    Braille Batteries are used by racers all over the world in the 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. The Spec 147-B2015 is also perfect for daily street use, even in colder climates. Braille developed the 147-B2015 to excel at racing and to easily power street vehicles equipped with A/C, stereos and power accessories.

    The 147-B2015 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 425 Cold Cranking Amps and 1050 Pulse Cranking Amps. With a weight of only 15 pounds/6.8kg, the 147-B2015 is 10-30 pounds lighter than a standard battery of equal power.

    Durability was also designed into the 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-B2015 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.
