More Powerful Hybrid Batteries.

In a demonstration at the AABC conference in Baltimore this week, a rechargeable DeWalt reciprocating saw with A123 batteries (top) performed at least as well as a plug-in model by the same company. The rechargeable drill is also lighter than the plug-in version. Last fall, Watertown, MA-based startup A123 Systems announced that its advanced lithium-ion batteries would make rechargeable circular saws and drills more powerful than plug-in tools. The company, having delivered on its promise (the tools will be available at The Home Depot this weekend), has now built a battery pack that Ric Fulop, one of the company's founders and its vice president of marketing and business development, says could make hybrid vehicles cheaper and more convenient, while maintaining or improving performance.
