The HP Long Life Battery helps you be productive longer than with standard solutions, and has up to a three-year life span backed by its three-year warranty, an industry first, which helps lower your cost of ownership. Other benefits include - Reduced overall battery waste by requiring fewer batteries to be used over the life of the notebook. - Construction includes an insulating safety wrap that encloses the cells, a fire-retardant casing, barrier walls that isolate cells from the Printed Circuit Assembly (PCA), and internal connections designed to prevent pinching and potential short circuits.
