With 6.5 Ah at 12 V and 85 A of cold cranking current (EN), the Motobatt MTX6.5L with GEL technology replaces the original battery of motorcycles, scooters, quads and personal watercraft. Measuring 138 × 66 × 102 mm, it is the direct replacement for motorcycles fitted from the factory with a 6.5 Ah battery of this format.
- GEL: excellent resistance to deep discharge and long cycle life.
- Sealed and ready to fit, no acid handling.
- Holds its charge through winter storage.
- Compact and lightweight format.
What the Motobatt MTX6.5L is for
The Motobatt MTX6.5L is a common replacement in motorcycles, scooters, quads and personal watercraft. If your bike spends the winter standing, a trickle charger stops it reaching spring flat. Check that it matches your current battery in dimensions, terminals and hold-down: this reference has a weight of 2.17 kg.
Will it fit your current battery tray?
It has external dimensions of 138 × 66 × 102 mm and weighs 2.17 kg. 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.
The Motobatt MTX6.5L: Super GEL range and GEL technology
Within the Motobatt catalogue, the Super GEL series groups the references designed for this use. The MTX6.5L is the 6.5 Ah model of that family, with the same performance as its siblings in other sizes.
GEL technology fixes the acid in a solid gel. That removes maintenance and leaks and gives very long cycle life, in exchange for slightly slower recharging and lower peak current than an AGM.
What Motobatt does differently
Motobatt batteries stand out for capacity and cranking current above the original battery in the same tray, thanks to a compact AGM design and the four-terminal Quadflex system. We guarantee that every Motobatt arrives new, charged and with the manufacturer's full warranty.
Official warranty
The Motobatt MTX6.5L comes with the manufacturer's official warranty. The warranty does not cover discharge through prolonged inactivity: if the bike stands for months, use a trickle charger.
Care and maintenance
If the bike spends the winter standing, connect a trickle charger: deep discharge through inactivity is the first cause of premature failure. Avoid repeated cranking attempts on a cold bike for long: if it does not start on the third try, let the battery rest for a minute.
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. You have 14 days to return it if it has not been installed, with free collection on the mainland, and shipment tracking by email.

How to change the battery
Guide to replace your motorcycle battery in 10-15 minutes. Motorcycle batteries are light (2-5 kg) and usually need an 8 mm wrench.
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 compartment
On motorcycles it is usually under the seat, in the rear cowl or behind a side panel. Check the manual — access varies a lot between models.
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
Loosen the hold-down clamp or the straps that secure it. Lift the battery carefully — typical weight 2-5 kg. Check the terminals are not corroded before fitting the new one.
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
Is the Motobatt MTX6.5L a GEL battery? What is GEL used for?
Yes, this model is a GEL battery: sealed lead-acid where the electrolyte is in gel form. It tolerates deep discharges very well and is ideal for cyclic use (solar, motorhomes, electric wheelchairs, motorcycles). Requires a GEL-specific smart charger — max charge voltage ~14.1 V (vs 14.4-14.7 V for AGM). Lifespan 6-10 years.
How is the Motobatt MTX6.5L battery installed in the vehicle?
In most motorcycles 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 motorcycles with Start-Stop or BMS, register the battery via OBD so the alternator applies the correct charging profile.
How long does the Motobatt MTX6.5L battery last?
Expected lifespan of the Motobatt MTX6.5L is 6 to 10 years in cyclic use (marine, caravan, solar) with controlled discharges. 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 MTX6.5L model?
Dimensions (length × width × height) are 138×66×102 mm — also written as 138x66x102 mm — following the European DIN standard. Always measure the space in your motorcycle before buying: even one extra millimetre can prevent the hold-down clamp from closing. The height shown includes the terminals.
Will the Motobatt MTX6.5L battery fit my motorcycle?
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 MTX6.5L typically fits a wide range of European vehicles thanks to its standard DIN case format.
Which batteries are equivalent to the Motobatt MTX6.5L?
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 motorcycles. See the "Equivalents" section to view recommended options at the same performance level.
