HP has announced a fast-charging laptop battery that promises to last at least three years without any degradation in performance, according to InfoWorld.
The "Sonata" battery, as it is called, will be an option on HP's laptops, and is the product of three years of development work by Boston-Power. It will be rebranded by HP as the "Enviro" battery and offered starting in early 2009 on select laptops. The battery will cost an extra $20 to $30 over a standard model, and will initially only be available in North America.
HP is backing up the longer-life promise with a 3-year warranty.
