Our Braille B3121 lightweight AGM battery is our lightest do everything battery yet, weighing in at just under 22 lbs. Using our Advanced AGM racing technology, we have put a lot of power into a very small package.
With 1380 pulse cranking amps this has enough power to start more than any other battery in its weight class. This is the perfect model for those who want to shave half the weight of a standard Group 34 battery and still have enough power to crank over a street car with V8 engine & standard compression.
Used in everything from large Harley Davidsons to Hot Rods, road race cars, Corvettes & Vipers. (Note: while high in cranking amps, make sure battery has enough capacity for the vehicle intended to be used in. Not designed for big block, high compression motors (Where a full-size battery with high capacity is required).
Direct Replacement For:
YIX30L, YB30L-B, ETX30L, HD 66010-97
Common Upgrade For:
PC925 (same size, 5 pounds lighter, 50% more cranking power)
