Exide ETX9-BS · Motorcycle battery 12V 8Ah 120A AGM

Motorcycle battery Exide ETX9-BS Moto AGM 8Ah 120A 12V

With 8 Ah at 12 V and 120 A of cold cranking current (EN), the Exide ETX9-BS with AGM technology replaces the original battery of motorcycles, scooters, quads and personal watercraft. It measures 150 × 90 × 105 mm and the positive terminal on the left, the format sought by anyone replacing a 8 Ah battery in motorcycles.

In short: the Exide ETX9-BS (8 Ah, 120 A, 150 × 90 × 105 mm, positive terminal on the left). Verified equivalent alternatives: Exide AGM12-7.5 and Varta YTX9-BS.

• 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 Exide ETX9-BS is for

The Exide ETX9-BS 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 3.10 kg, M12 terminals and B0 hold-down.

Will it fit your current battery tray?

In terms of format, the Exide ETX9-BS measures 150 × 90 × 105 mm (length × width × height) and weighs 3.10 kg. The positive terminal on the left decides which side the cables end up on: it is the detail that causes most buying mistakes, so check it before ordering. It uses a B0 hold-down and M12 terminals, the system that anchors and connects it in the vehicle. 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 Exide ETX9-BS: Moto AGM range and AGM technology

The ETX9-BS is part of the Exide Moto AGM range. Choosing the right reference within the series comes down to capacity, dimensions and terminals: technology and quality are common to the whole family.

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 Exide does differently

With more than a century of history, Exide Technologies manufactures automotive, marine, motorcycle and industrial batteries in Europe. Its presence as original equipment on assembly lines vouches for the quality of every reference. We guarantee that every Exide arrives new, charged and with the manufacturer's full warranty.

Official warranty

The Exide ETX9-BS 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. Check the resting voltage before the season (above 12.6 V on a charged battery) and make sure the terminals are clean and tight.
