Yuasa YB9L-B Yumicron Conventional Battery

This time tested battery features added power that is an outstanding benefit for heavily accessorized motorcycles or high compression engines. Its high cranking power is also a real bonus for easier starting. A workhorse battery featuring special thin separators which allows two extra plates per cell to be installed for a 30% improvement in cranking performance. Appears as original equipment on many big bikes.

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.
