Guide to Replace your Laptop Battery Pack

Your laptop battery is influenced by many factors, including age, environmental conditions and frequency of use.

Each laptop battery has a finite number of cycles that it can be charged and discharged. The number of cycles can be anywhere from a low of around 300 to a high of about 1200. However, 500 charging cycles is pretty typical for most standard extended laptop batteries. Battery performance begins to deteriorate once this maximum number of charge cycles has been reached.

The laptop battery’s ability to power the laptop computer will depend on several factors, most notably the hardware that is installed in the laptop and the number and complexity of the software applications that are being used. Generally speaking, the battery should be able to power the computer for two to three hours before it needs to be recharged. As previously stated, battery life is dependent on the number of cycles that the battery is charged and discharged. This will translate to a normal battery lifetime of about 1.5 – 2 years. For example, we have found that the Dell Inspiron 1520 Battery averages around 1.5 years under normal usage conditions. When the laptop battery has reached the end of its useful life, you must find a replacement laptop battery for your computer.
