## Description

**VARTA Powersports AGM Active batteries** are Varta's premium AGM range, **factory-activated** and ready to fit with no acid handling required. Built for sport bikes, premium naked, BMW R, Ducati and KTM Adventure, it spans 4 to 30 Ah with 50 to 450 A cranking current (CCA). Common codes: YTZ10S, YTZ12S and YTZ14S.
It's the best **factory-activated motorcycle battery** if you want to fit it and forget it, with no activation wait or sulphuric acid handling: better charge acceptance and lower self-discharge than a conventional AGM.

## 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.

### 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 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.
