mine came with some Japanese named brand, but didn't last long. One of my ex girlfriends, didn't listen when I said never touch or place anything on the battery. My VX was in the dealers shop for a month and a half so I kept the battery so it wouldn't dry rot. So, she placed a popcorn tin directly on top completing the positive and negetive terminals...sparks went flying... she arc welded and melted a whole in the tin, turning a space black the size of a softball and the terminals were melted and mishapen beyond reconition.

So, she bought me an Optima Redtop(the lower power one) which I replaced for the higher powered one and use for the starting battery. Then I placed a Yellow Top in place of the air box to run the winch, audio amp, air compressor and rock lights.
