Just because the boat is new doesn't always mean you get new batteries. Look on the battery for a small sticker and it should have a date code telling when the battery was manufactured. There should be an alphabetical letter for the month and a number for the year. For example, H-07 or H-7, would mean that the battery was manufactured in August of 2007. A is Jan, B is Feb, and so on. Always be sure to check this when you buy a new battery off the shelf as well. Good luck and hope this helps! :D:D:D
