4.90*kg* Weight

The **Exide ETX14AH-BS motorcycle battery** is rated at **12 V**, **12 Ah** and **210 A** of cold cranking current (EN) from the **Moto AGM** range, and is designed for motorcycles, scooters, quads and personal watercraft. Measuring 135 × 90 × 165 mm and the positive terminal on the left, it is the direct replacement for motorcycles fitted from the factory with a 12 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.

### What the Exide ETX14AH-BS is for

The Exide ETX14AH-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 4.90 kg, M04 terminals and B0 hold-down.

### Size, terminals and hold-down of the Exide ETX14AH-BS

In terms of format, the Exide ETX14AH-BS measures 135 × 90 × 165 mm (length × width × height) and weighs 4.90 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.

### The Exide ETX14AH-BS: Moto AGM range and AGM technology

The ETX14AH-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.

### Exide: the maker behind the ETX14AH-BS

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. We guarantee that every Exide arrives new, charged and with the manufacturer's full warranty.

### Manufacturer's warranty

The Exide ETX14AH-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

Charge with a charger that has an AGM mode: it limits the voltage and protects the glass-fibre separators. If the bike spends the winter standing, connect a trickle charger: deep discharge through inactivity is the first cause of premature failure.

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

Same-day dispatch from our warehouse for in-stock orders placed **before [[ks:cutoff]]**: 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 **[[ks:return_days]] days** if the battery has not been used (free collection on the Iberian mainland). You will receive tracking by email.

## Frequently asked questions

### Is the Exide ETX14AH-BS an AGM battery and what are the benefits of AGM?

Yes. The ETX14AH-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 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.

### How long does the Exide ETX14AH-BS battery last?

Expected lifespan of the Exide ETX14AH-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 ETX14AH-BS battery?

Dimensions (length × width × height) are 135×90×165 mm — also written as 135x90x165 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.

### On which side is the positive of the ETX14AH-BS model?

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 ETX14AH-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 ETX14AH-BS typically fits a wide range of European vehicles thanks to its standard DIN case format.

### What are the equivalents of the ETX14AH-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.
