Stationary battery Fulbat FP6-12 12Ah 6V

6VVoltage
12AhCapacity

The 6 V, 12 Ah Fulbat FP6-12 stationary battery with AGM technology is designed for UPS, alarms, telecoms and emergency lighting. Measuring 151 × 50 × 100 mm and the positive terminal on the left, it is the direct replacement for UPS, alarm and emergency systems fitted from the factory with a 12 Ah battery of this format.

  • Low self-discharge and high reliability.
  • Standard format for UPS and emergency systems.
  • AGM: faster recharging and better cycle resistance than a conventional battery.
  • Instant response to mains failures.

Size, terminals and hold-down of the Fulbat FP6-12

The Fulbat FP6-12 is made in the 151 × 50 × 100 mm format. 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 FASTON-6.35 terminals, the system that anchors and connects it in the vehicle. For a direct replacement, the current battery tray must accept these dimensions and the same terminal layout; otherwise adapters will be needed or the hold-down will change.

What the Fulbat FP6-12 is for

Designed for UPS, alarms, telecoms and emergency lighting, the Fulbat FP6-12 is sealed, gas-free and suitable for technical cabinets and offices. Check that it matches your current battery in dimensions, terminals and hold-down: this reference has FASTON-6.35 terminals.

Technology inside the Fulbat FP6-12

Within the Fulbat catalogue, the FP6-12 is the 12 Ah model designed for this application.

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.

Fulbat: the maker behind the FP6-12

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.

Official warranty

The Fulbat FP6-12 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.

Care and maintenance

Replace all the batteries in the set at once and avoid environments continuously above 25 °C. Charge with a charger that has an AGM mode: it limits the voltage and protects the glass-fibre separators.

Delivery times 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

How is the Fulbat FP6-12 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 (−) 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.

How many years does this battery last?

Expected lifespan of the Fulbat FP6-12 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 FP6-12 battery?

Dimensions (length × width × height) are 151×51×100 mm — also written as 151x51x100 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.

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 devices. See the "Equivalents" section to view recommended options at the same performance level.
