Stationary battery Fulbat FP12-40 40Ah 12V

12VVoltage
40AhCapacity

Designed for UPS, alarms, telecoms and emergency lighting, the Fulbat FP12-40 offers 40 Ah with AGM technology on permanent float charge. Its 197 × 165 × 170 mm make it the exact replacement for the 40 Ah battery fitted as standard to many UPS, alarm and emergency systems.

  • Standard format for UPS and emergency systems.
  • Low self-discharge and high reliability.
  • Instant response to mains failures.
  • AGM: faster recharging and better cycle resistance than a conventional battery.

What the Fulbat FP12-40 is for

With 40 Ah, the Fulbat FP12-40 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.

Size, terminals and hold-down of the Fulbat FP12-40

The Fulbat FP12-40 is made in the 197 × 165 × 170 mm format. 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 Fulbat does differently

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. All the Fulbat batteries in our catalogue are genuine product, recently manufactured and covered by the manufacturer's warranty.

Technology inside the Fulbat FP12-40

Fulbat builds the FP12-40 to the same standards as the rest of its catalogue; what changes between references is capacity, format and terminal position.

AGM means the acid is held in a glass mat instead of floating free. That is why the battery can be installed in the cabin without gases, survives more cycles and recovers its charge quickly.

Usage and maintenance tips

Replace all the batteries in the set at once and avoid environments continuously above 25 °C. Check the float voltage of the UPS or charger: a voltage that is too high shortens the life of a sealed battery.

Manufacturer's warranty

The Fulbat FP12-40 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.

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.

⏱ 10-15 min🛠 Tools: Screwdriver or small wrench (3-5 mm typical) · Protective gloves
  1. 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.

  2. 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.

  3. Step 3. Disconnect the negative (−) first

    With insulated gloves, remove the negative (−) cable first. Some UPS have protection fuses — note their position before removing.

  4. 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.

  5. 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.

  6. 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.

  7. 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.

  8. 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 fit the FP12-40 model in my device?

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 FP12-40 battery last?

Expected lifespan of the Fulbat FP12-40 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 FP12-40 model?

Dimensions (length × width × height) are 197×165×170 mm — also written as 197x165x170 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.
