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.

## Frequently asked questions

### Is the Motobatt MTX6.5L a GEL battery? What is GEL used for?

Yes, GEL technology (6.5 Ah): a sealed lead-acid battery whose electrolyte is in gel form. Designed for cyclic use (solar installations, motorhomes, electric wheelchairs, motorcycles), it tolerates deep discharges very well. Charge it only with a GEL-specific smart charger; its voltage limit is below that of an AGM.

### How should this motorcycle battery be charged?

With a 12 V motorcycle charger delivering at most 10 % of its capacity: 0.7 A for its 6.5 Ah. High-current car chargers can damage it. If the bike is laid up for the winter, keep it on a maintenance charger.

### Does it need maintenance?

No: being GEL, it is sealed and nothing needs topping up. Just keep it charged if the bike stands for a long time.

### How long does the Motobatt MTX6.5L battery last?

As a guide, you can expect the Motobatt MTX6.5L to last 4 to 6 years, keeping it charged when the bike is not in use, although the real figure may be higher or lower. It can vary considerably with usage (short or long journeys), temperature, the condition of the alternator and charging system, power drawn with the engine off and maintenance. Cold demands more at every start and intense heat evaporates the electrolyte.

### What are the measurements of the MTX6.5L model?

Measure the battery tray before ordering: a one-millimetre difference is enough for the hold-down clamp not to close. It measures 138×66×102 mm in length × width × height, with the terminals included in the height.

### Will the Motobatt MTX6.5L battery fit my motorcycle?

Not sure? Try your number plate in the finder (DGT/DVLA/KBA detect model and engine) or the "Compatible vehicles" tab, checked by our technical team; if your motorcycle is not there, send us make, model, engine and year on WhatsApp and we will reply during business hours (Mon–Fri 10:00–13:30 and 16:30–18:00 (Spanish time, CET)). In every case, the motorcycle manufacturer's specifications (owner's handbook) take precedence.

### Which batteries are equivalent to the Motobatt MTX6.5L?

A battery interchangeable with the Motobatt MTX6.5L must match it on dimensions (138×66×102 mm), polarity, capacity (6.5 Ah) and cranking current (85 A). The options at the same level are in the "Equivalents" section of this page.

### Motobatt MTX6.5L or Fulbat FTX6,5L-BS GEL: which one to choose?

Same case and same technology as the MTX6.5L: an alternative by size, not an official equivalent. Compared with the MTX6.5L it has the same Ah and cranking power. It costs 19,15 € more. If the polarity matches and your bike had a similar capacity, it works as a replacement; if in doubt, ask us with your model.
