In your OP you said you did not want to spend $200+ for a new charger. I have the Magntek 950 and it will only charge at 5 amps. I bought a 40 amp B&D charger for $50 to use when I dry camp which is 95% of the time. This will bring a pair of 6v GC batteries up from 50% to 80%in about 2 hrs and has a equalize and desulphate mode in it also. The Magnatek is a simple durable ferrostat type charger and will last for a long time . I find the smart charger does not fully charge the batteries and several days of float charging with the Magnatek prior to camping will give me 2 more days of camping before batteries reach 50% SOC. After batteries are fully charged the Magnatek will float at 13.1 volts.
