FYI, here is the equipment I'm using.
1 x big truck battery charger. It has 2A, 40A and 200A settings. It charges at about 15V on the 40A setting. My batteries would only take 10A at that voltage when I was starting. I use this charger to wake them up and get them accepting some charge.
2x small chargers, both with 2A and 10A settings. I used these chargers to bubble the batteries over night. These chargers put out about 13.5 volts.
1 hydrometer
1 100A CCA battery load tester
1 200 watt inverter and a 120V "load". I'm using 2 x 75 watt incandescent light bulbs on switches.
Multimeter
