Hewlett-Packard is offering a faster-charging and longer-lasting lithium-ion battery for 18 of its laptop models. The underlying technology comes from startup Boston Power, of Westborough, MA, which completely redesigned the cells in these batteries–a process that involved changing their shape and chemistry. Where other lithium-ion batteries typically lose half their charging capacity in just one year, the Boston Power batteries retain 80 percent of their original charge after three years. They charge 50 percent faster too.
