how to protect laptop battery(2)
Before getting into the detail of how to protect laptop batteries, let's look at the technology. It
will help answer the question and also shed light on another, "what is a reasonable life for a
laptop battery?"
Most portable electronic devices including laptop computers are now powered by lithium-ion
batteries. Lithium-ion superseded nickel metal hydride technology providing superior power to
weight ratio, a longer discharge cycle, absence of the "memory effect" and a lower cost.
Under optimum conditions, lithium-ion batteries will provide excellent service over 300-500
discharge cycles, which equates to 2-3 years of laptop usage. That is also the average life of a
laptop computer. At that age hard drives become susceptible to problems and there will be a
new version of Windows that struggles to boot on this now obsolete laptop.
