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 Dell laptop battery when the run time does not meet your needs.
When choosing a battery, the main quality that you need to consider is the amount of energy that can be stored in a battery. This is measured in Watt- Hours (Wh). For longer runtime per charge, choose a battery with a greater Wh rating

Note: When used under the same conditions, a lower capacity battery will wear out faster than a higher capacity battery because it has to be charged more often.

How long does a Dell laptop battery last? When should I consider replacing mine?
