There is a myth on this forum that the old Magnetec converter chargers are battery boilers. Check the out put of your charger is it 13.6 volts or lower? My 20 year old Magnetec charges at 13.2 volts. I don't know how 13.6 v or lower can boil the batteries. Having said that I use a 40 amp B&D portable charger to charge the batteries after I dry camp, remove the cables and let the 5 amp Magnetec float charge the batteries for several days then use the battery disconnect if I won't be using the MH for a while. These chargers can fail that is why I say check the out put first if it is 14 volts or more then just use the disconnect switch after it is charged and unplug from shore power.
