  • Resistant to garden-engine vibration.
  • Sealed and maintenance-free.
  • Direct replacement for the original battery.

What the Fulbat FL-RM02 is for

Designed for ride-on mowers, tillers and garden machinery, the Fulbat FL-RM02 is a compact, maintenance-free replacement.

Technology inside the Fulbat FL-RM02

Fulbat builds the FL-RM02 to the same standards as the rest of its catalogue; what changes between references is capacity, format and terminal position.

A LiFePO4 battery starts with the same nominal voltage as a lead-acid one but with far less weight and a service life several times longer. It requires a lithium-compatible charger.

Dimensions, polarity and mounting

It has external dimensions of 212 × 164 × 108 mm. Before replacing it, measure your current battery tray: if all three dimensions and the terminal positions match, the swap is direct and needs no adapters.

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

Usage and maintenance tips

Store the battery at 50-70% charge if it will be unused for months. Check the voltage before the first start of the season and clean the terminals.

Warranty and coverage

The Fulbat FL-RM02 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.

Shipping, delivery 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. You have 14 days to return it if it has not been installed, with free collection on the mainland, and shipment tracking by email.

Frequently asked questions

How is the Fulbat FL-RM02 battery installed in the vehicle?

In most trucks 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 our blog. 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 trucks with Start-Stop or BMS, register the battery via OBD so the alternator applies the correct charging profile.

How long does the Fulbat FL-RM02 battery last?

Expected lifespan of the Fulbat FL-RM02 is 10 to 15 years, equivalent to 3,000-5,000 cycles at 80% DoD. 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 FL-RM02 model?

Dimensions (length × width × height) are 212×164×108 mm — also written as 212x164x108 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-RM02 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 16:40–18:00 (Spanish time, CET)). The FL-RM02 typically fits a wide range of European vehicles thanks to its standard DIN case format.

Which batteries are equivalent to the Fulbat FL-RM02?

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.
