Purchasing a Replacement Battery

  • PrintPrint
This document pertains to HP Notebook PCs.
The battery in a notebook PC is designed to provide dependable power; however, all rechargeable batteries gradually lose their capacity to hold a charge. Batteries made of different materials have different useful lives. For instance, with moderate use, Li-Ion batteries are expected to deliver around 80% of their original capacity after 300 charge cycles or about one year of use. This loss in capacity (aging) is irreversible.
