On the batteries there will be a date stamp, these change depending on the battery manufacturer. Some are day/month/year, while some are month/day/year, while others are a circle with an arrow pointing to the month and year. However, I'm guessing that a golf cart with that year probably needs new batteries, you can check out http://www.batteryinternational.com/golf-cart-batteries.html for a replacement.
