Motobatt MBT9B4 Quadflex · Motorcycle battery 9Ah 115A AGM

Motorcycle battery Motobatt YT9B4-YT9BBS Quadflex 9Ah 115A 12V

With 9 Ah at 12 V and 115 A of cold cranking current (EN), the Motobatt YT9B4-YT9BBS with AGM technology replaces the original battery of motorcycles, scooters, quads and personal watercraft. It measures 150 × 70 × 104 mm, the format sought by anyone replacing a 9 Ah battery in motorcycles.

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

What the Motobatt YT9B4-YT9BBS is for

Designed for motorcycles, scooters, quads and personal watercraft, the Motobatt YT9B4-YT9BBS 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 2.82 kg.

Dimensions, polarity and mounting

It has external dimensions of 150 × 70 × 104 mm and weighs 2.82 kg. 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.

The Motobatt YT9B4-YT9BBS: Quadflex range and AGM technology

Within the Motobatt catalogue, the Quadflex series groups the references designed for this use. The YT9B4-YT9BBS is the 9 Ah model of that family, with the same performance as its siblings in other sizes.

AGM means the acid is held in a glass mat instead of floating free. That is why the battery can be installed in the cabin without gases, survives more cycles and recovers its charge quickly.

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

Official warranty

The Motobatt YT9B4-YT9BBS 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.

How to make it last longer

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.

When you get it and how to return it

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.
