I35X - Intensity Lithium Group 35 battery

Due to extremely high demand and large orders of our lithium batteries, production lead time is 3-5 business days.  We are expanding our production capabilities and will get products out as fast as possible.   Thank you for your understanding. 

Braille I35X (right positive) is the ultra-lightweight lithium upgrade in a common Group 35 size used in Nissan Z cars (2002 to present), Acura and other Japanese Imports. 

- Max weight Savings!! (Only 10 pounds vs 35 in a lead battery)

- 100% compatible with ALL standard charging systems

- Can be used in total loss (no alternator) applications

- True "Race Grade" lithium battery Made in USA (Sarasota, Florida)

- Most reliable lithium battery on the market 

- Over a decade of use in street & race vehicles & used by more professional race teams, car builders and race series globally than any other lithium battery on the market!! 


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!!
