This winter I installed two new Trojan T-1275 12v batts in parallel for my house bank. The boat's on the hard, but I have plugged into shore power on a couple of boat work days and run my Sterling ProCharge Ultra charger (with temperature sensor) to bring the new batts up to full charge. When I get to the boat, my voltmeter shows the rested bank(no charging for days) is at 12.9 volts--I have nothing drawing on the bank. But when I turn on the charger, it stays in bulk mode the whole day, charging at 14.8v, with a draw of .8 amps or so. I have selected the flooded lead acid profile, and I assume the higher than 14.4 v (or whatever it is supposed to be) is because of the low temps, but why doesn't it ever go to float?
