Since batteries are critical to the operation of hp laptop, Diggingshop offers an extended battery warranty that provides coverage on batteries for up to three years ? that is 2 years beyond the 1-year standard limited warranty that comes with all laptop batteries. It can also help reduce the costs and effort involved in replacing out-of-warranty batteries.

A fast-charging laptop battery that promises to last at least three years without any degradation in performance is coming to the market as an option with HP laptops. The Sonata battery is the product of three years of development work by Boston-Power and will be rebranded by HP as the ?Enviro? battery and offered from early 2009 with select machines.

The hp dv4000 battery can be charged to 80% of capacity in 30 minutes, which could be useful for travellers who only have a limited amount of time near an electric outlet, and will go 1,000 charges before the battery?s capacity begins degrading. That?s a charge a day for three years ? or four years if it?s only used on weekdays ? so it should last the average life of a business laptop. Common laptop batteries today start to degrade after 300 charges.high quality laptop battery with 3-year warranty
