Battery Wholesale Inc. has had to make many changes throughout the years to keep its completive edge on the market, which is one of the reasons for opening its retail stores. It also has had to change with the technologies from lead acid, sealed, AGM, lithium and much more. With having to purchase all of these different products and keeping a competitive edge on the market, BWI has joined some of the largest battery buying groups in the United States. These buying groups allow BWI to purchase at the same price level as many big box stores.
