I replaced the battery in my 2007 Grand Cherokee two months ago. I purchased an EverStart battery from Wal-Mart. One month after purchasing the new battery it started to die. When I went to use my key-less entry it struggled to unlock the doors and instead of a normal horn when I locked it there was barely a noise. The next morning it was dead so I took the battery to Wal-Mart. They tested it, said it was a bad cell and gave me a new one. The replaced battery was fine for few days and then it had same problem. Took the battery back to Wal-Mart and they told me again it was a dead cell. I am now on my third battery as Wal-Mart would only give me a new battery not a refund. Is there anything in the Jeep’s electrical system that is causing my battery to die? Please advice. Thanks.
