To be honest I dont have an answer, but deep cycle batteries need to be run dead. They don't like constant top up on trickle charge. So I'm guessing, try to flatten it down to 10% or 15% first, then charge up to 100% but don't leave it charging after.
We've been working through design for power renewables in building. They have memory if you don't treat them right, but of course it's a completely different application. We will drop charge down to 30%, but there are technical reasons for this (we need some oomph for spike loads at min charge), and we will make sure the control system doesn't keep them charging once full.
