Braille Battery now has a commercial/industrial Group 31 battery. The Braille Fleet Line F31 lithium battery, combines high cranking power and high capacity in a single battery. This 24.5lb lithium battery replaces a 75lb lead battery, it has serious cranking power and more usable power, while lasting 8-10 times longer. This 'all in one' solution can be used for starting (nearly double the cranking power of the best AGM batteries) and 'deep cycle' power supply applications in a variety of vehicles (10 times the cycles of lead batteries including premium AGM) and in some cases require fewer lithium batteries to do the job of lead batteries.
Braille lithium batteries charge FIVE times faster than lead and are more efficient when charged by solar panels, they also don't self-discharge. If there is no draw on the battery, it will still be at 50% state of charge and still at 13 volts after sitting for FIVE years, just give it a top of charge and it's still within spec of new! The perfect upgrade for 18-wheelers, car transporters, lift gates, emergency vehicles, marine and other applications where a Group 31 battery is utilized.
WARRANTY: 5 YEARS - 3 Years Free Replacement, 4th year 75% and 5th year 50%
Braille Intensity lithium batteries come in common Group 34, 31 and 65 sizes. Direct drop in upgrade that is 100% compatible with ALL standard charging systems and can also be used in race cars with a 'total loss' (no alternator) setup. A lithium charger is required to keep batteries charged on vehicles with a parasitic draw (computer, alarm, etc.) but with no draw, Braille lithium batteries can sit for a year and still be at 90% state of charge. Braille is the only American Made 'Race Grade' lithium battery on the market used by more OEM factory and purpose built race cars, professional race series and also spec lithium battery in several cases around the world!
With an annual failure rate of less than 1/2 of 1% (those caused by abuse, improper maintenance, etc.), you can have the most reliable lithium battery on the market with over a decade of actual use on race and street cars for any vehicle you have!! There is a difference between the other 'consumer grade' lithium batteries with a bunch of 'bells and whistles' that don't match up to the performance and reliability of Braille 'race grade' batteries....our pedigree, racing history and customers speaks for itself!! Call Raceparts USA with any questions you may have as to which battery is right for your vehicle based on goals, usage, goals, etc.!
