The install was fine but the changing of the battery caused computer issues for my car. I called the 800 number and advised the operator of the problem cause by the installer. I was told they would contact the installer than call me right back. No one from 1-800 battery has contacted me to help fix the problem. Also they state on their site that they have real time chat on line. That is not a true statement as it pertains to me. I sent an email asking questions and several hours later got a call with excuses on why it wasn’t real time. Also they charge $1.00 per mile that the installer had to drive to get to my location. If this is how the treat all their customers than I highly question the star ratings that the post on their site.
