What the Fulbat FP12-40FR is for
With 40 Ah, the Fulbat FP12-40FR 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.
Dimensions, polarity and mounting
It has external dimensions of 197 × 165 × 170 mm. 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.
Technology inside the Fulbat FP12-40FR
Fulbat builds the FP12-40FR 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. All the Fulbat batteries in our catalogue are genuine product, recently manufactured and covered by the manufacturer's warranty.
Warranty and coverage
The Fulbat FP12-40FR 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.
Usage and maintenance tips
Charge with a charger that has an AGM mode: it limits the voltage and protects the glass-fibre separators. Replace all the batteries in the set at once and avoid environments continuously above 25 °C.
Delivery times and returns
Order before 6:00 pm with stock available and it leaves today: mainland Spain and Portugal receive it in 24-48 working hours, the islands and the rest of the EU in 3 to 5 days.

Frequently asked questions
Is the Fulbat FP12-40FR an AGM battery and what are the benefits of AGM?
Yes. The FP12-40FR from Fulbat uses AGM (Absorbent Glass Mat) technology: a sealed lead-acid battery where the electrolyte is absorbed in a glass-fibre mat. It withstands more charge/discharge cycles than a conventional one, handles heat better and is the required technology for devices with advanced Start-Stop and regenerative braking. Expected lifespan: 5-8 years under normal conditions.
What are the measurements of the FP12-40FR 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.
