How to Change Lenovo Laptop Battery – A Step-by-Step Guide

Laptop batteries naturally wear out over time, and if you own a Lenovo laptop, you may notice your battery not holding charge as it used to. Replacing the battery can restore your device’s portability and performance. The good news? You don’t always need a technician — with the right tools and careful steps, you can change your Lenovo laptop battery at home.

In this blog, we’ll guide you through how to replace a Lenovo laptop battery safely and effectively.

1. Identify Your Battery Type

Lenovo laptops generally come with two types of batteries:

  • External (removable) batteries – These can be easily detached without opening the laptop body.

  • Internal (non-removable) batteries – These require opening the laptop back panel for replacement.

Check your Lenovo model (printed on the bottom of your laptop or in BIOS settings) to confirm the type of battery you have.

2. Tools You’ll Need

Before you begin, prepare the following tools:

  • A replacement battery (compatible with your Lenovo model)

  • Small Phillips-head screwdriver

  • Plastic pry tool (for opening the back cover, if internal battery)

  • Anti-static wrist strap (recommended)

3. Steps to Replace External Lenovo Battery

If your laptop has a removable battery, the process is quick:

  1. Shut down the laptop and disconnect the charger.

  2. Flip the laptop over to locate the battery release latch.

  3. Slide the latch to unlock and carefully remove the battery.

  4. Align and insert the new battery until it clicks into place.

  5. Power on the laptop and check if the battery is detected.

4. Steps to Replace Internal Lenovo Battery

For laptops with a built-in battery:

  1. Turn off your laptop and unplug the power cord.

  2. Remove the back panel:

    • Unscrew all screws securing the panel.

    • Use a plastic pry tool to gently lift the cover.

  3. Locate the battery – It’s usually a flat, rectangular component connected with a cable.

  4. Disconnect the battery cable from the motherboard.

  5. Unscrew and remove the old battery.

  6. Insert the new battery, reconnect the cable, and screw it in place.

  7. Reattach the back panel and tighten the screws.

  8. Power on your laptop to ensure the new battery is working.

5. Calibrate the New Battery (Optional but Recommended)

To extend the lifespan of your new Lenovo battery:

  • Charge it to 100% and let it stay plugged in for 2 hours.

  • Unplug and use the laptop until the battery drains completely.

  • Recharge back to 100% without interruption.

This helps the system read battery levels accurately.

6. Safety Tips

  • Always use genuine Lenovo batteries to avoid damage.

  • Work on a flat, clean surface to prevent static and scratches.

  • Avoid using metal tools that may short-circuit the battery.

Conclusion

Replacing a Lenovo laptop battery is a simple process if you follow the right steps. For removable batteries, it takes just a few seconds, while internal batteries require a bit more care. With this guide, you can save time, money, and keep your laptop running smoothly.
