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: 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.

How to change the battery

Guide to replace your motorcycle battery in 10-15 minutes. Motorcycle batteries are light (2-5 kg) and usually need an 8 mm wrench.

⏱ 10-15 min🛠 Tools: 8 mm wrench (some bikes use 10 mm) · Protective gloves
  1. Step 1. Prepare the vehicle

    Park on a flat surface, switch off the engine and remove the key. Make sure all lights and electrical accessories are off. Wait 1-2 minutes before starting.

  2. Step 2. Locate the battery compartment

    On motorcycles it is usually under the seat, in the rear cowl or behind a side panel. Check the manual — access varies a lot between models.

  3. Step 3. Disconnect the negative (−) terminal

    Use the 10 mm wrench to loosen the negative cable nut (black, marked −) and remove the cable from the post. Move it aside so it cannot touch any bodywork.

  4. Step 4. Disconnect the positive (+) terminal

    Repeat with the positive cable (red, marked +). Important: never let a terminal touch metal of the car while the other is still connected.

  5. Step 5. Remove the old battery

    Loosen the hold-down clamp or the straps that secure it. Lift the battery carefully — typical weight 2-5 kg. Check the terminals are not corroded before fitting the new one.

  6. Step 6. Install the new battery

    Place the battery in the same orientation as the old one (positive terminal on the same side). Tighten the hold-down clamp firmly.

  7. Step 7. Connect the cables

    Connect the positive (+) terminal first, then the negative (−). Tighten the nuts with the wrench until each terminal does not move. Apply anti-spark grease if you have any.

  8. Step 8. Verify the engine starts

    Close the bonnet. Start the engine to confirm everything works. On cars with Start-Stop or a BMS, you may need to register the battery via OBD so the alternator applies the correct charging profile.

Frequently asked questions

Is this battery AGM? What is it for?

Yes. The ET7B-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 do I change this battery step by step?

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 this page. 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 — 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 ET7B-BS model?

Expected lifespan of the Exide ET7B-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 ET7B-BS battery?

Dimensions (length × width × height) are 150×65×95 mm — also written as 150x65x95 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.

Will the Exide ET7B-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 ET7B-BS typically fits a wide range of European vehicles thanks to its standard DIN case format.

Which batteries are equivalent to the Exide ET7B-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.
