Fulbat FP12-4L · Stationary UPS battery 12V 4Ah AGM

Stationary battery Fulbat FP12-4L 4Ah 12V

The 12 V, 4 Ah Fulbat FP12-4L stationary battery with AGM technology is designed for UPS, alarms, telecoms and emergency lighting. Measuring 195 × 47 × 76 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 4 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.

What the Fulbat FP12-4L is for

With 4 Ah, the Fulbat FP12-4L 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 FASTON-4.8 terminals.

Size, terminals and hold-down of the Fulbat FP12-4L

The Fulbat FP12-4L is made in the 195 × 47 × 76 mm format. 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 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.

Technology inside the Fulbat FP12-4L

Fulbat builds the FP12-4L to the same standards as the rest of its catalogue; what changes between references is capacity, format and terminal position.

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. At baterias.com we work directly with the manufacturer or its official distributor: real stock, brand-new product and official warranty.

Official warranty

The Fulbat FP12-4L 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.

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.
