It replaces the original battery without adaptation in motorcycles with a 175 × 87 × 155 mm format: same 12 Ah capacity and the positive terminal on the left. - Minimal self-discharge: ready to use all season. - Thousands of cycles of service life. - LiFePO4 lithium: minimal weight and almost zero self-discharge. - Up to 70% less weight than an equivalent lead-acid battery. ### What the Fulbat FLTX20H is for With its reduced weight, the Fulbat FLTX20H is a popular upgrade on sport, off-road and restored classic bikes looking to shed kilos. Check that it matches your current battery in dimensions, terminals and hold-down: this reference has a weight of 2.30 kg. ### Will it fit your current battery tray? The Fulbat FLTX20H is made in the 175 × 87 × 155 mm format and weighs 2.30 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. Before replacing it, measure your current battery tray: if all three dimensions and the terminal positions match, the swap is direct and needs no adapters. ### What Fulbat does differently French brand Fulbat is a European reference in motorcycle, garden and leisure batteries: compact ranges, clear JIS codes and a consistent quality that workshops know well. All the Fulbat batteries in our catalogue are genuine product, recently manufactured and covered by the manufacturer's warranty. ### Technology inside the Fulbat FLTX20H The FLTX20H is one of the Fulbat references for this type of use; it shares the same manufacturing and quality-control criteria as the rest of the brand's catalogue. A LiFePO4 battery starts with the same nominal voltage as a lead-acid one but with far less weight and a service life several times longer. It requires a lithium-compatible charger. ### Care and maintenance Check that the bike's regulator does not exceed 14.6 V; if the vehicle stands for long periods, an occasional maintenance charge is enough. Store the battery at 50-70% charge if it will be unused for months. ### Official warranty The Fulbat FLTX20H comes with the **manufacturer's official warranty**. Always charge with a LiFePO4-compatible charger: a lead-acid charger with a desulphation phase can damage it and void the warranty. ### 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 Fulbat FLTX20H battery installed in the vehicle? 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 (−) 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 — match the polarity shown on the product sheet; 6) connect the positive (+) first, then the negative (−). On cars 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 FLTX20H model? Expected lifespan of the Fulbat FLTX20H is 4 to 7 years in regular use (depends on technology and climate). 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 Fulbat FLTX20H battery? Dimensions (length × width × height) are 175×87×155 mm — also written as 175x87x155 mm — 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. ### 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 — 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. ## Technical team (editorial authorship) The FAQs, guides and comparisons on this site are reviewed by the baterias.com technical team — over 25 years of experience validating automotive batteries. → https://baterias.com/gb/technical-team --- *baterias.com — Automotive batteries · 2026-10-02*
