6V Deep Cycle Batteries

I'm Using 2 deep cycle 6 volt batteries wired in series in my trailer. I bought the batteries last fall after the camping season was over for us. I put the batteries on a 12v trickle charger over the winter to keep them charged. When I initially installed them this year they still were not charged very well. After a couple of trips where I couldn't keep them charged I bought a Schumacher SE-70MA deep cycle charger to charge the batteries. When I reinstalled the batteries in the trailer and switched on the battery it blew two 40 amp and one 15 amp fuses immediately. What gives?
