Fulbat FLTX20HL 12Ah 720A is a quality battery with official manufacturer warranty, confirmed stock and 24-48 h delivery across the peninsula.

The Fulbat FLTX20HL lithium battery offers V and 720 A of cold cranking current (EN) in an ultra-light format designed for motorcycles and quads looking to save weight and gain cranking power. Measuring 175 × 87 × 155 mm and the positive terminal on the right, it is the direct replacement for motorcycles fitted from the factory with a 12 Ah battery of this format.
The Fulbat FLTX20HL is made in the 175 × 87 × 155 mm format and weighs 2.30 kg. The positive terminal on the right decides which side the cables end up on: it is the detail that causes most buying mistakes, so check it before ordering. 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.
With its reduced weight, the Fulbat FLTX20HL is a popular upgrade on sport, off-road and restored classic bikes looking to shed kilos. Check that it matches your current battery in dimensions, terminals and hold-down: this reference has a weight of 2.30 kg.
Within the Fulbat catalogue, the FLTX20HL is the 12 Ah model designed for this application.
LiFePO4 chemistry is the safest of the lithium batteries: thermally stable, cobalt-free and good for thousands of cycles, protected by its electronic management system.
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.
The Fulbat FLTX20HL comes with the manufacturer's official warranty. Always charge with a LiFePO4-compatible charger: a lead-acid charger with a desulphation phase can damage it and void the warranty.
Check that the bike's regulator does not exceed 14.6 V; if the vehicle stands for long periods, an occasional maintenance charge is enough. Always use a LiFePO4-compatible charger and avoid the desulphation modes of lead-acid chargers.
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.

Step-by-step guide to replace your car battery in 15-30 minutes (longer if the battery is under the seat or in the boot) without losing vehicle settings.
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.
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.
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.
Repeat with the positive cable (red, marked +). Important: never let a terminal touch metal of the car while the other is still connected.
Loosen the bottom hold-down clamp with the same wrench. Lift the battery carefully (it can weigh 15-25 kg). Clean the tray with a brush and baking soda if there is corrosion.
Place the battery in the same orientation as the old one (positive terminal on the same side). Tighten the hold-down clamp firmly.
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.
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.
In most cars 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 cars with Start-Stop or BMS, register the battery via OBD so the alternator applies the correct charging profile.
Expected lifespan of the Fulbat FLTX20HL 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.
Dimensions (length × width × height) are 175×87×155 mm — also written as 175x87x155 mm — following the European DIN standard. Always measure the space in your car before buying: even one extra millimetre can prevent the hold-down clamp from closing. The height shown includes the terminals.
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 cars. See the "Equivalents" section to view recommended options at the same performance level.
