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 110 Ah C20 πŸ”‹ Cold cranking 900 A EN-1 πŸ“ Dimensions 349Γ—175Γ—235 mm βš™οΈ Technology Lead-acid 🧭 Polarity Positive on the right βš–οΈ Weight 28,3 kg 🏷️ Model FULMEN PowerPRO Agriculture and Construction ## Description ## Truck battery Fulmen FJ1100 PowerPRO y Construction 110Ah 900A 12V 12*V* Voltage 110*Ah* Capacity 900*A* Cold cranking 28.30*kg* Weight The **Fulmen FJ1100** with conventional lead-acid technology delivers **110 Ah** at **12 V** and **900 A** of cold cranking current (EN): what trucks, buses, tractors and heavy machinery demand. Its 349 Γ— 175 Γ— 235 mm and the positive terminal on the right make it the exact replacement for the 110 Ah battery fitted as standard to many trucks. - Better tolerance to deep discharge than a conventional starter battery. - Powers tachograph, fridge and heater during rest stops. - Resistant to constant chassis vibration. - Good balance of capacity, cranking power and price. ### Will it fit your current battery tray? It has external dimensions of 349 Γ— 175 Γ— 235 mm and weighs 28.30 kg. The positive terminal on the right 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. 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 the Fulmen FJ1100 is for The Fulmen FJ1100 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 28.30 kg, 1 terminals and B00 hold-down. ### The Fulmen FJ1100: PowerPRO y Construction range and conventional lead-acid technology The **PowerPRO y Construction** is the Fulmen range the FJ1100 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. 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. ### Fulmen: the maker behind the FJ1100 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. All the Fulmen batteries in our catalogue are genuine product, recently manufactured and covered by the manufacturer's warranty. ### Official warranty The Fulmen FJ1100 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**. ### How to make it last longer In 24 V installations, check periodically that both batteries show the same voltage; an imbalance means one is failing. During rest stops with active loads, avoid repeated deep discharges: they shorten the life of any starter battery. ### Delivery times and returns Same-day dispatch from our warehouse for in-stock orders placed **before [[ks:cutoff]]**: 24-48 working hours in mainland Spain and Portugal, 3 to 5 days in the islands and the rest of Europe. Returns are accepted for **[[ks:return_days]] days** if the battery has not been used (free collection on the Iberian mainland). You will receive tracking by email. ## Frequently asked questions ### How is the Fulmen FJ1100 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 this page. 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€” 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 FJ1100 battery last? Expected lifespan of the Fulmen FJ1100 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 FJ1100 battery? Dimensions (length Γ— width Γ— height) are 349Γ—175Γ—235 mm β€” also written as 349x175x235 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. ### 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 β€” we reply during business hours (Mon–Fri 10:00–13:30 and 16:40–18:00 (Spanish time, CET)). The FJ1100 typically fits a wide range of European vehicles thanks to its standard DIN case format. ### 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 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 - [TUDOR TG1100](https://baterias.com/gb/battery-tudor-tg1100-110ah-750a) - [EXIDE EG1100](https://baterias.com/gb/battery-exide-eg1100-12v-110ah-750a) - [VARTA I9](https://baterias.com/gb/battery-varta-i9-12v-120ah-780a) - [Q-battery BATTERY-12SEM-120](https://baterias.com/gb/battery-q-battery-12sem-120-12v-120ah) - [Q-battery BATTERY-12TTB-115](https://baterias.com/gb/battery-q-battery-12ttb-115-12v-115ah) ## Technical team (editorial authorship) The FAQs, guides and comparisons on this site are reviewed by the baterias.com technical team β€” over 25 years of experience validating automotive batteries. β†’ https://baterias.com/gb/technical-team --- *baterias.com β€” Automotive batteries Β· 2026-10-01*
