2013 Kubota RTV 900 winch / new Battery

[JoeG]

I've replaced my battery with an Optima Yellow top that has side and top terminals. I installed a 3500# winch, and planed on connecting the RTV as usual to the top post, and the winch to the side post. read the installation instructions for the Optima battery and they said "do not connect a winch to the side terminals". they gave no explanation, and I guess I need one. Any one have an explanation? Should I run the RTV off the side terminals, and the winch off the top? I don't understand what the difference would be. Thanks
