B3121 Features

Cubic Horsepower
At under 22 pounds, the B3121 is our lightest do eveything battery yet. 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 stanard Group 34 battery and still have enough power to crank over a large V8. Used in everything from large Harley Davidsons to Corvettes & Vipers.

Direct replacement for:
YIX30L, YB30L-B, ETX30L, HD 66010-97
