Basic Checkpoint for laptop battery (Li-ion)

Sometimes, the problem may not lie with the battery but also with your laptop. An old laptop may have numerous issues so it is recommended to check your laptop first before trying any of these 5 methods.

Freezing Method

This is one of the best methods you can find on the list. The freezing method can jump-start your dead battery and you can do this process by following a few precautions.

  • Take the battery out of your laptop and carefully seal it in a Ziploc bag.
  • Carefully place the Ziploc bag into your freezer and leave it for about 12 to 20 hours.
  • After it freezes, remove the Ziploc bag slowly and let the battery warm-up till it reaches room temperature. Cautiously, wipe away the condensed water after it reaches room temperature.
  • Reinsert your battery and charge your laptop completely.
  • After it is completely charged, let the battery drain completely.
  • Repeat the charging and discharging process at least 4 to 5 times. Unless your battery is leaking acid, you will be able to get some juice out of your laptop for a long time.

Use a Cooling Pad for Laptop

The cooling pad method works best for a lithium-ion battery and it increases the battery’s life. You may think that your battery is dying but heating could be a major issue. If you do not wish to spend money on a cooling pad, we recommend you to use your laptop only in air-conditioned rooms.

Recalibrate your battery

If your battery is on its last legs, it is most likely due to obsolescence. You can use recalibration here and it is done when your operating system is unable to figure out the remaining capacity of the battery.

You can figure out your battery’s need for recalibration when it does not completely charge or if your laptop dies sooner than you anticipated. Although different models of laptops have different calibration tools, here is a standard procedure.

Do check on the internet before following this step-by-step.

  • Charge your battery completely and leave it for 2 hours to cool down.
  • Disconnect the power and let the battery drain by running it till the laptop dies. You can set it to sleep as well.
  • Let the laptop remain switched off for at least 3 to 5 hours.
  • Switch on your laptop after that and charge it completely. Your battery is now recalibrated and your operating system will provide you with an accurate reading.

Remove Battery when Laptop is Plugged in

This method works if your laptop has an easily removable battery and you need to remove the battery when the laptop is plugged in. Some laptops do not work after the battery is removed so do this method only if your laptop works.

Your battery will get a jump-start even if it is not inside the laptop. Doing this method can increase the life of your battery as it is cool and not hot when plugged in. Although this method is quite time-consuming and annoying, you can try this as a last resort.

Unplug Laptop at Full Battery

Do not let your laptop die in this method. Unplug your laptop immediately after it reaches 100% and plugs it back in once the battery reaches below 10%. As a word of caution, do not do this method numerous times on lithium-ion batteries and charge lithium-ion batteries normally. This method will give your battery a better life cycle.
