Vibration-resistant, withstands long cold-diesel cranks and deep discharges during parking with active loads (tachograph, refrigeration, heater). ## 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 145 Ah C20 πŸ”‹ Cold cranking 1000 A EN-1 πŸ“ Dimensions 360Γ—253Γ—240 mm βš™οΈ Technology Lead-acid βš–οΈ Weight 38,1 kg 🏷️ Model FULMEN StartPRO ## Description ## Truck battery Fulmen FG145A StartPRO 145Ah 1,000A 12V 12*V* Voltage 145*Ah* Capacity 1,000*A* Cold cranking 38.10*kg* Weight With **145 Ah** and **1,000 A** of cold cranking current (EN), the **Fulmen FG145A** from the **StartPRO** range is built for professional use in trucks, buses, tractors and heavy machinery. It measures 360 Γ— 253 Γ— 240 mm, the format sought by anyone replacing a 145 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 FG145A is for Designed for trucks, buses, tractors and heavy machinery, the Fulmen FG145A withstands constant chassis vibration and discharges during stops with active loads. Check that it matches your current battery in dimensions, terminals and hold-down: this reference has a weight of 38.10 kg, 1 terminals and B00 hold-down. ### Size, terminals and hold-down of the Fulmen FG145A In terms of format, the Fulmen FG145A measures 360 Γ— 253 Γ— 240 mm (length Γ— width Γ— height) and weighs 38.10 kg. 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. ### Fulmen: the maker behind the FG145A 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. ### The Fulmen FG145A: StartPRO range and conventional lead-acid technology The FG145A is part of the Fulmen **StartPRO** range. Choosing the right reference within the series comes down to capacity, dimensions and terminals: technology and quality are common to the whole family. 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. ### Usage and maintenance tips On batteries with filler caps, check the electrolyte level and top up only with distilled water. Keep the terminals clean and tight and the battery firmly secured against chassis vibration. ### Official warranty The Fulmen FG145A 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**. ### Delivery times 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 is the Fulmen FG145A 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 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€” 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. ### What is the service life of the FG145A model? Expected lifespan of the Fulmen FG145A 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 size is this battery? Dimensions (length Γ— width Γ— height) are 360Γ—253Γ—240 mm β€” also written as 360x253x240 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. ### Will the Fulmen FG145A 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 FG145A typically fits a wide range of European vehicles thanks to its standard DIN case format. ### Which batteries are equivalent to the Fulmen FG145A? 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 TG145A](https://baterias.com/gb/battery-tudor-tg145a-145ah-1000a) - [EXIDE EG145A](https://baterias.com/gb/battery-exide-eg145a-12v-145ah-1000a) ## 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*
