# VARTA PowerSports AGM Active Batteries > VARTA PowerSports AGM Active: high-performance motorcycle batteries, many factory-activated (FA) and ready to install without handling acid. **Category:** [Start](https://baterias.com/gb/beginning) → [Batteries](https://baterias.com/gb/batteries) → [VARTA batteries](https://baterias.com/gb/batteries-varta) - **Canonical URL**: https://baterias.com/gb/batteries-varta-powersports-agm-active - **Language**: en-GB ## Description PowerSports AGM Active is VARTA's high-performance motorcycle range, with factory-activated (FA) references ready to install without handling acid. ## Technology Part of the AGM construction and boosts cold cranking current for large displacement engines and motorcycles with demanding starts. The Factory Activated versions come pre-charged and sealed from the factory: there's no need to pour acid or wait for the rest time, they are installed and work. This eliminates activation error, which is one of the most frequent causes of premature failure in motorcycle batteries. ## Applications - High-performance and large displacement motorcycles - Custom and high-compression trail motorcycles - Quads and watercraft motorcycles - Vehicles with frequent starting and high initial demand ## The range in figures References 29 Capacity 3 – 30 Ah Cold cranking 50 – 385 A (EN) Voltage 12 V Technology AGM ## How to choose If your motorcycle requires more starting torque than a standard AGM provides — typical in large twin-cylinder motorcycles and in cold climates — this is the range. Check the JIS reference and polarity before ordering. ## Naming and equivalences PowerSports AGM Active retains its designation. It is VARTA's high-performance motorcycle range, and many of its references are identified by the FA (Factory Activated) acronym. ## Frequently asked questions ### What does FA or Factory Activated mean on a motorcycle battery? That the battery arrives charged, with the acid already incorporated and sealed from the factory. It is installed directly, without pouring acid or waiting for the rest period. ### What is the advantage of a factory-activated battery? It eliminates the activation error, which is one of the most frequent causes of premature failure. A poorly activated battery never recovers its nominal capacity. ### What is the difference from standard PowerSports AGM? The Active range delivers more cold cranking current, designed for large displacement engines, high compression or demanding starts in cold weather. ### How do I find the equivalent to my current battery? By the JIS code on the label (YTX12-BS, YTZ14S and similar). It is the data that fixes measurements, capacity and polarity. ## AGM Active: the factory-activated motorcycle battery The **AGM Active** is the premium variant within the **VARTA Powersports AGM** range: it leaves the factory already activated and charged, so it's fitted straight away with no acid to add and no rest period to wait out. Compared with a conventional AGM, it offers better charge acceptance and lower self-discharge at rest, ideal for premium bikes that spend long spells parked in the garage. ### Models and application by bike - **YTZ7-S** (6 Ah / 130 A): 250-600cc sport. - **YTZ10S** (9 Ah / 190 A): premium sport-naked. - **YTZ12S** (11 Ah / 210 A): BMW R, Ducati Monster. - **YTZ14S** (12 Ah / 230 A): BMW R 1200/1250, KTM Adventure. ### How to choose your AGM Active If your bike is a high-end sport model, a BMW R, a Ducati or a KTM Adventure, AGM Active is often the manufacturer-recommended replacement. If you're after a cheaper AGM for a standard naked, check the classic **AGM Powersports** range instead; for a big Harley or jet-ski, **AGM High Performance** delivers more CCA. Always confirm the exact code and polarity on our [motorcycle battery comparison tool](/gb/comparator) before buying. ## Frequently asked questions about VARTA AGM Active ### **What does "factory-activated" mean?** Varta charges and activates it with electrolyte at the factory before shipping: it arrives ready to install, with no separate acid pack or manual activation process. ### **Is it compatible with my BMW, Ducati or KTM?** Yes, as long as you match the exact code (YTZ7-S, YTZ10S, YTZ12S or YTZ14S) recommended for your model and year; check the comparison tool with your registration or spec sheet to confirm. ### **How is it different from standard AGM Powersports?** The AGM chemistry is the same sealed VRLA technology; the difference is that Active comes pre-charged and factory-activated, with better initial charge response and lower self-discharge during long parking. ### **How long does it hold its charge when the bike is parked?** Thanks to its low self-discharge it lasts longer without a charge maintainer than a conventional AGM, though a battery tender is still recommended over a long winter.
