We have two pairs of several-year-old Trojan T-105 batteries that were reassembled with new lug connectors less than a year ago. Seven of the eight terminals on them are perfectly clean; great shape. The eighth terminal is thickly-coated with green gunk on the copper lug and the battery terminal more thinly coated with white.
It's a positive terminal, connected to the negative terminal of its mate by an 8-inch 1-gauge welding cable. Cables FROM both sets of the batteries into trailer systems are all equal-length 2-gauge welding cable, which had me wondering if 1-gauge connecting cables between the pairs was a mistake, but the connecting cable between the other pair is perfectly-clean on both ends.
Is the corrosion warning me about something?
TIA
