It replaces the original battery without adaptation in cars with a 187 Γ— 127 Γ— 220 mm format: same 35 Ah capacity and the positive terminal on the right. - Direct replacement for the original battery in size and terminals. - Original-equipment build quality without the dealership price. - Conventional lead-acid: the most proven and economical technology. - Reliable cold starts, even after weeks without driving. ### What the Fulmen FB356 is for With 35 Ah, the Fulmen FB356 is sized for passenger cars with conventional starting, without a Start-Stop system. It is a direct replacement for the original battery as long as dimensions and terminals match. Check that it matches your current battery in dimensions, terminals and hold-down: this reference has a weight of 8.90 kg, 3 terminals and B00 hold-down. ### Will it fit your current battery tray? The Fulmen FB356 is made in the 187 Γ— 127 Γ— 220 mm format and weighs 8.90 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 3 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. ### The Fulmen FB356: Formula range and conventional lead-acid technology The **Formula** is the Fulmen range the FB356 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. ### What Fulmen does differently 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 FB356 comes with the **manufacturer's official warranty** against manufacturing defects; the exact period is stated in the brand's conditions. If it fails through a defect within the period, we replace it free of charge. ### Usage and maintenance tips Avoid leaving lights or accessories on with the engine off: most batteries fail not through defects but through repeated deep discharges. On batteries with filler caps, check the electrolyte level and top up only with distilled water. ### When you get it and how to return it 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 change this battery step by step? In most cars 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 cars with Start-Stop or BMS, register the battery via OBD so the alternator applies the correct charging profile. ### How long does the Fulmen FB356 battery last? Expected lifespan of the Fulmen FB356 is 4 to 6 years in regular car 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 FB356 model? Dimensions (length Γ— width Γ— height) are 187Γ—127Γ—220 mm β€” also written as 187x127x220 mm β€” following the European DIN standard. Always measure the space in your car before buying: even one extra millimetre can prevent the hold-down clamp from closing. The height shown includes the terminals. ### Is the FB356 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 FB356 typically fits a wide range of European vehicles thanks to its standard DIN case format. ### What are the equivalents of the FB356 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 cars. See the "Equivalents" section to view recommended options at the same performance level. ## Equivalent batteries - [TUDOR TB356](https://baterias.com/gb/battery-tudor-tb356-35ah-240a) - [EXIDE EB356](https://baterias.com/gb/battery-exide-eb356-12v-35ah-240a) - [TUDOR TA386](https://baterias.com/gb/battery-tudor-ta386-12v-38ah-300a) ## 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· 2026-10-08*
