Changing Laptop Batteries

Changing a 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.
Purchase a new battery. Refer to your laptop owner's manual to determine the type of battery you need. Compatible laptop batteries can be purchased from computer parts dealers, the laptop manufacturer, or an online auction.
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 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.
Install the new battery by first aligning its receptor pins with the pins in the battery compartment. Push down on the opposite end to snap the battery in place. Secure the lock/latch mechanism by sliding it back to the original position.
Plug your laptop into an electrical outlet to charge the new battery. It usually takes about 24 hours to complete the first charge. Subsequent charges will only take a few hours.
Install the new Dell battery by simply popping it into place. The alignment of the battery should be easy to figure out, since there's only one side of it that connects to the receptor pins in your notebook's battery bay.
Save any open files on which you're working. Since turning the system off isn't required when changing the battery, this is more of a precaution than a necessity.
At the end of its working life, the reversible chemical processes inside a laptop battery degrade 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.
The battery on a Dell laptop allows you to use your computer in various locations without losing power, as compared to a desktop computer, which always needs to be plugged into an outlet to work. Unfortunately, the battery eventually stops holding charge as it gets older. If that happens, you need to change the battery out for a new one--a fairly easy task.
Put the battery into the empty battery slot. One side of the battery has a connector. Match that side up with the connector in the battery slot, and then push down on the battery to latch it into place.
