There is an even worse case. Friend of mine, owns a Punto. Bought the car late August 2012. Few weeks later, planning on a long drive, he packed up, got into the car and cranked. Nothing. Completely dead. Called RSA, who promptly came, found that the negative terminal was covered with bluish deposit. Cleaned the same, fixed everything back and the car started. Few weeks later, he had the same problem again. This time, he went to the SC, who again cleaned it, diagnosed that the clamp was loose, even after fully tightening the bolt. As usual, spare not available. They claim to have placed an order and 40 days later, the part has still not arrived. As a stop gap measure, they wisely decided to put a screw alongside the lead post, partly into the battery (spot indicated by black circle below) Sorry. Did not take a picture of the actual battery. Reused the picture from above post by riturajmnnit to indicate. Yesterday he was visiting me and when he wanted to leave, the car was dead. I detached the battery and cleaned everything with a solution of baking soda and later with water, only to find that the clamp on the negative terminal was broken due to the excessive tightening and the screw. I am glad the SC did not put a screw all the way into the battery. So, we both went out and bought a replacement clamp, similar to the below picture Fitted everything back, applied some grease to the terminals and all is well. I have asked him to keep monitoring the battery to see if the deposits start building up again. I could not see any cracks on the battery casing, so doubt if the deposits will recur. I fail to understand, why SC's are so callous in their attitude. I mean, they know the clamp is loose, they know that will cause deposits, which will cause problems for the customer, they claim they are not able to source a spare even after 40 days, lost the protective cover of the positive terminal in the process and to top it all, they decide to put a screw into the battery :A :A Rajan PS: My friend is also a member here. I will let him reveal his identity and the SC's name, if he wants to.
