the date of batts should be stamped into the lead at terminal.......the corrosion could be normal thats why you need to maintain them a few times a month...........take cable ends off 1 at a time clean end and batt terminal with a wire brush and put back on tight........this way you eliminate this kind of stuff that will effect life span and preformance of batts.........................
