It spans 4-30 Ah with references such as ETX5L-BS, ETX9-BS, ETX12-BS, ETX14-BS and ETX20L-BS — Exide's naming for the familiar YTX codes. It is the standard **12V motorcycle battery** for most modern bikes and scooters with electric start: from the urban moped to the daily maxi-scooter, plus naked, trail and custom bikes and quads, with excellent vibration resistance. ## AGM 12V motorcycle batteries: reliable starting, zero maintenance An **AGM motorcycle battery** (Absorbed Glass Mat) holds the acid in glass-fibre separators: it is sealed, will not leak even when the bike leans over and copes with vibration far better than a conventional battery with filler caps. In practice you fit it, connect it and forget it — no level checks, no topping up with distilled water. Within the **Exide motorcycle battery** line-up, the AGM 12V series covers 4-30 Ah. The ETX naming matches the familiar **YTX** codes.

A conventional battery has filler caps, needs its electrolyte level checked and must always be mounted upright. ### **Is an ETX battery the same as a YTX?** Yes: ETX is Exide's naming for the YTX standard. An ETX12-BS shares dimensions and polarity with a YTX12-BS, so it is a direct replacement. ### **How long does an AGM motorcycle battery last?** It depends on use: very short trips and months of storage without a trickle charger wear it out fastest. Ridden regularly, it clearly outlasts an equivalent conventional battery.
