Well, I went to U Part It and checked the batteries they had and found a Honda battery with the same CCA as my old one of 585. It was priced $20, so I took a chance. Didn't see a date code but it was in decent condition. They tested it first and afterwards I had a new battery. Much better than the $110 for the right one. 52 series even fits under the battery hold down, although not as well asthe 56 series I had before.
