This battery is no joke! With 1,380 pulse cranking amps and a weight of 21lbs., the Braille B3121 battery is perfect for a car that is driven on the street or on the track.
Braille Lightweight Racing Batteries have been the battery of choice of champions in almost every form of motorsport. The Braille lightweight batteries feature an industry leading energy-to-weight ratio accomplished via Enhanced Mat Technology (more surface area on the lead plates) coupled with calcium full frame power path grids (for increased cranking power).
If Braille Batteries are in the best race cars in the world, it has to be light, safe, and durable. Heavy duty vibration resistant power posts resist cracking and deterioration. By incorporating high density oxide Braille was able to create a battery with a true deep-cycling ability over the lifespan of the battery. Because the Braille battery is sealed, you can mount this battery in any position safely and can use the adjustable posts to ensure a proper contact.
