Its reinforced grid and AGM/GEL separator extend the number of useful cycles well beyond a conventional starter battery. ## Why this deep-cycle battery? - **Daily cycling without wear** handles deep discharges without losing capacity - **Sealed AGM/GEL** no maintenance, no risk of spills - **Thousands of useful cycles** over its full lifetime πŸ”Œ Voltage 12 V ⚑ Capacity 34 Ah C20 πŸ“ Dimensions 268Γ—78Γ—171 mm βš™οΈ Technology AGM 🧭 Polarity Positive on the right ## Description ## Mobility battery Fulbat FDC12-43 34Ah 12V 12*V* Voltage 34*Ah* Capacity The **Fulbat FDC12-43** with AGM technology delivers **34 Ah** at **12 V** with the cycle life that power wheelchairs, mobility scooters and light electric vehicles demand. It replaces the original battery without adaptation in power wheelchairs and mobility scooters with a 267 Γ— 77 Γ— 171 mm format: same 34 Ah capacity and the positive terminal on the right. - AGM technology: absorbed electrolyte, no spills, can be mounted at an angle. - Designed to be discharged and recharged daily without losing capacity. - Thousands of useful cycles over its lifetime. - Standard replacement format for wheelchairs and scooters. ### What the Fulbat FDC12-43 is for The Fulbat FDC12-43 is the usual replacement in power wheelchairs, mobility scooters and light electric vehicles. Recharge after each use and avoid leaving it discharged for days. Check that it matches your current battery in dimensions, terminals and hold-down: this reference has BOLT-M8 terminals. ### Technology inside the Fulbat FDC12-43 Fulbat builds the FDC12-43 to the same standards as the rest of its catalogue; what changes between references is capacity, format and terminal position. In an AGM battery the electrolyte is absorbed in glass-fibre separators: there is no free liquid, it cannot spill and it can be mounted at an angle. That construction lowers internal resistance, speeds up recharging and multiplies cycle life compared with a conventional battery. ### Size, terminals and hold-down of the Fulbat FDC12-43 The Fulbat FDC12-43 is made in the 267 Γ— 77 Γ— 171 mm format. 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 BOLT-M8 terminals, the system that anchors and connects it in the vehicle. 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. ### Fulbat: the maker behind the FDC12-43 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. At baterias.com we work directly with the manufacturer or its official distributor: real stock, brand-new product and official warranty. ### How to make it last longer Charge with a charger that has an AGM mode: it limits the voltage and protects the glass-fibre separators. Recharge the wheelchair or scooter after each use and do not leave it discharged for days: lead sulphates and loses capacity. ### Official warranty The Fulbat FDC12-43 comes with the **manufacturer's official warranty** against manufacturing defects. If it fails through a defect within the warranty period, we replace it at no cost to you. ### When you get it and how to return it Orders placed **before [[ks:cutoff]]** with the battery in stock ship the same day. Delivery in mainland Spain and Portugal takes 24-48 working hours; for the Balearic Islands and the rest of the European Union allow 3 to 5 working days. You have **[[ks:return_days]] days** to return an unused battery; in mainland Spain and Portugal collection is free. We email you the tracking number as soon as the parcel ships. ## Frequently asked questions ### How is the Fulbat FDC12-43 AGM battery installed in the vehicle? In most devices 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 devices 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 FDC12-43 AGM model? Expected lifespan of the Fulbat FDC12-43 AGM 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 measurements of the FDC12-43 AGM model? Dimensions (length Γ— width Γ— height) are 268Γ—78Γ—171 mm β€” also written as 268x78x171 mm β€” following the European DIN standard. Always measure the space in your device before buying: even one extra millimetre can prevent the hold-down clamp from closing. The height shown includes the terminals. ### What are the equivalents of the FDC12-43 AGM 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 devices. 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 β€” automotive battery specialists since 2012. β†’ https://baterias.com/gb/technical-team --- *baterias.com β€” Automotive batteries Β· 2026-10-19*
