It's a solid battery. This battery DOES NOT come with acid, you'll have to buy it separately. I went to AutoZone and bought some generic acid, they filled it up and charged it overnight for me. After picking it up I tossed it into a Honda CMX250c and it worked flawlessly. Haven't had it long enough to judge its lifespan, but for now it holds a 12 volt charge no problem. August 4, 2014
