Withstands constant chassis vibration, supports long cold-engine cranks and keeps auxiliary services running (tachograph, heater, refrigeration, GPS) during driver's mandatory rest stops. ## Why this truck battery? - **True Heavy Duty** built for intensive professional use - **Long cold-diesel cranks** reliable even in extreme cold - **Powers services at idle** tachograph, heater and lights with engine off πŸ”Œ Voltage 12 V ⚑ Capacity 152 Ah C20 πŸ”‹ Cold cranking 1130 A EN-1 πŸ“ Dimensions 513Γ—189Γ—223 mm βš™οΈ Technology Lead-acid 🧭 Polarity Positive on the left βš–οΈ Weight 40,3 kg 🏷️ Model FULMEN PowerPRO Agriculture and Construction ## Description ## Truck battery Fulmen FJ1523 PowerPRO y Construction 152Ah 1,130A 12V 12*V* Voltage 152*Ah* Capacity 1,130*A* Cold cranking 40.30*kg* Weight With **152 Ah** and **1,130 A** of cold cranking current (EN), the **Fulmen FJ1523** from the **PowerPRO y Construction** range is built for professional use in trucks, buses, tractors and heavy machinery. It measures 513 Γ— 189 Γ— 223 mm and the positive terminal on the left, the format sought by anyone replacing a 152 Ah battery in trucks. - Designed for 24 V installations with two batteries in series. - Powerful cold cranking for large-displacement diesel engines. - Heavy Duty construction for intensive professional use. - Conventional lead-acid: the most proven and economical technology. ### What the Fulmen FJ1523 is for With 152 Ah, the Fulmen FJ1523 cranks large-displacement diesel engines in the cold and powers tachograph, fridge and heater during rest stops. Check that it matches your current battery in dimensions, terminals and hold-down: this reference has a weight of 40.30 kg and B00 hold-down. ### The Fulmen FJ1523: PowerPRO y Construction range and conventional lead-acid technology The **PowerPRO y Construction** is the Fulmen range the FJ1523 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. ### Will it fit your current battery tray? It has external dimensions of 513 Γ— 189 Γ— 223 mm and weighs 40.30 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, 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. ### What Fulmen does differently 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. We guarantee that every Fulmen arrives new, charged and with the manufacturer's full warranty. ### How to make it last longer During rest stops with active loads, avoid repeated deep discharges: they shorten the life of any starter battery. On batteries with filler caps, check the electrolyte level and top up only with distilled water. ### Manufacturer's warranty The Fulmen FJ1523 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**. ### 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 FJ1523 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 (βˆ’) 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 β€” with positive on the left match the polarity shown on the product sheet; 6) connect the positive (+) first, then the negative (βˆ’). 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 FJ1523 battery last? Expected lifespan of the Fulmen FJ1523 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 measurements of the FJ1523 model? Dimensions (length Γ— width Γ— height) are 513Γ—189Γ—223 mm β€” also written as 513x189x223 mm β€” 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. ### Is the FJ1523 valid for my vehicle? 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 β€” we reply during business hours (Mon–Fri 10:00–13:30 and 16:40–18:00 (Spanish time, CET)). The FJ1523 typically fits a wide range of European vehicles thanks to its standard DIN case format. ### What are the equivalents of the FJ1523 model? 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 β€” 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. ## Equivalent batteries - [VARTA M11](https://baterias.com/gb/battery-varta-m11-12v-154ah-1150a) ## Technical team (editorial authorship) The FAQs, guides and comparisons on this site are reviewed by the baterias.com technical team β€” automotive battery specialists since 2012. β†’ https://baterias.com/gb/technical-team --- *baterias.com β€” Automotive batteries Β· 2026-10-20*
