When my Converter failed a couple years back I got a Deltran Battery Tender. Now you are used to the little ones. This one is not so little. it has 3 modes
TENDER (like the little ones)
Boost (20 amps) auto switch to tender
Jump (70 amps brief period wants to see almost no voltage to kick it in useful for, as the name implies. starting car with dead battery worked too)
Took it 24 hours to charge my battery bank. and then I hit the road... Next stop was abou 15 miles from Progressive Dynamics. Next Stop, as you might guess WAS Progressive Dynamics.. (I know the area).
