Braille B128L MicroLite Carbon Lithium Battery. The B128L battery weighs under 8.5lbs and Braille's Lithium-Ion Technology produces a battery with more power that is lighter, stronger and more efficient. It also allows the direct implementation of the high power lithium technology with Alternators and common charging systems.
The B128L is the most popular model in the MicroLite line and is currently used in every car in the DTM (Audi, BMW, Mercedes), SuperGT (Lexus, Nissan, Honda, Subaru) and Australian V8 Supercars (Holden, Ford, Nissan, Mercedes), along with P1, P2 and GT cars in endurance racing in the USA and abroad.
From 2017 the new IMSA DPi cars of Cadillac/Dallara were also factory equipped with the B128L lithium batteries. Over 50% lighter, Braille Lithium delivers a higher, cleaner voltage which improves the performance of every electrical component and has shown to provide:
- Quicker starting, a full volt higher than lead and less voltage drop during cranking
- Improved engine management and data logging performance, through more stable voltage
- Less horsepower draw from the alternator due to efficient charging, 5x faster than lead
- Lasts 3-5 times longer, especially under the harshest environments
- Much more reliable, with the lowest failure rates on the market
- Significant weight savings, typically up to 1/4 the weight
What's more these batteries 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.

Braille MicroLite lithium batteries are the 'spare no expense' racing models that are the smallest, lightest and most powerful on the market and are the ones used by Corvette Racing for 10 consecutive years, the Ford GT factory race cars and also are in the Cadillac abd Mazda DPi prototyes, Lexus, Audi and Mercedes AMG GT3 cars as well as those in NASCAR, Australian V8 Supercars, SuperGT in Japan and more. This lithium 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.!
