Fulbat FDC6-400 AGM 6V 342Ah is a traction battery for industrial electric vehicles: forklifts, pallet trucks, elevating platforms, cleaning machines (scrubbers) and golf buggies. Built for deep discharges and 8-hour continuous work cycles.

The Fulbat FDC6-400 is a 342 Ah, 6 V deep-cycle battery for golf carts and electric utility vehicles. Its 295 × 180 × 428 mm and the positive terminal on the right make it the exact replacement for the 342 Ah battery fitted as standard to many golf carts.
With 342 Ah, the Fulbat FDC6-400 forms part of the battery banks of golf carts and electric utility vehicles. Always replace the complete set to avoid imbalance. Check that it matches your current battery in dimensions, terminals and hold-down: this reference has DT terminals.
Fulbat builds the FDC6-400 to the same standards as the rest of its catalogue; what changes between references is capacity, format and terminal position.
AGM means the acid is held in a glass mat instead of floating free. That is why the battery can be installed in the cabin without gases, survives more cycles and recovers its charge quickly.
The Fulbat FDC6-400 is made in the 295 × 180 × 428 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 DT 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 has manufactured in France since 1978 and specialises in motorcycles and light vehicles. Its catalogue is short and clear, covers almost the whole fleet and works only with sealed, leak-free batteries. We guarantee that every Fulbat arrives new, charged and with the manufacturer's full warranty.
Charge with a charger that has an AGM mode: it limits the voltage and protects the glass-fibre separators. Always replace all the batteries in the bank at once and use the charger specified by the vehicle manufacturer.
The Fulbat FDC6-400 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.
Orders placed before 6:00 pm 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 14 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.

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 (−) 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 devices with Start-Stop or BMS, register the battery via OBD so the alternator applies the correct charging profile.
Expected lifespan of the Fulbat FDC6-400 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.
Dimensions (length × width × height) are 295×180×428 mm — also written as 295x180x428 mm — 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.
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 devices. See the "Equivalents" section to view recommended options at the same performance level.
