Pros

  • β€’Provides strong cold cranking amps for reliable and immediate starts, even on demanding motorcycles like the 2012 Ducati Hypermotard 796.
  • β€’Comes with a complete acid pack for easy, mesree battery activation right out of the box.

  • β€’Exceeds manufacturer’s claimed capacity by over 10% on initial use and maintains strong performance with only minor capacity loss after years of use.
  • β€’Manufactured in Taiwan with a reliable build quality, favored as the best lead battery brand in powersports and motorcycles.
  • β€’Long expected lifespan of around years with proper maintenance like using a battery tender.
  • β€’AGM technology preferred over lithium variants in hearone motorcycle environments due to better resilience near exhausts.
  • β€’Clear and straightforward filling instructions help users properly activate and maintain the battery for optimal performance.
  • β€’Demonstrates excellent power delivery and durability, with reports of batteries lasting up to nearly 10 years without failure.

Cons

  • β€’The battery requires filling with acid and charging before installation, which means more upfront effort and safety precautions such as wearing gloves and eye protection.
  • β€’Not Japanesade, which may matter to some buyers who prefer purely Japanese-manufactured batteries, though the Taiwanese build quality is generally reliable.
  • β€’Requires a compatible AGM battery charger for proper maintenance; incompatible chargers may reduce battery life.
  • β€’Needs to be handled carefully during activation to avoid spills and properly seal after filling, which can be intimidating for some firsime users.

Bottom Line

The Yuasa YUAM6212B YT12B-BS battery is a top-tier, reliable OEM replacement for Ducati and similar motorcycles, delivering strong starting power and lasting performance when maintained correctly. Its AGM design makes it ideal for heat-exposed bikes, and it beats manufacturer capacity expectations right out of the gate. However, it does require some care during the initial acid filling and charging process, so novice battery installers should be prepared for a little hands-on work. If you want a plug-and-play option with less fuss, you may want to explore sealed or pre-filled alternatives, but for ultimate reliability and longevity, this Yuasa model stands out.
