Asus adds laptop batteries longevity to its notebooks

The latest laptops from Asus offer something better than longer battery life - longer-life batteries. In announcing its B-series for business use, the company claimed to be the first to offer a laptop warranty that covers the battery life for three years. Current batteries tend to fade with each recharge but Asus promises its batteries will still maintain 80 per cent of full charge under the guarantee. These are Lithium-ion batteries, like any other laptop batteries, but using chemical and design features for longevity. The Asus claim to be the first to offer the warranty is not strictly true, as HP already sells Sonata batteries under the same conditions.
