nuts/bolts provided and hole they fit through were smaller than the exact same battery this replaces. this is weaker than the 6mm bolts my motorcycle is made to use. Drilling out the terminals did not help because the backs of them are molded to fit and hold the smaller nut, and do not fit the 6mm nut I had. I had already filled the battery with acid I bought at O'Reilly's and I needed it so I am keeping it but it was not part of the description. Otherwise it is a good battery, which is why I bought it
