HP and Boston Power have been testing the Sonata lithium-ion batteries for three years. The batteries were designed specifically for laptop use. After three years of use, the batteries will be able to keep 80 percent of their initial charge.Laptop battery time typically starts to drop significantly after 150 or so charges, or cycles. Boston Power says that its batteries can be charged 1,000 times and get "like new" performance.An HP representative on Tuesday said that the Sonata batteries will cost between $20 and $30 more than traditional batteries and will be available on some consumer laptop machines. There will be a three-year warranty, and no system changes are required.
