HP plans to offer as an optional upgrade for some consumer notebooks a new kind of lithium ion battery that charges faster than regular batteries and lasts three times longer (1,000 charges compared with the typical 300). The battery is made by Boston-Power, which announced iut as the Sonata battery. HP will re-brand the battery as the HP Enviro battery, and start offering them early next year. The new battery should allow an 80-percent charge in thirty minutes, which is better performance compared with conventional lithium ion batteries. 

HP has not announced pricing.
