When championships are on the line, and performance is the only thing that matters, Full Spectrum Lightweight batteries are the only choice. Our batteries are designed with one goal in mind: winning.
Full Spectrum's fanatical attention to performance has helped our customers win more championships in motorcycle racing than all other lightweight battery companies combined.
The same exact battery that powers Ryan Dungey's KTM, Kenan Sofuoglu's Kawasaki, and HTP Performance's Suzuki is available to you here.
If your positive cable is on the right side, install the battery that way. If on the left, flip the battery around. With one additional mount point, you can attach your accessories to the unused terminal hole, instead of going through the hassle of attaching accessories and the bike's battery leads to the same connection.
Compatible with traditional battery trickle chargers & Lithium Ion-specific chargers: The battery's internal management system is able to intelligently apply charge to the battery. This means that whether you are using a traditional Battery Tender Junior, or a LiOn-specific charger, you can be assured that you will not be harming your battery!
This battery features an exclusive integrated controller called "Intelligent Pulse Technology Battery Management System". Part of this system is called IPT Reset, which is basically a "last chance start" or "emergency start" button on the top of the battery. The short version is this: if you manage to drain the battery somehow- leaving the key on for a week, LED lights used at a bike night draining the battery, whatever it is- at some point the IPT will cut off the power discharge, stopping the battery from being drained to the point of damage.
Full Spectrum Power has adjusted that "cutoff point" to leave just enough power in reserve so that you can press the "IPT Reset" button on the top of the battery and you will have enough power to start your bike! How cool is that? Here is what this means: You won't be stranded somewhere. You won't need a jump start. You won't need to wait while you charge your battery in the garage. You just press the button and go.
No compromise- just performance.
Nothing is more frustrating than a bike that won't start when you're about to go on a ride. Our goal with this Motorcycle Battery Buyers Guide is to help you avoid the Dead Battery No Start, Extend The Life of Your OEM Battery and Choose The Best Replacement Battery for Your Bike when the times comes.
IMPORTANT NOTE: We recommend you fully charge all new batteries before installing them. This will help you get the best possible performance and overall battery life. If you do not have a battery charger or maintenance device you can find one using the link below.
