Show original supplier description
The Braille Battery B3121C is a lightweight, high-performance AGM battery engineered for racing and demanding street applications. Weighing just 21 pounds, this battery provides 1380 pulse cranking amps (PCA), offering more power than other batteries in its weight class and sufficient to crank V8 engines with standard compression. Utilizing Advanced AGM racing technology, the B3121C is designed to shave significant weight off standard batteries, making it ideal for performance vehicles. It is recommended for use in a variety of applications, from large Harley Davidsons to Hot Rods, road race cars, Corvettes, and Vipers. However, users should ensure the battery has adequate capacity for their specific vehicle's needs. Unlike metal cases that conduct heat, the carbon fiber construction helps keep the battery cooler. Note that the carbon fiber case may be slightly wider and longer than standard cases, potentially requiring minor modifications to battery boxes with tight tolerances. Physical dimensions include a width of 5.2" (132mm), height of 6.9" (177mm), and length of 6.8" (174mm).
