How long does your laptop battery last? When should I consider replacing it ?
All rechargeable batteries wear out with time and usage. As time and cumulative use increase, the performance will degrade. For the typical user, noticeable reduction in run time generally will be observed after 18 to 24 months. For a power user, reduction in run time generally may be experienced prior to 18 months. We recommend buying a new laptop battery when the run time does not meet your needs. Information on Extending the Life of your Battery.
How should I choose between two laptop batteries with different Watt hours (Whr) available on one system?
