Leisure battery Fulbat FDC12-145 122Ah 12V
For motorhomes, caravans and campers that need power off-grid, the Fulbat FDC12-145 provides 122 Ah of energy with AGM technology. It replaces the original battery without adaptation in motorhomes and caravans with a 340 × 172 × 286 mm format: same 122 Ah capacity and the positive terminal on the left.
- Sealed and gas-free: suitable for installation inside the living area.
- Low self-discharge during months of storage.
- AGM technology: absorbed electrolyte, no spills, can be mounted at an angle.
- Power for fridge, lighting, water pump and USB off-grid.
What the Fulbat FDC12-145 is for
The Fulbat FDC12-145 is designed for motorhomes, caravans and campers that need power off-grid: it powers fridge, lights, pump and chargers for several days off-grid. Its 122 Ah capacity sets the available autonomy. Check that it matches your current battery in dimensions, terminals and hold-down: this reference has BOLT-M6 terminals.
Will it fit your current battery tray?
It has external dimensions of 340 × 172 × 286 mm. 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. It uses BOLT-M6 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.
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 FDC12-145
The FDC12-145 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.
AGM (Absorbent Glass Mat) technology seals the electrolyte in glass microfibre. The result is a maintenance-free battery that is highly vibration-resistant and able to withstand deep discharges that would ruin a classic lead-acid battery.
Usage and maintenance tips
During months of storage, keep it charged with a mains charger or a small solar panel; a battery left discharged for weeks loses capacity permanently. Charge with a charger that has an AGM mode: it limits the voltage and protects the glass-fibre separators.
Manufacturer's warranty
The Fulbat FDC12-145 comes with the manufacturer's official warranty against manufacturing defects. Avoid repeated full discharges: they shorten its life and are not covered.
Shipping, delivery and returns
Order before 6:00 pm 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 14 days to return it if it has not been installed, with free collection on the mainland, and shipment tracking by email.

Frequently asked questions
Is the Fulbat FDC12-145 AGM an AGM battery and what are the benefits of AGM?
Yes. The FDC12-145 AGM from Fulbat uses AGM (Absorbent Glass Mat) technology: a sealed lead-acid battery where the electrolyte is absorbed in a glass-fibre mat. It withstands more charge/discharge cycles than a conventional one, handles heat better and is the required technology for caravans with advanced Start-Stop and regenerative braking. Expected lifespan: 5-8 years under normal conditions.
How much energy does this battery give a caravan?
It stores about 1,464 Wh. To make it last, it should not be discharged below half, so you have about 732 Wh usable: for example, an average load of 50 W for about 15 hours.
Can it be charged with solar panels?
Yes, with a charge controller (PWM or MPPT) set for AGM. It can also be charged by the vehicle alternator (ideally with a DC-DC charger) and by the 230 V charger when you are on hook-up at the campsite.
What are the dimensions of the Fulbat FDC12-145 AGM battery?
Dimensions (length × width × height) are 340×172×286 mm — also written as 340x172x286 mm — following the European DIN standard. Always measure the space in your caravan before buying: even one extra millimetre can prevent the hold-down clamp from closing. The height shown includes the terminals.
On which side is the positive of the FDC12-145 AGM model?
Polarity: positive on the left. To identify it, place the battery in front of you with the terminals facing you and check which side the positive (+, marked with a red ring) is on. Before buying, verify the polarity matches your current battery: switching polarity forces longer cables or system reconfiguration, with short-circuit risk.
