Motorcycle battery Exide ET9B-BS Moto AGM 8Ah 110A 12V
With 8 Ah at 12 V and 110 A of cold cranking current (EN), the Exide ET9B-BS with AGM technology replaces the original battery of motorcycles, scooters, quads and personal watercraft. Measuring 150 × 70 × 105 mm and the positive terminal on the left, it is the direct replacement for motorcycles fitted from the factory with a 8 Ah battery of this format.
- Holds its charge through winter storage.
- Compact and lightweight format.
- AGM: faster recharging and better cycle resistance than a conventional battery.
- Sealed and ready to fit, no acid handling.
Will it fit your current battery tray?
The Exide ET9B-BS is made in the 150 × 70 × 105 mm format and weighs 2.90 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 M04 terminals, the system that anchors and connects it in the vehicle. 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.
What the Exide ET9B-BS is for
The Exide ET9B-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 2.90 kg, M04 terminals and B0 hold-down.
The Exide ET9B-BS: Moto AGM range and AGM technology
The ET9B-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.
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.
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.
Warranty and coverage
The Exide ET9B-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.
How to make it last longer
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.
When you get it and how to return it
Orders placed before 6:00 pm with the battery in stock ship the same day. Delivery in mainland Spain and Portugal takes 24-48 working hours; for the Balearic Islands and the rest of the European Union allow 3 to 5 working days. You have 14 days to return an unused battery; in mainland Spain and Portugal collection is free. We email you the tracking number as soon as the parcel ships.

Frequently asked questions
Is the Exide ET9B-BS an AGM battery and what are the benefits of AGM?
Yes. The ET9B-BS from Exide uses AGM (Absorbent Glass Mat) technology: a sealed lead-acid battery where the electrolyte is absorbed in a glass-fibre mat. It withstands more charge/discharge cycles than a conventional one, handles heat better and is the required technology for motorcycles with advanced Start-Stop and regenerative braking. Expected lifespan: 5-8 years under normal conditions.
How is the Exide ET9B-BS battery installed in the vehicle?
In most motorcycles it fits in 15-30 minutes with a 10 mm wrench; if the battery is under the seat or in the boot the time can double. See the step-by-step guide on our blog. Quick summary: 1) switch off the engine and remove the key; 2) locate the original battery (engine bay, boot or under seat); 3) disconnect the negative (−) terminal first, then the positive (+); 4) loosen the hold-down clamp and remove the old battery; 5) fit the new one in the same orientation — with positive on the left match the polarity shown on the product sheet; 6) connect the positive (+) first, then the negative (−). On motorcycles with Start-Stop or BMS, register the battery via OBD so the alternator applies the correct charging profile.
What is the service life of the ET9B-BS model?
Expected lifespan of the Exide ET9B-BS is 5 to 8 years in mild-climate motorcycle use with Start-Stop. In cold regions it drops slightly due to cold-start stress; in very hot regions it also drops because of electrolyte evaporation. To extend its life: avoid deep discharges (headlights on with engine off), have the alternator checked yearly, and keep the battery clean and properly secured.
What are the dimensions of the Exide ET9B-BS battery?
Dimensions (length × width × height) are 150×70×105 mm — also written as 150x70x105 mm — following the European DIN standard. Always measure the space in your motorcycle before buying: even one extra millimetre can prevent the hold-down clamp from closing. The height shown includes the terminals.
What polarity does the Exide ET9B-BS battery have?
Polarity: positive on the left. To identify it, place the battery in front of you with the terminals facing you and check which side the positive (+, marked with a red ring) is on. Before buying, verify the polarity matches your current battery: switching polarity forces longer cables or system reconfiguration, with short-circuit risk.
Will the Exide ET9B-BS battery fit my motorcycle?
Three options to confirm: 1) enter your number plate in the finder (DGT/DVLA/KBA auto-detect your model and engine); 2) check the "Compatible vehicles" tab on this page, where we list every vehicle verified by our technical team; 3) if you cannot find your model, message us on WhatsApp with brand, model, engine and year — we reply during business hours (Mon–Fri 10:00–13:30 and 16:40–18:00 (Spanish time, CET)). The ET9B-BS typically fits a wide range of European vehicles thanks to its standard DIN case format.
Which batteries are equivalent to the Exide ET9B-BS?
Directly interchangeable batteries (same dimensions, same polarity, same Ah and CCA) are the OEM equivalents from leading brands: Bosch, Tudor, Exide and, depending on the model, Banner or Yuasa. Exact equivalence depends on technology — an EFB cannot be replaced with a conventional battery in Start-Stop motorcycles. See the "Equivalents" section to view recommended options at the same performance level.
