When your laptop battery stops working, it can be frustrating. You may think that you need to buy a new battery, but this is not always the case. In many cases, you can recondition your laptop battery and get it working like new again. In this post, we will explain how to recondition laptop batteries. Keep reading to learn more!

1. Gather your materials. In order to recondition a laptop battery, you will need:
- A laptop battery
- A multimeter
- A screwdriver
- Some sandpaper
2. Remove the battery from the laptop. With the screwdriver, remove the screws that hold the battery in place. You may need to reference your laptop’s manual for the exact location of the screws.
3. Test the battery with the multimeter. Set the multimeter to “DC Voltage” and touch the black lead to the negative terminal on the battery, and the red lead to the positive terminal. If the reading is below 12 volts, then your battery is too far gone to be reconditioned.
4. If the battery is above 12 volts, then proceed to step 5.

5. Use sandpaper to lightly sand down both ends of the battery terminals (the positive and negative). This will help create a good connection between the terminals and the leads from the multimeter.
6. Connect one lead from the multimeter to the positive terminal on the battery, and the other lead to the negative terminal.
7. Slowly discharge the battery by sending a current through it. The multimeter will show you the voltage as it drops. Keep going until the voltage reaches around 11 volts.
8. Once the voltage has reached 11 volts, stop discharging the battery and allow it to rest for 30 minutes.
9. After 30 minutes, begin charging the battery back up slowly until the voltage reaches 12 volts again.
10. Repeat steps 7-9 two more times, for a total of three cycles.
After completing these steps, your laptop battery should be reconditioned and work like new!
Benefits Of Battery Reconditioning
1. Reconditioning batteries can save you money.
2. Reconditioned batteries have a longer lifespan than new batteries.
3. Reconditioning batteries can help the environment by reducing e-waste.
4. Reconditioned batteries can be used in place of new batteries, which can sometimes be hard to find.
5. You can learn how to recondition batteries yourself, which can be a fun and satisfying project.
What Is Battery Reconditioning?
Battery reconditioning is simply the process of restoring a battery back to its full capacity. This can be done with both lead-acid and lithium-ion batteries, though the process is slightly different for each.
Lead Acid Battery
Lead-acid batteries need to have their cells balanced, while lithium-ion batteries need to have their chemistry reset. Both processes are relatively simple and only require a few tools and materials that you likely already have around the house.
How To Recondition Laptop Batteries?
The first step is to ensure that your laptop battery is unplugged from the main power source. Next, you need to remove the battery from your laptop.
Once the battery is removed, you will need to locate the positive and negative terminals on the battery. The positive terminal is typically denoted by a plus sign (+), while the negative terminal is typically denoted by a minus sign (-).
After locating the terminals, you will need to use a voltmeter to test the voltage of the battery. Most laptop batteries have a standard voltage of 14.8 volts.
If your voltmeter does not register this voltage, then your battery may be damaged and will need to be replaced. If your voltmeter does register 14.8 volts, then your battery is most likely still usable.
The next step is to use a battery charger to charge the battery back up to its full capacity. Once the battery is charged, you can reattach it to your laptop and enjoy extended use!

1. Disconnect the battery from the power source before beginning any work.
2. Wear rubber gloves to protect your hands from acid and other chemicals.
3. Work in a well-ventilated area to avoid inhaling fumes.
4. Never attempt to open or disassemble a battery pack. Doing so could result in serious injury.
5. Avoid using sharp objects or tools near the battery packs, as this could puncture the cells and cause a leak.
1. Avoid overcharging your laptop battery. Overcharging can shorten the battery’s lifespan.
2. Disconnect your laptop from its power source when it is fully charged.
3. Store your laptop in a cool, dry place away from direct sunlight.
4. Use your laptop regularly to keep the battery healthy.
5. Calibrate your laptop battery every few months to maintain accurate charge readings.
6. If you don’t use your laptop for extended periods of time, store the battery with a 40% charge to help preserve its lifespan.
7. Check the condition of your laptop battery regularly and replace it if necessary.
We hope you’ve found this guide helpful in learning how to recondition laptop batteries. It’s a process that can save you money, and it’s not as difficult as you may have thought.
