You’ll Save Money

It is cheaper to recondition your laptop battery compared to buying a new battery or getting a new laptop. This makes it the perfect solution if you are working with a tight budget or trying to save money.

It’s Good for the Environment

The environment may be the last thing on your mind if you are facing battery problems, but when you recondition your laptop battery, you are lowering the amount of battery waste produced, which would be very beneficial for the environment.

Enjoy Reliable Power

When you know how to recondition laptop batteries, you can enjoy having reliable battery power once more. And you can use your laptop for hours, even without charging it.

Types of Laptop Battery

There are various kinds of laptop batteries: NiCd, NiMH, and lithium-ion. You first need to know what type of battery your laptop has before finding out ways to recondition it.

Lithium-Ion (Li-Ion battery)

This lightweight battery is a top choice for laptop owners because it offers tons of advantages. It has a bigger power density, as well as no memory effect. This means that they do not lose the capacity of being fully charged when they are not 100% drained. It also has a good storage life. The only drawback of Li-ion batteries is their high replacement cost.

Nickel-Cadmium (Ni-Cd battery)

This type of laptop battery has a memory effect, which is a chemical reaction that happens when the battery is not fully discharged before you charge it. It also needs to be properly maintained and stored.

Nickel-Metal Hydride (NiMH battery)

For this type of laptop battery, you need to be careful to only leave it half discharged. It has a large power capacity, but it has a lower lifespan compared to Lithium-Ion batteries. This battery is more common with older laptop models.

How to Recondition a Laptop Battery

Here’s how to recondition laptop batteries.

Lithium-Ion Battery Reconditioning

The steps for reconditioning a Lithium-ion laptop battery are as follows:

  • First, turn off your laptop and locate the battery chamber. Then, use a voltmeter to measure the battery level. If the reading shows 1.5 volts, the battery may be in sleep mode. The good news is many lithium-ion batteries come with a boost, recovery, and wake-up feature to get it back into power from sleep mode.
  • After “waking up” your battery, use your charger to give your battery a full charge.
  • When it finally reaches 100 percent of charge. Then, switch on your laptop and keep it on until it discharges completely.
  • Place the Li-ion battery in an airtight bag to prevent it from getting wet and freeze it for around 24 hours. Take it out of the freezer and let it thaw for up to eight hours to bring it back to room temperature before using it.
  • The next step is to fully recharge your laptop to its maximum 100 percent capacity once more.

NiMH Battery Reconditioning

Discharge and recharge:

To recondition a NiMH Battery, give it a full charge and leave it on for around 3 hours. Then, leave your laptop unplugged until the battery is completely drained and it turns off. Let it sit for around 5 hours, then recharge it until it’s full.

Freezing method:

You can also use the freezing technique. To do this, seal the battery in an airtight bag and put it in the freezer for around 24 hours. Make sure no moisture penetrates the bag. Remove it from the fridge and let it warm to room temperature. Make sure it is completely dry and replace it in your laptop, then charge it again until it reaches 100 percent.

Ni-Cd Battery Reconditioning:

To recondition your Ni-Cd laptop battery, discharge it until it only has enough power to avoid losing data. Charging the battery allows it to recover the memory and management functions. Constantly recharging this laptop battery will interrupt memory function and decrease the time your laptop can hold a charge.

Let your laptop’s battery charge deplete completely before you charge it. You may need to do this multiple times if your battery is already well-used.
The freezing technique also works for this type of battery.

Warnings When Reconditioning a Laptop Battery

Before you exercise the tips on how to recondition laptop batteries, you first need to know the precautions you need to take when doing this.
  • If you have NiMH or Ni-Cd batteries, calibrate them at least once a month to make sure you don’t cause circuit connection damage in the battery and your laptop. However, calibrating is not recommended when it comes to lithium-ion batteries.
  • Your laptop should also be turned off before you remove its battery to avoid electric shock.
  • Do not perform the freezing technique on a non-removable battery since it can void your laptop’s warranty and freeze the unit. For the freezing technique to work, it is recommended to place your battery in a cloth bag before the ziplock bag, so there is a buffer. Do not use regular plastic bags since it may only cause moisture to accumulate in the bag.
  • When working with batteries, you should always wear safety goggles.

How Long Does Reconditioning Batteries Take?

The time it takes to recondition your laptop battery varies from one person to another. This is because it depends on factors such as:

  • Your skillset.
  • The type of battery that you have.


Tips to Maintain Your Laptop Battery

It can be a hassle to constantly recondition your laptop. Proper battery maintenance is critical to ensuring longer laptop battery life, to help you keep your battery’s life intact, we’ve rounded up some tips below.

Try a Laptop Cooler

For a more long-term solution, set up a laptop cooler. This will help prevent your laptop from heating up to a point where it damages its battery. It can also help you save money since batteries perform better in cooler temperatures.

Do Not Use Knockoff Chargers

You may think you’re saving money with a fake charger, but it might be doing you more harm than good. Fake chargers do not meet safety regulations and may cause electric shocks and fires.

Charge It Before It Is Fully Drained

Never drain your laptop battery below 20% since a low charge will strain your battery and reduce its charging capacity.

Do Not Leave It Uncharged for a Long Period

Draining your laptop battery is inevitable. However, charge it as soon as you can, and do not leave it drained since it is unhealthy for the battery.

Prioritize Your RAM

If you do heavy tasks on your computer, make sure it has enough RAM. This is a more effective way to retrieve data. When RAM is being used instead of your hard drive, your battery won’t be drained as fast.
