Agreed if you are using a maintainer then do not use a timer.
I use a multiple output maintainer in the boat. It's mounted inside the boat and keep the batteries charger all winter long. I just plug in the boat and don't have to think about it all winter long. My batteries are lasting longer than ever and I don't have to pull then from the boat as part of my winterizing program.
