Motorcycle battery Exide AGM12-8 YTZ10S Moto AGM 8.6Ah 145A 12V
With 8.6 Ah at 12 V and 145 A of cold cranking current (EN), the Exide AGM12-8 with AGM technology replaces the original battery of motorcycles, scooters, quads and personal watercraft. It replaces the original battery without adaptation in motorcycles with a 150 × 90 × 95 mm format: same 8.6 Ah capacity and the positive terminal on the left.
In short: the Exide AGM12-8 (8 Ah, 145 A, 150 × 90 × 95 mm, positive terminal on the left). Verified equivalent alternatives: Exide ETZ10-BS and Varta YTX7A-BS.
- 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 Exide AGM12-8 is for
The Exide AGM12-8 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 3.40 kg, M12 terminals and B0 hold-down.
Size, terminals and hold-down of the Exide AGM12-8
It has external dimensions of 150 × 90 × 95 mm and weighs 3.40 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 AGM12-8: Moto AGM range and AGM technology
The AGM12-8 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.
Why choose Exide batteries
Exide is one of the world's largest battery manufacturers and an original-equipment supplier to many car makers. Its European plants produce starter, industrial and leisure batteries under original-equipment quality controls. All the Exide batteries in our catalogue are genuine product, recently manufactured and covered by the manufacturer's warranty.
Warranty and coverage
The Exide AGM12-8 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
Check the resting voltage before the season (above 12.6 V on a charged battery) and make sure the terminals are clean and tight. 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
Order before 6:00 pm with stock available and it leaves today: mainland Spain and Portugal receive it in 24-48 working hours, the islands and the rest of the EU in 3 to 5 days.

Frequently asked questions
Is the YTX7A-BS model AGM? What does this technology offer?
Yes. AGM (Absorbent Glass Mat) technology, 8.6 Ah and 12 V: sealed lead-acid, with the electrolyte held in glass fibre. Compared with a conventional battery it withstands more charge/discharge cycles and handles heat better.
How should this motorcycle battery be charged?
With a 12 V motorcycle charger delivering at most 10 % of its capacity: 0.9 A for its 8.6 Ah. High-current car chargers can damage it. If the bike is laid up for the winter, keep it on a maintenance charger.
Does it need maintenance?
No: being AGM, it is sealed and nothing needs topping up. Just keep it charged if the bike stands for a long time.
How long does the Exide YTX7A-BS battery last?
Estimated lifespan of the Exide YTX7A-BS: 4 to 6 years, keeping it charged when the bike is not in use. Treat it as an approximate guide, as every case is different. What weighs most: temperature (cold makes starts harder and intense heat evaporates the electrolyte), frequent short trips, the condition of the alternator and charging system, power draw while parked and maintenance.
What size is this battery?
Check the room available in your motorcycle, because a single millimetre too much can stop the clamp from closing. Its dimensions are 150×90×95 mm, also written 150x90x95 mm; the height already includes the terminals.
What polarity does the Exide YTX7A-BS battery have?
The YTX7A-BS has the positive on the left: that is its polarity. It must match your current battery: reversed polarity means lengthening cables or reconfiguring the system, with a risk of short circuit. Face the battery with its terminals nearest you and see which side the positive post (+, red ring) is on.
Is the YTX7A-BS valid for my vehicle?
Three routes: the "Compatible vehicles" tab on this page, with the vehicles verified by our technical team; your number plate in the finder, from which DGT/DVLA/KBA detect model and engine; and WhatsApp, with make, model, engine and year, during business hours (Mon–Fri 10:00–13:30 and 16:30–18:00 (Spanish time, CET)). Always cross-check with what the motorcycle manufacturer states in the owner's handbook.
Which batteries are equivalent to the Exide YTX7A-BS?
The options at the same level are in the "Equivalents" section of this page. A battery interchangeable with the Exide YTX7A-BS must match it on dimensions (150×90×95 mm), polarity (positive on the left), capacity (8.6 Ah) and cranking current (145 A).
Exide AGM12-8 or Exide ETZ10-BS: which one to choose?
Same family as the AGM12-8, one step up in performance. Compared with the AGM12-8 it has 1 Ah more. It costs 14,10 € less. Worth it on big-displacement bikes, with lots of electrical equipment or that sleep in the cold; on an average bike the AGM12-8 does the job.
Exide AGM12-8 or Varta YTX7A-BS: which one to choose?
It is the verified Varta equivalent for the AGM12-8 tray. Compared with the AGM12-8 it has 2 Ah less and 40 A of cold cranking less. It costs 14,90 € less. Decide by price, brand preference and availability: both fit and crank the same.
