## Description

## Stationary battery Fulbat FP12-18FR 18Ah 12V

12*V* Voltage
18*Ah* Capacity

The **12 V**, **18 Ah** **Fulbat FP12-18FR** stationary battery with AGM technology is designed for UPS, alarms, telecoms and emergency lighting. Measuring 181 × 76 × 167 mm, it is the direct replacement for UPS, alarm and emergency systems fitted from the factory with a 18 Ah battery of this format.
- AGM: faster recharging and better cycle resistance than a conventional battery.
- Instant response to mains failures.
- Low self-discharge and high reliability.
- Standard format for UPS and emergency systems.

### What the Fulbat FP12-18FR is for

The Fulbat FP12-18FR 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 BOLT-M8 terminals.

### Will it fit your current battery tray?

In terms of format, the Fulbat FP12-18FR measures 181 × 76 × 167 mm (length × width × height). It uses BOLT-M8 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.

### Technology inside the Fulbat FP12-18FR

Fulbat builds the FP12-18FR to the same standards as the rest of its catalogue; what changes between references is capacity, format and terminal position.
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.

### Why choose Fulbat batteries

Fulbat has manufactured in France since 1978 and specialises in motorcycles and light vehicles. Its catalogue is short and clear, covers almost the whole fleet and works only with sealed, leak-free batteries. At baterias.com we work directly with the manufacturer or its official distributor: real stock, brand-new product and official warranty.

### Manufacturer's warranty

The Fulbat FP12-18FR 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.

### How to make it last longer

Check the float voltage of the UPS or charger: a voltage that is too high shortens the life of a sealed battery. Charge with a charger that has an AGM mode: it limits the voltage and protects the glass-fibre separators.

### Delivery times and returns

Orders placed **before [[ks:cutoff]]** with the battery in stock ship the same day. Delivery in mainland Spain and Portugal takes 24-48 working hours; for the Balearic Islands and the rest of the European Union allow 3 to 5 working days. You have **[[ks:return_days]] days** to return an unused battery; in mainland Spain and Portugal collection is free. We email you the tracking number as soon as the parcel ships.

## Frequently asked questions

### How is the Fulbat FP12-18FR 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 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.

### What is the service life of the FP12-18FR model?

Expected lifespan of the Fulbat FP12-18FR 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 FP12-18FR model?

Dimensions (length × width × height) are 182×77×168 mm — also written as 182x77x168 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.
