The Smarter Choice for Powersports Performance

Motobatt has redefined the powersports battery by focusing on two things every rider wants: more power and easier installation. Unlike standard batteries that only have two terminals, most Motobatt models feature four terminals. This unique design allows one battery to replace several different part numbers, ensuring you get a perfect fit for your Harley-Davidson, Honda, BMW, or Yamaha without struggling with short cables or awkward reaching.

Inside the battery, Motobatt uses high-quality lead-calcium plates that are wrapped in absorbed glass mat (AGM) separators. This "dry" technology means there is no acid to spill, no water to check, and significantly better resistance to the vibrations that often kill standard motorcycle batteries.

Benefits of Motobatt QuadFlex Technology

  • Simple Installation: The 4-terminal system means you can connect your cables to the front, back, or top depending on your bike’s layout.
  • Maintenance Free: These are sealed AGM batteries. You never have to mess with acid or add water.
  • Longer Life in Storage: Motobatt batteries have a very low self-discharge rate, meaning they stay charged longer during the winter months when your bike is parked.
  • Heavy-Duty Construction: Built to withstand the rigors of off-road riding and high-compression engines.

Frequently Asked Questions

What is a "QuadFlex" battery?

QuadFlex is Motobatt’s patented design that features four terminals (two positive and two negative) instead of the usual two. This makes the battery much more versatile, allowing it to fit a wider range of motorcycles while making it easier to attach accessories like battery tender leads or heated gear.

Does the battery come charged?

Yes. Every Motobatt battery we ship is factory-activated, sealed, and fully charged. You can take it straight out of the box and install it in your vehicle immediately.

Can I use this in my BMW or Harley-Davidson?

Absolutely. We carry specialized high-output models like the MBTX20UHD and MBYZ16HD specifically designed for the high-cranking requirements of large V-twin engines and luxury touring bikes. Many of our Motobatt options are direct upgrades for Yuasa and other factory-installed brands.

Is this an AGM or a Lithium battery?

Motobatt batteries are high-performance AGM (Absorbed Glass Mat) batteries. They offer the reliability and safety of lead-acid technology but with much higher efficiency and no maintenance required. They are a great middle-ground for riders who want more power than a standard battery but aren't ready to switch to a Lithium system.

What happens if I don't ride for a few weeks?

Because these are AGM batteries, they hold their charge much better than standard batteries. However, if you plan to leave your bike for more than 30 days, we always recommend using a maintenance charger (like a Battery Tender) to keep the battery in peak condition.
