Stationary battery Fulbat FP12-2.9 2.9Ah 12V
The Fulbat FP12-2.9 with AGM technology is a 2.9 Ah, 12 V backup battery for UPS, alarms, telecoms and emergency lighting. Its 79 × 56 × 105 mm make it the exact replacement for the 2.9 Ah battery fitted as standard to many UPS, alarm and emergency systems.
- Instant response to mains failures.
- AGM: faster recharging and better cycle resistance than a conventional battery.
- Standard format for UPS and emergency systems.
- Low self-discharge and high reliability.
What the Fulbat FP12-2.9 is for
The Fulbat FP12-2.9 is designed for UPS, alarms, telecoms and emergency lighting: it sits on float charge and responds instantly to a mains failure. Check that it matches your current battery in dimensions, terminals and hold-down: this reference has FASTON-4.8 terminals.
Dimensions, polarity and mounting
The Fulbat FP12-2.9 is made in the 79 × 56 × 105 mm format. It uses FASTON-4.8 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.
Fulbat: the maker behind the FP12-2.9
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. We guarantee that every Fulbat arrives new, charged and with the manufacturer's full warranty.
Technology inside the Fulbat FP12-2.9
Fulbat builds the FP12-2.9 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.
Care and maintenance
Check the float voltage of the UPS or charger: a voltage that is too high shortens the life of a sealed battery. Replace all the batteries in the set at once and avoid environments continuously above 25 °C.
Official warranty
The Fulbat FP12-2.9 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
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
Is the Fulbat FP12-2.9 an AGM battery and what are the benefits of AGM?
Yes. The FP12-2.9 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 devices with advanced Start-Stop and regenerative braking. Expected lifespan: 5-8 years under normal conditions.
How is the Fulbat FP12-2.9 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 long does the Fulbat FP12-2.9 battery last?
Expected lifespan of the Fulbat FP12-2.9 is 5 to 8 years in mild-climate device use with Start-Stop. 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 FP12-2.9 model?
Dimensions (length × width × height) are 79×56×105 mm — also written as 79x56x105 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 FP12-2.9?
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.
