Everything You Need to Know About Replacing a Laptop Battery

When it comes to replacing a laptop battery, it's always best to go to the PC manufacturer for the best results. Batteries from external sources can void warranties and are not always rigorously tested, and batteries are known to explode, so it's important to be aware of the risks. Before ordering a replacement battery, check the PC manufacturer's website to make sure you're getting the correct one and that it hasn't been recalled. There are also third-party utilities that can be used to determine what type of battery should be placed in a laptop.

Today, the most common type of laptop battery is lithium-ion, although older laptop computers may have a nickel-cadmium or nickel-metal hydride battery. If the laptop battery is not going to be used for a month or more, it is recommended to remove it from the device and store it in a cool, dry and clean place. It's important to condition (fully discharge and then fully charge) your laptop battery every two to three weeks. One of the easiest ways to determine what type of battery you have is to turn off and unplug your laptop and then remove the battery to look at it.

If your battery has reached this level, you can check what type of battery you need depending on your laptop. If your battery is on the recall list, contact the laptop manufacturer to have it replaced as soon as possible. The new laptop battery is discharged and must be charged before use (see the charging instructions in the computer manual).
