Do I Need a Special Battery for My ATV with a Winch?

The short answer is that Powersports batteries are just not designed to handle the amp draw of a winch. They are not made for deep cycling, only for starting. That being said, in the real world we have winches. Having a higher CCA is a bit helpful, but what you really want is higher storage amps, and a battery capable of deep cycle.

Odyssey makes a battery that is suitable, but they do not have direct size drop-ins, so your best bet is to figure out what your maximum dimensions can be, and then size a battery from our powersports battery list. The Odysseys are the red ones. If you go with a standard battery, find the largest one that will fit, highest amps, highest CCA.
