It measures 230 Γ— 173 Γ— 222 mm and the positive terminal on the right, the format sought by anyone replacing a 65 Ah battery in cars. - Reliable cold starts, even after weeks without driving. - Conventional lead-acid: the most proven and economical technology. - Original-equipment build quality without the dealership price. - Direct replacement for the original battery in size and terminals. ### What the Fulmen FA654 is for The Fulmen FA654 covers the needs of passenger cars with conventional starting, without a Start-Stop system: reliable starting, stable voltage for the electronics and a service life of several years in daily use. Check that it matches your current battery in size and terminal position. Check that it matches your current battery in dimensions, terminals and hold-down: this reference has a weight of 16 kg, 1 terminals and Korean B1 hold-down. ### Will it fit your current battery tray? The Fulmen FA654 is made in the 230 Γ— 173 Γ— 222 mm format and weighs 16 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 Korean B1 hold-down and 1 terminals, the system that anchors and connects it in the vehicle. Checking the three dimensions and the terminal position before buying avoids the most common mistake when replacing a battery. ### The Fulmen FA654: Formula Xtreme range and conventional lead-acid technology The FA654 is part of the Fulmen **Formula Xtreme** range. Choosing the right reference within the series comes down to capacity, dimensions and terminals: technology and quality are common to the whole family. Conventional lead-acid is the benchmark against which other technologies are compared: good cranking current, great tolerance to alternator charging and the best price per amp-hour. ### Fulmen: the maker behind the FA654 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. ### Manufacturer's warranty The Fulmen FA654 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. ### How to make it last longer On batteries with filler caps, check the electrolyte level and top up only with distilled water. In normal daily use the alternator keeps the battery charged; if the car stands for weeks, a maintenance charge once a month prevents deep discharge. ### 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 FA654 model in my car? 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 FA654 battery last? Expected lifespan of the Fulmen FA654 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 dimensions of the Fulmen FA654 battery? Dimensions (length Γ— width Γ— height) are 230Γ—173Γ—222 mm β€” also written as 230x173x222 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 FA654 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 FA654 typically fits a wide range of European vehicles thanks to its standard DIN case format. ### Which batteries are equivalent to the Fulmen FA654? 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 TA654](https://baterias.com/gb/battery-tudor-ta654-12v-65ah-580a) - [TUDOR TB604](https://baterias.com/gb/battery-tudor-tb604-60ah-390a) - [EXIDE EA654](https://baterias.com/gb/battery-exide-ea654-12v-65ah-580a) - [EXIDE EB604](https://baterias.com/gb/battery-exide-eb604-12v-60ah-390a) ## 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· 2026-10-03*
