Advanced AGM Lightweight Racing Battery
Braille Batteries are used by racers all over the world in the NASCAR, FIA WRC, FIA Formula Racing, Speed World Challenge Series, SCCA ProRally Series, SCCA Regional and National Racing, NASA Touring Cars, NIRA, NOPI and Battle of the Imports Drag Racing Series. Braille Batteries are also designed for deep-cycle use in premium vehicles with enhanced reliability and performance.
Seeing a need for a Braille Battery that had extended reserve time and amp hour capacity, Braille changed the internal grid structure to suit customers looking for the highest amp hour to weight ratio for an AGM battery. The Spec 147-B3121 is
perfect for daily street use, even in colder climates. Braille developed the 147-B3121 to excel at competition use and in situations where the battery is relied on to perform at a higher level than other batteries.
This includes extreme audio systems and insane motors."
