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.

How to change the battery
Guide to replace a truck battery in 30-60 minutes. Truck batteries weigh 25-50 kg — we recommend working in pairs and using a carrying strap.
Step 1. Prepare the vehicle
Park on a flat surface, switch off the engine and remove the key. Make sure all lights and electrical accessories are off. Wait 1-2 minutes before starting.
Step 2. Locate the battery
Open the bonnet. The battery is usually in the engine bay, but in many modern cars it may be in the boot or under the passenger seat. Check the manual if you cannot find it.
Step 3. Disconnect the negative (−) terminal
Use the 10 mm wrench to loosen the negative cable nut (black, marked −) and remove the cable from the post. Move it aside so it cannot touch any bodywork.
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 (two people)
Loosen the bottom hold-down clamp. Truck batteries weigh 25-50 kg — lift in pairs with gloves and a carrying strap. Forcing the lift alone risks back injury.
Step 6. Install the new battery
Place the battery in the same orientation as the old one (positive terminal on the same side). Tighten the hold-down clamp firmly.
Step 7. Connect the cables
Connect the positive (+) terminal first, then the negative (−). Tighten the nuts with the wrench until each terminal does not move. Apply anti-spark grease if you have any.
Step 8. Verify the engine starts
Close the bonnet. Start the engine to confirm everything works. On cars with Start-Stop or a BMS, you may need to register the battery via OBD so the alternator applies the correct charging profile.
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 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 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 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 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.
