Battery posts turning Black?

appreciate the info guys. I think my issue after all of the research is that if you drain the batteries and let them sit for awhile without recharging them, then you have an issue with "seepage." I will make sure from now on to throw them on the charger after getting home instead of letting them sit for awhile and charging the day before I go somewhere... and I will now throw them on periodically through the winter. Right now they are cleaned and charging, the levels all looked good.
