    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.

    The 147-B3121 features an industry leading energy to weight ratio. Enhanced Mat Technology (more surface area on the lead plates) combined with calcium full frame power path grids (increase cranking power), yields over 1300 Pulse Cranking Amps. With a weight of only 21 pounds/9.5kg, the B2015 is 10-30 pounds lighter than a standard battery of equal power. It also has a very high reserve time of over 1he 15 minutes to ensure the power to start even after using the vehicles accessories.

    Durability was also designed into this battery. Using high density oxide, Braille was able to offer a battery with true deep-cycling ability over the life of the battery. Heavy duty vibration resistant power posts resist cracking and deterioration common to many lightweight batteries used in harsh automotive environments. The 147-B3121 is a sealed unit that can be mounted in any position safely using its adjustable automotive terminal posts.

    Smaller Battery, Same Power
    It's no secret that the lightest car retains the advantage in virtually any motorsports competition because it accelerates quicker, apexes faster, and stops shorter. That's why automotive enthusiasts continue to run Braille Advanced AGM Lightweight Racing Batteries. Barely tipping the scales, these batteries trim 25 pounds of weight or more off the front end of most vehicles, which results in a lower center of gravity and improved handling, especially when used in conjunction with other Braille lightweight parts.

    • Patented "sealed valve regulated" design completely eliminates acid spills and corrosion on terminals
    • Environmentally safe and does not need filling or maintenance
    • Dual removable terminals allow battery to be mounted in a variety of vertical or horizontal positions
    • Patent-pending high-quality brass SAE terminals designed to distribute the battery's electrical load
    • Stainless steel terminals allow higher bolt torque and help keep battery connected even in high-vibration environments
    • Every Braille Battery is performance certified and fully charged before shipping
    • Green-friendly manufacturing process with the highest concern for the environment and quality... recycled lead, plastic, and stainless steel ensure we'll have a future to race towards

      Note: AGM (Absorbed Glass Mat) batteries are fully charged, ready to install, and compatible with a vehicle's charging system. If additional charging is ever needed, an AGM-compatible charger will be required.
