J/30 Class Association Forums J/30 Forum The Boat, Sails and Equipment Replacement Batteries

I'm planning to replace my deep cycle wet-celled batteries this year on my 1981 J/30. Any recommnedations on size, brand, supplier, etc. Plan to be sailing out of Manitowoc, WI on Lake Michigan next year and will likely be doing some coastal cruising.
