Nano-Phosphate lithium-ion battery cells now come in more than 56 of the maker’s cordless tools. These batteries last two to three times longer than other lithium-ion batteries, the maker says, and can be recharged 2,000 times. The batteries also offer more power, run time, and durability than other lithium-ion models, the company says. DeWalt worked with A123Systems, an MIT battery developer, to come up with the formula. Three platforms are available: 18, 28, and 36 volt. 800.433.9258. www.dewalt.com.
