How to Replace Your Laptop Battery

Remember, safety always comes first.

Step 1: Create a Backup

Before starting any hardware adjustment, create a backup of your system’s files and data. In most cases, replacing your battery won’t affect your files, but it’s always better to be on the safe side.

Step 2: Find a Compatible Battery

Search for a replacement battery that’s compatible with your specific laptop model. You can often find this information on your existing battery, in your laptop’s manual, or on the manufacturer’s website.

Step 3: Purchase Your New Battery

You can often buy your new battery directly from your laptop’s manufacturer or from online retailers like Amazon. Always buy from reputable sellers to avoid counterfeit products that can pose safety risks.

Step 4: Turn Off Your Laptop

Prepare your laptop by performing a system shutdown and unplugging the charger. Make sure your laptop is completely turned off before proceeding.

Depending on your laptop model, the battery may be internal or external.

For external batteries:

  • On the underside of your laptop, locate the battery lock or latch.
  • Slide the latch or unlock the lock to release the battery.
  • Gently remove the battery from the socket.
  • Position your new battery where the old one sat and slide it in until the lock clicks, securing the battery.

For internal batteries:

  • You may need to remove certain parts of your laptop to access the battery. This usually involves unscrewing the back panel of the laptop.
  • Once you’ve located the battery, carefully disconnect it from where it’s plugged in.
  • Remove any screws securing the battery in place.
  • Gently lift the battery out, avoiding touching any other internal parts of your laptop.
  • Place your new battery into your laptop, reconnect it, and screw everything back together.

Step 6: Dispose of Your Old Battery

Certain retailers may accept your old battery for safe disposal, or you can find a local recycling facility that accepts batteries.


Replacing your laptop battery can be a simple and affordable solution to extend your device’s lifespan. This guide should help you comfortably replace your laptop battery when required. However, remember that if you feel unsure at any point, consulting with a professional may be the best choice.
