Braille Intensity I31S battery has max cranking power and in many cases will replace a pair of 80 lbs lead batteries and still have superior cranking power!  


Braille Lithium delivers a higher, cleaner voltage which improves the performance of every electrical component and has shown to provide: quicker starting, improved management & data logging performance, less horsepower draw from the alternator due to efficient charging (5 times faster than lead), will last 3-5 times longer (especially under the harshest environments), much more reliable, all of this on top of the significant weight savings. They also don’t self-discharge, so if the battery is disconnected (no draw or via power disconnect switch), they can sit for over a year and still have over 13 volts to start the vehicle. To get all these benefits in one simple step makes it a very cost effective upgrade!!

NOTE:  All lithium batteries are hand built in Sarasota, Florida and production lead time can be up to 1-3 business days depending on model, time of year, order volume and various factors.
