Laptops Arena

From my experience, the 2 most important features of a laptop computer are the weight, which has to be very light for portability, and the battery life that has to be long enough to allow me finish my work. A long enough battery life would mean about 6 hours.

HP has just introduced its 12-cell Multi-Charge Extended Battery model for notebook computers, which provides up to 8 hours of continuous operation. It plugs into the AC adapter port and allows you to check the charge via the fuel gauge without needing to turn on the computer.
HP also specifies that the new battery was tested with all HP laptops that are compatible with it and comes with a 1-year limited warranty.

Notebooks compatible are: HP Pavilion dv4, HP Pavilion dv5, HP HDX 16, HP G50, G60, G70, Compaq Presario CQ40, CQ45, CQ50, CQ60 and CQ70.
You can get it at a price of $169.99 from HP's official store.
