The Motobatt MB5.5U in practice

MB5.5U vs Motobatt MB7BB

The Motobatt MB5.5U offers 7 Ah and 90 A cold cranking in a 135 × 60 × 130 mm case. The Motobatt MB7BB, same brand and technology, goes up to 9 Ah and 150 A with 15 mm more length The difference shows on diesels and in hard winters; for a daily-driven petrol car the extra is not needed.

The Motobatt MB5.5U from the Quadflex range is a motorcycle battery with 7 Ah and 90 A of cold cranking current (EN), designed for motorcycles, scooters, quads and personal watercraft. It replaces the original battery without adaptation in motorcycles with a 135 × 60 × 130 mm format: same 7 Ah capacity.

  • AGM technology: absorbed electrolyte, no spills, can be mounted at an angle.
  • Same JIS code as the original battery: fits first time.
  • Resistant to the vibration typical of two wheels.
  • Energetic cranking for high-compression engines.

What the Motobatt MB5.5U is for

The Motobatt MB5.5U 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 2.48 kg.

Size, terminals and hold-down of the Motobatt MB5.5U

It has external dimensions of 135 × 60 × 130 mm and weighs 2.48 kg. Checking the three dimensions and the terminal position before buying avoids the most common mistake when replacing a battery.

The Motobatt MB5.5U: Quadflex range and AGM technology

Within the Motobatt catalogue, the Quadflex series groups the references designed for this use. The MB5.5U is the 7 Ah model of that family, with the same performance as its siblings in other sizes.

AGM (Absorbent Glass Mat) technology seals the electrolyte in glass microfibre. The result is a maintenance-free battery that is highly vibration-resistant and able to withstand deep discharges that would ruin a classic lead-acid battery.

Why choose Motobatt batteries

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. All the Motobatt batteries in our catalogue are genuine product, recently manufactured and covered by the manufacturer's warranty.

Manufacturer's warranty

The Motobatt MB5.5U 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.

Usage and maintenance tips

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. If the bike spends the winter standing, connect a trickle charger: deep discharge through inactivity is the first cause of premature failure.

Shipping, delivery and returns

Same-day dispatch from our warehouse for in-stock orders placed before 6:00 pm: 1 to 2 working days in mainland Spain and 1 to 3 working days in mainland Portugal, 1 to 5 days in the islands and the rest of Europe.

Frequently asked questions

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 7 Ah. High-current car chargers can damage it. If the bike is laid up for the winter, keep it on a maintenance charger.

How long does the Motobatt MB5.5U battery last?

There is no exact figure: for a battery such as the Motobatt MB5.5U, a reasonable guide is 3 to 5 years, keeping it charged when the bike is not in use. Many factors play a part: how it is used (lots of short trips, for example), temperature (cold makes every start harder and intense heat evaporates the electrolyte), the condition of the alternator and charging system, power drawn with the engine off and maintenance.

What are the measurements of the MB5.5U model?

It measures 135×60×130 mm in length × width × height, with the terminals included in the height. Measure the battery tray before ordering: a one-millimetre difference is enough for the hold-down clamp not to close.

Will the Motobatt MB5.5U battery fit my motorcycle?

For your own vehicle: type your number plate into the finder (DGT/DVLA/KBA identify model and engine), check the "Compatible vehicles" tab below, listing vehicles verified by our technical team, or message us on WhatsApp with make, model, engine and year; we 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.

What are the equivalents of the MB5.5U model?

A direct equivalent needs what this MB5.5U offers: 135×60×130 mm, the same Ah and CCA. The "Equivalents" section of this page gathers the recommended options with equivalent performance.
