Laptop batteries are expensive pieces of equipment, so if you have an former laptop that still works fine, who wants to shell out upward of $100 to supplant the bombardment right!? Luckily, there are a lot of ways, some technical, some interesting and some strange ones, that people have come up up with to restore dying batteries on laptops.

In this article, I'thousand going to try to listing out all the unlike ones I've read about and if I tin retrieve where I read it, I'll link back to the original source. If yous have tried to restore a laptop battery yourself, let us know your method in the comments.

Method one – The Freezing Method

I one time saw a pic where a guys' phone was about to dice, so he took out the battery and stuck in some snow, which manifestly fabricated it concluding longer! I still don't know if that's true or not, but apparently you can freeze a laptop battery and get more juice out of information technology. Here'southward the procedure very succinctly:

Footstep 1: Take your battery out and place it in a sealed Ziploc or plastic bag.

Step 2: Become ahead and put the bag into your freezer and leave it there for virtually 12 hours. Some people suggest leaving information technology for longer, only I wouldn't exit it for more than than 24 hours.

Step iii: Once y'all accept it out, remove the plastic bag and let the battery warm up until it reaches room temperature. Exist certain to wrap it in a towel and wipe away any condensation as it warms up.

Step 4: Reinsert the laptop bombardment and charge it completely.

Pace 5: One time charged, unplug the ability and allow the battery drain all the style down.

Now repeat steps iv and 5 at to the lowest degree iv times: charge all the mode to full, then discharge completely. That should be information technology! Unless your battery is leaking acrid, you should get some kind of crash-land in the battery life.

Notation that you should only perform this on NiCD or NiMH batteries. If you try this on a lithium battery, information technology'll make the battery life worse. Unfortunately, there is no mode to restore a lithium battery. Y'all'll have to find your laptop specs to encounter what kind of battery yous have. For lithium ion batteries, yous can't restore, merely you lot tin peradventure extend the life of a battery. Read method two.

Method 2 – Absurd Your Estimator

If you take a lithium ion based battery, you tin increase it'southward life by making sure your laptop is cool. If you take a laptop that gets really hot, it can damage the battery and cause the shortness in battery life. I take an old Sony VAIO laptop and I saw a significant increase in laptop battery life when I bought a laptop cooling pad off Amazon. Yous can get one like this for $xx.

You may think your battery is on it's terminal leg, simply it could simply be that it's getting likewise warm and therefore loses charge faster.

Method three – Recalibrate Your Battery

With most newer batteries, this is no longer necessary, simply if your battery is dying, then it's probably a pretty one-time battery. In that instance, you may do good from a recalibration. Recalibrating a battery is done because sometimes the operating organization cannot figure out how much chapters is left in the battery. This can happen if the laptop is e'er plugged in or if the battery was never let to die all the way.

You can tell whether your battery needs calibration if your battery never charges to 100% (say only to 95%) or if the OS says you take 35 min of battery remaining, but the reckoner dies either much sooner or much later. A lot of manufacturers have released scale tools for specific laptop models, so get-go perform a Google search with your reckoner model + battery calibration. Here's an example tool from Sony.

If you accept to manually recalibrate a battery, the procedure is pretty straight-forward:

Footstep 1: Charge your battery to 100% or to whatever max percent it can achieve and leave information technology there for almost 2 hours to absurd downwards.

Pace ii: At present disconnect the power and let the battery drain. There seems to be ii views about how to do this. Yous tin can either let the battery run down all the mode until the laptop dies or you can gear up it so that information technology goes to sleep or hibernates effectually 3 to 5%. Either mode, you want to make sure the display stays on until it either dies or goes to sleep.

Step 3: Allow the computer remain turned off for anywhere between three to 5 hours.

Step 4: Turn it back on and let information technology charge all the mode to 100%.

That's pretty much information technology. Now the figurer should exist giving yous a more than authentic reading of the bodily capacity of the battery.

Method four – Remove Battery When Plugged In

If you lot have a laptop with a removable battery, you can try to remove the battery during the times you lot have it plugged into the wall. You may have to exam this considering some laptops don't work properly with the battery removed. However, if the laptop is running fine and it'southward connected to a power source all the time, it may help to only remove the battery.

The chemical reactions will go on to occur in the bombardment regardless of whether or not information technology's in the laptop, but it could increase the life of the bombardment. Since the battery is absurd and not hot when plugged in, you'll get more life out of your battery.

Of class, you'll need to make sure you're not living in an expanse where the power goes out because your figurer will die immediately and you'll lose whatever data. This method is likewise time-consuming and abrasive and something nearly people won't practice. The concluding method below may be the best.

Method 5 – Unplug at Full Battery

The concluding option you can try is to let the battery charge to 100% and so simply unplug the figurer. When it gets close to dying, i.east. less than 5%, become ahead and plug it in and let it charge up. Withal, this could reduce battery life on newer lithium ion batteries, so for those batteries it's suggested you simply let the battery level drop to 35% to 45% and and so charge it back up to 75% to 85%. Sounds crazy, but evidently that volition give you the best battery life because it won't use up every bit many accuse and recharge cycles.

Again, this method also requires a bit of work, but information technology's worth a try if you actually want to increase your battery life. Take you used any other methods not mentioned here to increase your laptop battery life? If so, let us know in the comments. Enjoy!
