Laptop batteries power the laptop when it is not or cannot be plugged into an electrical socket. This makes the laptop portable, allowing the user to use the laptop whenever and wherever they choose. Laptop batteries have a normal lifespan of 12 to 36 months. During this time, the battery life will slowly diminish, meaning the battery won't be able to power the laptop for as long. However, reconditioning the battery can help recover or restore some of the lost efficiency on NiCD or NiMH batteries. There is no way to restore or recover a lithium ion battery and draining the battery should not be purposely done.

Plug the AC adaptor into the laptop. Allow the battery to fully charge. This process will take four to eight hours depending on laptop battery type and size.

Remove the AC adaptor. Turn the laptop on.

Allow the laptop battery to continue to provide power to the laptop until the battery is completely drained. Once the laptop shuts off, the battery has been drained, or discharged.

Perform this process a total of three times prior to the batteries first use and every three months thereafter. You can also go through this process when you notice a loss of efficiency. If you do not perform this process, you may not get full life from the battery.
