Interstate All Battery Center, Burnsville

In 1952, after years of ferrying car batteries to wholesalers throughout Dallas in his trusty red Studebaker pickup truck, John Searcy opened a shop of his own. Now a national franchise with more than 300 locations, Interstate All Battery Center powers up gadgets from a catalog of more than 16,000 batteries. Specialized cells from an array of brands including Apple, Motorola, and Creative Labs power home electronics, including the cell phones and singing wall fish that run constantly in most modern households. Cordless tools purr warmly, and medical equipment, such as hearing aids and wheelchairs, continue their crucial functions with fresh energy. The shop also powers up vehicles from golf carts to vintage cars to RVs with batteries from Audi and other companies. The staff collects and recycles upward of 850 million pounds of batteries each year.
