Concorde is a leading U.S. manufacturer of AGM batteries. It's been that way since the mid 90's when they superceded the performance of Gel batteries and focused solely on their Lifeline and SunXtender AGM brands.

These days the SunXtender brand is more commonly referred or known as Concorde since BP Solar closed their doors in 2010 as this is what is printed on the side of the box when you purchase new batteries from us. SunXtender still have huge installations throughout Australia at all the countries BP service stations.
