAir, Hyundai/Kia ISG and Ford EcoBoost are examples of basic Start-Stop (no regenerative braking) fitted with it from new.

Advisable, yes; essential, on most trucks, no. Registering it via OBD makes the alternator charge with the optimum profile from the first minute and extends battery life, which matters most on brands with sophisticated BMS such as BMW, Mercedes, Audi, Volvo or Land Rover. Without registration there is no starting problem: the alternator adjusts the profile within a few days. A workshop only needs an OBD scanner and a few minutes.
