Motorcycle battery Motobatt 12N7-3B Quadflex 11Ah 140A 12V

The Motobatt 12N7-3B from the Quadflex range is a motorcycle battery with 11 Ah and 140 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 136 × 76 × 133 mm format: same 11 Ah capacity.

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

What the Motobatt 12N7-3B is for

Designed for motorcycles, scooters, quads and personal watercraft, the Motobatt 12N7-3B replaces the original battery of bikes that use this code or format. Check the position of the positive terminal before ordering. Check that it matches your current battery in dimensions, terminals and hold-down: this reference has a weight of 3.35 kg.

Will it fit your current battery tray?

The Motobatt 12N7-3B is made in the 136 × 76 × 133 mm format and weighs 3.35 kg. Checking the three dimensions and the terminal position before buying avoids the most common mistake when replacing a battery.

The Motobatt 12N7-3B: Quadflex range and AGM technology

The 12N7-3B is part of the Motobatt Quadflex range. Choosing the right reference within the series comes down to capacity, dimensions and terminals: technology and quality are common to the whole family.

In an AGM battery the electrolyte is absorbed in glass-fibre separators: there is no free liquid, it cannot spill and it can be mounted at an angle. That construction lowers internal resistance, speeds up recharging and multiplies cycle life compared with a conventional battery.

Motobatt: the maker behind the 12N7-3B

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. At baterias.com we work directly with the manufacturer or its official distributor: real stock, brand-new product and official warranty.

Manufacturer's warranty

The Motobatt 12N7-3B 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

Same-day dispatch from our warehouse for in-stock orders placed before 6:00 pm: 24-48 working hours in mainland Spain and Portugal, 3 to 5 days in the islands and the rest of Europe. Returns are accepted for 14 days if the battery has not been used (free collection on the Iberian mainland). You will receive tracking by email.
