## Description

12*V* Voltage
260*Ah* Capacity

Designed for UPS, alarms, telecoms and emergency lighting, the **Fulbat FP12-250** offers **260 Ah** with AGM technology on permanent float charge. Measuring 522 × 268 × 226 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 260 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.

### Will it fit your current battery tray?

It has external dimensions of 522 × 268 × 226 mm. 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 BOLT-M6 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 FP12-250 is for

With 260 Ah, the Fulbat FP12-250 gives your UPS or emergency system the autonomy it needs. Replace all the batteries in the set at once. Check that it matches your current battery in dimensions, terminals and hold-down: this reference has BOLT-M6 terminals.

### Technology inside the Fulbat FP12-250

The FP12-250 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.

### 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. We guarantee that every Fulbat arrives new, charged and with the manufacturer's full warranty.

### Official warranty

The Fulbat FP12-250 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. Replace all the batteries in the set at once and avoid environments continuously above 25 °C.

### 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 is the Fulbat FP12-250 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 FP12-250 model?

Expected lifespan of the Fulbat FP12-250 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 size is this battery?

Dimensions (length × width × height) are 522×268×226 mm — also written as 522x268x226 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 FP12-250 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.
