Battery dates are May 2012. Thanks for your insight.
I'm not an expert on trailer batteries, but generally for car batteries, if you are going beyond five years, although its not unusual, you might expect the batteries not to go too much longer. So using this logic, your trailer batteries are 6 1/2 years old and maybe looking towards the end of their lives.
