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.

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 before buying.
