Batteries Plus, No. 19 on the Dun & Bradstreet AllBusiness AllStar Franchise rankings, connects to a network of 515 stores in order to stock more than 40,000 types of batteries and light bulbs and ensure that customers can special order obscure parts. Their batteries range from dainty watch batteries to 5,000-pound leviathans that can power forklifts, and an on-site tech center can design and assemble custom batteries or rebuild old ones. A diverse array of chargers keep systems juiced, and the shop’s bulbs range from fluorescent tubes to heat lamps. To safeguard the environment, Batteries Plus's staff recycles all types of batteries and bulbs rather than hauling them to landfills or feeding them to each other.
