## Description

## Stationary battery Fulbat FP12-9 9Ah 12V

12*V* Voltage
9*Ah* Capacity

The **Fulbat FP12-9** with AGM technology is a **9 Ah**, **12 V** backup battery for UPS, alarms, telecoms and emergency lighting. It replaces the original battery without adaptation in UPS, alarm and emergency systems with a 151 × 65 × 99 mm format: same 9 Ah capacity and the positive terminal on the right.
- Sealed and gas-free: suitable for cabinets and offices.
- Maintenance-free for its whole service life.
- AGM technology: absorbed electrolyte, no spills, can be mounted at an angle.
- Long float life under permanent charge.

### What the Fulbat FP12-9 is for

The Fulbat FP12-9 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-6.35 terminals.

### Dimensions, polarity and mounting

The Fulbat FP12-9 is made in the 151 × 65 × 99 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 FASTON-6.35 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 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. At baterias.com we work directly with the manufacturer or its official distributor: real stock, brand-new product and official warranty.

### Technology inside the Fulbat FP12-9

Within the Fulbat catalogue, the FP12-9 is the 9 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.

### 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.

### Manufacturer's warranty

The Fulbat FP12-9 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.

### Delivery times and returns

Same-day dispatch from our warehouse for in-stock orders placed **before [[ks:cutoff]]**: 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 **[[ks:return_days]] days** if the battery has not been used (free collection on the Iberian mainland). You will receive tracking by email.

## Frequently asked questions

### How do I change this battery step by step?

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 this page. 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 FP12-9 battery last?

Expected lifespan of the Fulbat FP12-9 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 FP12-9 battery?

Dimensions (length × width × height) are 151×65×100 mm — also written as 151x65x100 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.

### What are the equivalents of the FP12-9 model?

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.
