Well the clicking means you have one of two issues, The battery itself is bad, voltage is not an accurate way to test a battery, you need to do an actual load test to determine how many amperes it can deliver under a heavy draw. The other possibility is a bad connection either corroded or loose. To find that you would need to remove, clean and reattach the cable connections at each end.
