My understanding is that it depends on a bunch of factors, including the number of charge/discharge cycles the batteries have been through, how deeply they've been discharged, the conditions in which they've been kept and the quality of your charging system. I've read that car batteries typically have a life expectancy of five years, but they're used differently.
You might want to pick up a high quality volt meter and monitor the rate of discharge on your batteries. Humminbird makes an inexpensive portable meter. It measures battery voltage. A 12 volt battery will put out around 13.5 volts when fully charged and around 10.5 volts when fully discharged. As batteries age, I'd expect them to discharge at a faster rate. In other words, they won't hold a charge as well as they did when they were new.
