With **7 Ah** at **12 V** and **85 A** of cold cranking current (EN), the **Exide ET7B-BS** with AGM technology replaces the original battery of motorcycles, scooters, quads and personal watercraft. Measuring 150 × 65 × 95 mm and the positive terminal on the left, it is the direct replacement for motorcycles fitted from the factory with a 7 Ah battery of this format.
- AGM: faster recharging and better cycle resistance than a conventional battery.
- Sealed and ready to fit, no acid handling.
- Holds its charge through winter storage.
- Compact and lightweight format.

### What the Exide ET7B-BS is for

With 7 Ah, the Exide ET7B-BS covers the starting of motorcycles, scooters, quads and personal watercraft. The JIS code on your current battery label is the safest way to confirm equivalence. Check that it matches your current battery in dimensions, terminals and hold-down: this reference has a weight of 2.40 kg, M04 terminals and B0 hold-down.

### Size, terminals and hold-down of the Exide ET7B-BS

It has external dimensions of 150 × 65 × 95 mm and weighs 2.40 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 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 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. At baterias.com we work directly with the manufacturer or its official distributor: real stock, brand-new product and official warranty.

### The Exide ET7B-BS: Moto AGM range and AGM technology

The **Moto AGM** is the Exide range the ET7B-BS belongs to: it shares the same construction and quality criteria with the rest of the series, and varies in capacity and format to suit each vehicle.
AGM (Absorbent Glass Mat) technology seals the electrolyte in glass microfibre. The result is a maintenance-free battery that is highly vibration-resistant and able to withstand deep discharges that would ruin a classic lead-acid battery.

### 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. Charge with a charger that has an AGM mode: it limits the voltage and protects the glass-fibre separators.

### Warranty and coverage

The Exide ET7B-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.

### When you get it and how to return it

Same-day dispatch from our warehouse for in-stock orders placed **before 6:00 pm**: 1 to 2 working days in mainland Spain and 1 to 3 working days in mainland Portugal, 1 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.

## Frequently asked questions

### Is this battery AGM? What is it for?

Yes. The Exide YT7B-BS is AGM (Absorbent Glass Mat): sealed lead-acid, with the electrolyte absorbed in glass fibre. It tolerates heat better and handles more cycles than a conventional battery.

### How should this motorcycle battery be charged?

With a 12 V motorcycle charger delivering at most 10 % of its capacity: 0.7 A for its 7 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.

### What is the service life of the YT7B-BS model?

There is no exact figure: for a battery such as the Exide YT7B-BS (AGM), a reasonable guide is 4 to 6 years, keeping it charged when the bike is not in use. Many factors play a part: how it is used (lots of short trips, for example), temperature (cold makes every start harder and intense heat evaporates the electrolyte), the condition of the alternator and charging system, power drawn with the engine off and maintenance.

### What are the dimensions of the Exide YT7B-BS battery?

It measures 150×65×95 mm in length × width × height, with the terminals included in the height. Measure the battery tray before ordering: a one-millimetre difference is enough for the hold-down clamp not to close.

### Which side is the positive terminal on this battery?

It has the positive on the left (polarity). Put it in front of you, terminals towards you: the post with the red ring and the + sign is the positive. Compare it with the battery you are replacing: if it does not match, cables must be lengthened or the system reconfigured, with a risk of short circuit.

### Will the Exide YT7B-BS battery fit my motorcycle?

For your own vehicle: type your number plate into the finder (DGT/DVLA/KBA identify model and engine), check the "Compatible vehicles" tab below, listing vehicles verified by our technical team, or message us on WhatsApp with make, model, engine and year; we reply during business hours (Mon–Fri 10:00–13:30 and 16:30–18:00 (Spanish time, CET)). In every case, the motorcycle manufacturer's specifications (owner's handbook) take precedence.

### Which batteries are equivalent to the Exide YT7B-BS?

A direct equivalent needs what this YT7B-BS offers: 150×65×95 mm, positive on the left, the same Ah and CCA and AGM technology. The "Equivalents" section of this page gathers the recommended options with equivalent performance.

### Exide ET7B-BS or Varta YT7B-BS: which one to choose?

It shares the JIS code YT7B-BS with the ET7B-BS: they are interchangeable on the same bike. Compared with the ET7B-BS it has 35 A of cold cranking more. It costs 13,10 € more. If you want to save or the ET7B-BS is out of stock, it is the safe alternative: same dimensions, same polarity and official warranty.
