Changing Laptop Batteries

Changing aToshiba laptop battery is a relatively simple process. Typically, a new lithium Ion laptop battery will give satisfactory performance through approximately 500 charge-use-recharge cycles. This translates to approximately three years of working life with light-duty use.

Early laptops were run on standard AA size batteries. However, they consumed so much power that they could run on one set of HP notebook batteries for only a few hours. The first commercial IBM-compatible laptops were small and light enough to be carried in a backpack, and could be run on lead acid batteries, the type used in cars.

The latest generations of batteries used in laptops are called ‘smart batteries’. This is due to the ability of the battery to communicate with the laptop user. Unfortunately, the definition of a ‘smart battery’ is not universal, but varies among different manufacturers and regulatory authorities. Some manufacturers call their Dell laptop batteries ‘smart’ because their batteries incorporate a pre-programmed chip that sets the charger as per standard requirements.

Most ‘smart’ battery chargers are controlled by the parameters of the chemical cells. Once the chemical cell has degraded, the laptop battery has to be changed. In some cases, the chemical part of the battery can be fully restored but the fuel gauge may become inaccurate or other data may get corrupted. In such cases, even though the digital readout becomes inaccurate due to malfunction, the battery will still fully charge and function normally for some time.

At the end of its working life, the reversible chemical processes inside a laptop battery degrades substantially. This leads to a state where the battery is unable to provide power to the laptop unless it is connected to the main 110 Volts supply through an adopter. This means that the laptop effectively becomes a desktop.

When the time comes to change the laptop battery, it is better to buy a replacement battery from the agency, which sold the laptop. It is also advisable to request the battery suppliers to replace the battery, as they would be more familiar with the procedure.
