Designed for UPS, alarms, telecoms and emergency lighting, the Fulbat FP12-18 offers 18 Ah with AGM technology on permanent float charge. It measures 181 × 76 × 167 mm, the format sought by anyone replacing a 18 Ah battery in UPS, alarm and emergency systems.
- Maintenance-free for its whole service life.
- Sealed and gas-free: suitable for cabinets and offices.
- Long float life under permanent charge.
- AGM technology: absorbed electrolyte, no spills, can be mounted at an angle.
What the Fulbat FP12-18 is for
The Fulbat FP12-18 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?
The Fulbat FP12-18 is made in the 181 × 76 × 167 mm format. It uses BOLT-M8 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.
Technology inside the Fulbat FP12-18
Fulbat builds the FP12-18 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.
Fulbat: the maker behind the FP12-18
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. All the Fulbat batteries in our catalogue are genuine product, recently manufactured and covered by the manufacturer's warranty.
Manufacturer's warranty
The Fulbat FP12-18 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
Charge with a charger that has an AGM mode: it limits the voltage and protects the glass-fibre separators. Check the float voltage of the UPS or charger: a voltage that is too high shortens the life of a sealed battery.
When you get it and how to return it
Orders placed before 6:00 pm with the battery in stock ship the same day. Delivery in mainland Spain and Portugal takes 24-48 working hours; for the Balearic and Canary Islands and the rest of the European Union allow 3 to 5 working days. You have 14 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.

How to change the battery
Guide to replace a cyclic battery (12V 4-30Ah) for UPS, mobility scooter, alarm or backup device. Estimated time 10-15 minutes. Important: discharge residual voltage before handling.
Step 1. Power off and unplug the device
Unplug the device (UPS, scooter, alarm) and leave it off for at least 30 seconds to discharge residual capacitor voltage. Work on an insulating surface.
Step 2. Locate the battery compartment
Usually under the seat (mobility scooter/wheelchair), in the rear module of the UPS, or behind a side panel with screws. Check the device manual for unusual models.
Step 3. Disconnect the negative (−) first
With insulated gloves, remove the negative (−) cable first. Some UPS have protection fuses — note their position before removing.
Step 4. Disconnect the positive (+) terminal
Repeat with the positive cable (red, marked +). Important: never let a terminal touch metal of the car while the other is still connected.
Step 5. Remove the old battery
Typical weight 1-15 kg depending on capacity. Many cyclic batteries are AGM/GEL — keep them upright. Do NOT invert the battery: even sealed, residue may exist.
Step 6. Fit the new battery
Same orientation and type (AGM, GEL or flooded). Polarity must match the device, not a chassis (this is not a car). Make sure terminals do not touch metal parts of the compartment.
Step 7. Connect the positive (+) first
On cyclic devices the order is reversed compared to cars: positive (+) first, negative (−) afterwards. Tighten without forcing — the plastic terminal housing of cyclic batteries damages easily.
Step 8. Initial charge before first use
Cyclic batteries ship at 60-80%. Before first use, connect the device charger for 8-12 hours (or use an AGM/GEL smart charger if available). This avoids short cycles and extends lifespan.
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 FP12-18 battery last?
Expected lifespan of the Fulbat FP12-18 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 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.
What are the equivalents of the FP12-18 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.
