Advanced AGM Lightweight Racing Battery
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 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. JEGS Easy Kits are designed by JEGS Professionals to help you get all the performance parts you need.
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.
