5.70*kg* Weight

With **18 Ah** at **12 V** and **230 A** of cold cranking current (EN), the **Exide ETX20CH-BS** with AGM technology replaces the original battery of motorcycles, scooters, quads and personal watercraft. Its 150 × 90 × 160 mm and the positive terminal on the left make it the exact replacement for the 18 Ah battery fitted as standard to many motorcycles.
- Compact and lightweight format.
- Holds its charge through winter storage.
- Sealed and ready to fit, no acid handling.
- AGM: faster recharging and better cycle resistance than a conventional battery.

### What the Exide ETX20CH-BS is for

Designed for motorcycles, scooters, quads and personal watercraft, the Exide ETX20CH-BS replaces the original battery of bikes that use this code or format. Check the position of the positive terminal before ordering. Check that it matches your current battery in dimensions, terminals and hold-down: this reference has a weight of 5.70 kg, M04 terminals and B0 hold-down.

### Size, terminals and hold-down of the Exide ETX20CH-BS

It has external dimensions of 150 × 90 × 160 mm and weighs 5.70 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. 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 ETX20CH-BS: Moto AGM range and AGM technology

Within the Exide catalogue, the **Moto AGM** series groups the references designed for this use. The ETX20CH-BS is the 18 Ah model of that family, with the same performance as its siblings in other sizes.
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.

### 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. At baterias.com we work directly with the manufacturer or its official distributor: real stock, brand-new product and official warranty.

### Manufacturer's warranty

The Exide ETX20CH-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

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

Orders placed **before [[ks:cutoff]]** with the battery in stock ship the same day. Delivery in mainland Spain and Portugal takes 24-48 working hours; for the Balearic and Canary Islands and the rest of the European Union allow 3 to 5 working days. You have **[[ks:return_days]] 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 ETX20CH-BS model AGM? What does this technology offer?

Yes. The ETX20CH-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 ETX20CH-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 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 ETX20CH-BS model?

Expected lifespan of the Exide ETX20CH-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 measurements of the ETX20CH-BS model?

Dimensions (length × width × height) are 150×90×160 mm — also written as 150x90x160 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 ETX20CH-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 ETX20CH-BS typically fits a wide range of European vehicles thanks to its standard DIN case format.

### What are the equivalents of the ETX20CH-BS model?

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.
