Portable power is everywhere — from coffee shops and restaurants to airplanes and conference rooms. As computer operating system designs continue to improve, choosing the right laptop battery is essential in prolonging your computer’s life.

Laptop computers generally run on a single main battery or from an external AC/DC adapter that supplies power to the computer while charging the battery at the same time.

The capacity of your notebook is generally measured in milli-Ampere hours (mAh). This indicates how much power the battery can hold. The higher the mAh rating, the longer you can expect your replacement battery to run.

Another important factor to consider when purchasing laptop batteries is memory effect. This means the battery gradually loses its maximum energy capacity if it is repeatedly recharged after being only partially discharged. The battery essentially “forgets” it has the capacity to fully discharge.
