New Asus Laptops Have 3-Year Battery Warranty

This battery will be good for over 1000 cycles, matching Apple's claims for its latest round of MacBooks.

Along with hard disk drives, the most likely thing to fail in laptop computers is the battery. While the battery is subject to wear and tear use more than any other part, it's still covered by the same limited warranty as most other parts – unless you have one of Asus' new laptops.

Asus has announced that its B Series of notebooks come with a better battery: Boston-Power’s Sonata. The Sonata is a long life battery from Boston-Power's latest lithium-ion technology platform that provides triple the lifespan of typical notebook batteries.

Boston-Power says that the Sonata 4400 has a cycle life of over 1000 cycles at 100 percent Depth Of Discharge (DOD). It also has a fast charge:  80 percent capacity in 30 minutes; 40 percent capacity in 10 minutes; and a energy density of 180 Wh/kg.

Thanks to that, Asus is offering a three-year warranty on the battery as well as the notebook.

“Today, our portable computing devices are an extension of ourselves and integral to our work and leisure-time activities,” said Boston-Power Vice President of Marketing Sally Bament. “To fully capture the benefits of mobility, users are seeking dependable, high-performance, safe and environmentally sustainable batteries. Boston-Power has established a global reputation for leadership in delivering those solutions. Teaming with ASUS is a tremendous endorsement of Sonata and our lithium-ion battery platform.”

The Asus B53 is available immediately and the Asus B43 will be available in the near future.

Boston-Power technology is also being used by HP for its Compaq, EliteBook and ProBook laptops.
