## Description

**Exide Bike 12V AGM batteries** for motorcycles are supplied dry, with a separate acid pack that you add just before fitting. The range covers 4-30 Ah and directly replaces YTX, YTZ and YB codes from other brands.
Because it is activated at the moment of installation, an **Exide Bike motorcycle battery** always arrives fresh and delivers 100% of its capacity from the very first start. It is the classic workshop choice: a maintenance-free AGM motorbike battery for scooters, naked bikes, sport-tourers and cruisers.

## Exide Bike 12V AGM: strong starts, activated at installation

**AGM** (Absorbent Glass Mat) technology holds the electrolyte in glass-fibre separators: once filled and sealed, the battery cannot spill, needs no maintenance and withstands vibration far better than a conventional motorcycle battery. References with the -BS suffix come with a **separate acid pack** (Bottle Supplied): the battery keeps perfectly while in stock and is activated when filled, right before fitting.

### Exide Bike AGM models and applications

- **ETX5L** (4 Ah) — battery for 50-125cc scooters and small bikes.
- **ETX12-BS** (10 Ah) — battery for 600-900cc naked bikes.
- **ETX14-BS** (12 Ah) — battery for sport-touring motorcycles.
- **ETX20L-BS** (18 Ah) — battery for customs and cruisers, including Harley-Davidson.

### How to choose your compatible Exide Bike battery

Note the code of your current battery (YTX, YTZ or YB), find your bike in the [comparison tool](/gb/comparator) or search by [number plate](/gb/battery-finder-by-plate). Prefer a factory-activated, sealed battery? See the sister Bike AGM Ready range.

## Frequently asked questions about Exide Bike AGM batteries

### **What is the difference between Exide Bike AGM and AGM Ready?**

The Exide Bike AGM is supplied dry with a separate acid pack and is activated when fitted; the AGM Ready leaves the factory activated and sealed, ready to install. Once fitted, both are maintenance-free AGMs with equivalent performance.

### **Is it compatible with YTX, YTZ and YB codes?**

Yes. Each Exide Bike AGM reference directly replaces its YTX, YTZ or YB equivalent with the same dimensions and polarity; the ETX12-BS, for example, replaces the YTX12-BS.

### **How long does an AGM motorcycle battery last?**

It depends on use and state of charge: a well-kept AGM usually outlasts a conventional battery. If the bike sits unused for weeks, a battery maintainer clearly extends its life.

### **Does it need maintenance after activation?**

No. After the initial fill and sealing the battery stays closed: no topping up or level checks, just keep it charged during long lay-ups.
