"I am in the automotive field and have been for years, meaning I have run into or heard just about every complaint. The guys at Black Diamond are great. Went in to purchase a starting battery, the parts guy was busy, from being in there quite often I believe it was the finance manager that stepped in to help me. I just wanted a starting battery, instead, he offered to test it instead of just sell me one. Cool dude. It was still good but had very low reserves. This allowed me to make the decision about whether or not I wanted to purchase one and I did! That thing had been in there since 2008! Great battery, great service. BTW see Nick Hill if you need a motorcycle."
