What voltage is your Magnatek charger putting out? My Magnatek 950 has never charged more than 13.6 v when new and now charges 13.2 v after 25 years of use. I never under stood how this voltage will destroy a set of 2 6v GC batteries or be a battery boiler. Check your output voltage, as some of these older chargers can increase in charging voltage over time and if left on for months at a time can use a lot of water. If voltage is OK you have something else going on with your batteries. Another option is to buy a portable 40 amp charger like the B&D or Stanley which will quickly recharge your batteries and has an equalizing and desulfating function and will charge and maintain your batteries much better, then use your Magnetek as a converter and to top charge your batteries after your "smart charger" says full.
