A fast-charging laptop battery that promises to last at least three years without any degradation in performance is coming to the market as an option with Hewlett-Packard Co. laptops. The Sonata battery is the product of three years of development work by Boston-Power Inc. and will be rebranded by HP as the Enviro battery and offered with select machines beginning early next year.
The battery can be charged to 80% of capacity in 30 minutes, which could be useful for travelers who only have a limited amount of time near an electric outlet. And it will go 1,000 charges before the its capacity begins degrading. That's a charge a day for three years -- or four years if it's only used on weekdays -- so it should last the average life of a business laptop. Common laptop batteries today start to degrade after 300 charges.
