FAQS about Motobatt AGM Quadflex Batteries

The Motobatt QuadFlex AGM motorcycle battery uses Absorbent Glass Mat (AGM) technology, offering superior cold cranking amps (CCA), a longer service life, and a maintenance-free design. It is considered one of the best motorcycle batteries for performance, reliability, and durability, especially for motorcycles, ATVs, UTVs, and other powersports vehicles.

Unlike conventional flooded lead-acid batteries, QuadFlex AGM batteries provide greater vibration resistance, faster recharge rates, and longer cycle life. They also come fully sealed, making them spill-proof and maintenance-free, ideal for riders in rugged conditions or who demand consistent performance.
QuadFlex batteries feature a universal-fit multi-terminal design and are compatible with over 250 motorcycle models, as well as scooters, ATVs, UTVs, and snowmobiles. This makes them a versatile choice for those looking for a reliable motorcycle battery replacement or powersports battery upgrade.
Thanks to the QuadFlex 4-terminal system, installation is easy and flexible. You can mount the battery in different orientations to fit a wide range of battery compartments without needing adapters or cable extensions. It’s a plug-and-play battery upgrade for most powersports vehicles.
No. Motobatt QuadFlex batteries are fully sealed, non-spillable, and completely maintenance-free. There’s no need to monitor electrolyte levels, clean corrosion, or refill with water—just install and ride. This makes them a perfect low-maintenance battery solution for motorcycles and ATVs.
