Stationary battery Fulbat FP6-2.8 2.8Ah 6V

6VVoltage
2.8AhCapacity

Designed for UPS, alarms, telecoms and emergency lighting, the Fulbat FP6-2.8 offers 2.8 Ah with AGM technology on permanent float charge. Measuring 66 × 33 × 103 mm, it is the direct replacement for UPS, alarm and emergency systems fitted from the factory with a 2.8 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 FP6-2.8

In terms of format, the Fulbat FP6-2.8 measures 66 × 33 × 103 mm (length × width × height). It uses FASTON-4.8 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.

What the Fulbat FP6-2.8 is for

Designed for UPS, alarms, telecoms and emergency lighting, the Fulbat FP6-2.8 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-4.8 terminals.

Technology inside the Fulbat FP6-2.8

The FP6-2.8 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.

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.

Fulbat: the maker behind the FP6-2.8

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 FP6-2.8 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.

Usage and maintenance tips

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.

When you get it and how to return it

Same-day dispatch from our warehouse for in-stock orders placed before 6:00 pm: 24-48 working hours in mainland Spain and Portugal, 3 to 5 days in the islands and the rest of Europe. Returns are accepted for 14 days if the battery has not been used (free collection on the Iberian mainland). You will receive tracking by email.

Frequently asked questions

How is the Fulbat FP6-2.8 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.

What is the service life of the FP6-2.8 model?

Expected lifespan of the Fulbat FP6-2.8 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 FP6-2.8 model?

Dimensions (length × width × height) are 66×33×103 mm — also written as 66x33x103 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 batteries are equivalent to the Fulbat FP6-2.8?

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.
