Batteries Drain after 12 hrs

I have two 12 volt Interstate batteries with 130 AH each so 260 AH for the coach. I bought the batteries new on 7/2015 so less then 3 years old and load banked them and they tested fine. My question is I fully charge them through the generator and they only last 12 hours. I have a 2014 Four Winds 31E with standard equipment. Any thoughts? Thanks in advance.

The batteries last, depending on what devices you have on line. Are you saying you've done this before and they lasted longer? Ejk

Too me...3 years on a battery that makes it's living going from a full charge to mostly dead, over and over and over, is a good life span. I would just change them out. What's the warranty on the batteries?...the warranty usually coincides with life expectancy, not counting the free replacement period.

I 2nd that. I usually change them out in car and RV after 3 years. It is not worth the inconvenience to me of having them die at a bad time, which is every time one has failed.
