I have been running 4 cart batts in the back of my Cat and am trying to reduce some weight back there. The run I have been cranking with and running ALL my accessories on was bought in Feb of this yearr and dated A-13 so it was made January of this year. These things are awesome as far a deep cycle batt goes and they run around 175 to 200 bucks new, will make someone a heck of a deal on a 6 month old battery, pm me for price.
