Lawn mower battery Fulbat FL-HU04 5.2Ah 18V
With 5.2 Ah, the Fulbat FL-HU04 starts ride-on mowers, tillers and garden machinery after months of storage. It replaces the original battery without adaptation in ride-on mowers with a 146 × 67 × 38 mm format: same 5.2 Ah capacity.
- Compact format for small trays.
- Reliable starting after months of winter storage.
- Resistant to garden-engine vibration.
- Direct replacement for the original battery.
What the Fulbat FL-HU04 is for
The Fulbat FL-HU04 is designed for ride-on mowers, tillers and garden machinery. After winter, a full charge before the first start avoids surprises.
Dimensions, polarity and mounting
It has external dimensions of 146 × 67 × 38 mm. 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 FL-HU04
Fulbat builds the FL-HU04 to the same standards as the rest of its catalogue; what changes between references is capacity, format and terminal position.
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. We guarantee that every Fulbat arrives new, charged and with the manufacturer's full warranty.
Warranty and coverage
The Fulbat FL-HU04 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 voltage before the first start of the season and clean the terminals. Disconnect or remove the battery over winter and give it a maintenance charge before storing it.
Delivery times and returns
Same-day dispatch from our warehouse for in-stock orders placed before 6:00 pm: 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 14 days if the battery has not been used (free collection on the Iberian mainland). You will receive tracking by email.

Frequently asked questions
How long does the Fulbat FL-HU04 battery last?
Expected lifespan of the Fulbat FL-HU04 is 8 to 10 years in lorry use. 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 dimensions of the Fulbat FL-HU04 battery?
Dimensions (length × width × height) are 146×68×39 mm — also written as 146x68x39 mm — following the European DIN standard. Always measure the space in your truck before buying: even one extra millimetre can prevent the hold-down clamp from closing. The height shown includes the terminals.
Is the FL-HU04 valid for my vehicle?
Three options to confirm: 1) enter your number plate in the finder (DGT/DVLA/KBA auto-detect your model and engine); 2) check the "Compatible vehicles" tab on this page, where we list every vehicle verified by our technical team; 3) if you cannot find your model, message us on WhatsApp with brand, model, engine and year — we reply during business hours (Mon–Fri 10:00–13:30 and 16:30–18:00 (Spanish time, CET)). The FL-HU04 typically fits a wide range of European vehicles thanks to its standard DIN case format.
What are the equivalents of the FL-HU04 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 trucks. See the "Equivalents" section to view recommended options at the same performance level.
