My dad has a Honda Rancher that has sat in his garage through winter. The 4 wheeler started up fine a few weeks ago. It was ridden as recently as April 2. I guess the cold spell we had last week froze it up or whatever and the battery is dead now. He also says he may have left the key in the ignition, though not turned on. My question is, how do you charge this 4 wheeler battery? I am totally ignorant when it comes to 4 wheelers, so whatever you guys say sounds good to me. Lastly, the 4 wheeler pull starts fine, the push button start is just dead. Thanks all.
