Our aftermarket batteries are an easy to install upgrade over the OEM hardware. These batteries have a prolonged lifespan with improved durability so they stand up to the rigors of long use. These replacement batteries feature AGM (Absorbent Glass Mat) technology, to provide you with reliability and solid run time for all of those awesome power-hungry mods. Our maintenance free, valve regulated batteries have a quad terminal setup allowing you to allocate one set of terminals for the bike itself, while reserving the second set of terminals for your aftermarket 12v mods. Moreover, riders who are subject to seasonal riding will be delighted with these batteries due to their low self-discharge rates for high voltage off-season storage. We do recommend pairing your AGM battery with one of our battery maintainers / desulfators to keep your battery topped off when not riding, to extend the overall life of your battery.
