I had two Deka group 31 deep cycle marine batteries that were only on their second season give up the ghost within a month of each other just this summer. The dealer replaced the first one on the advise of the regional rep. but they refuse to do anything about the other bat. I replaced with Interstates. Both bats that went bad were on a maintainer and always kept topped with distilled water. I for one won't be putting any more Deka bats into any of my equipment again.
