ASUS is the latest notebook vendor to start using Boston-Power Sonata lithium-ion technology to help extend the life of its notebook batteries.
The big pitch for the Sonata Long Life Battery is that it can triple the lifespan of a typical notebook battery, allowing for more charges and discharges without degrading performance. There is a three-year warranty on the ASUS batteries. Apparently, Boston-Power also remains the only lithium-ion battery maker to carry the Nordic Ecolabel certification, and they have now earned a similar certification in China from the China Environmental United CertificationCenter. The first model, ASUS B53, already shipping. The ASUS B43 is due soon.
