Laptop batteries are costly and original ones hard to come-by this days. Is your laptop battery not lasting as it ought to be? There are a lot of ways, some technical, some interesting and some strange ones, that people have come up with to restore dying batteries on laptops. In this article, we are going to list out methods of Laptop Battery refurbishment . In other words; how To restore laptop battery
Methods of Laptop Battery Refurbishment
The Freezing Method
Laptop battery can be restored by stuck in some snow to get more juice out of it. Here is the procedure to follow in doing that:
Step 1: Take your battery out and place it in a plastic bag or sealed Ziploc
Step 2: Go ahead and put the bag into your freezer and leave it there for about 12 hours.
Step 3: Once you take it out, remove the plastic bag and let the battery warm up until it reaches room temperature. Be sure to wrap it in a towel and wipe away any condensation as it warms up.
Step 4: Reinsert the laptop battery and charge it completely.
Step 5: Once charged, unplug the power and let the battery drain all the way down.
Now repeat steps 4 and 5 at least 4 times: charge all the way to full, then discharge completely. That should be it! Unless your battery is leaking acid, you should get some kind of bump in the battery life.
Note: Know it that you can only perform this on NiCD or NiMH batteries. If you try this on a lithium battery, it will make the battery life worse. Unfortunately, there is no way to restore a lithium battery. You’ll have to find your laptop specs to see what kind of battery you have. For lithium ion batteries, you can’t restore, but you can possibly extend the life of a battery.

Cool Your Computer Method
If you have a lithium ion based battery, you can increase it’s life by making sure your laptop is cool. If you have a laptop that gets really hot, it can damage the battery and cause the shortness in battery life. So, you need a laptop cooling pad to keep you laptop cool at all times. See the cooling pad for yourself-
You might have concluded that your battery is bad, but it could simply be that it is getting too warm and therefore loses charge faster.
Recalibrating a battery is done when the operating system of a computer set cannot figure out how much capacity is left in the battery. This can happen if the laptop is always 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 have 35 min of battery remaining, but the computer dies either much sooner or much later. A lot of manufacturers have released calibration tools for specific laptop models. To manually recalibrate a battery, the procedure is simple straight-forward:
Step 1: Charge your battery to 100% or to whatever max percentage it can reach and leave it there for about 2 hours to cool down.
Step 2: Now disconnect the power and let the battery drain. There seems to be two views about how to do this. You can either let the battery run down all the way until the laptop dies or you can set it so that it goes to sleep or hibernates around 3 to 5%. Either way, you want to make sure the display stays on until it either dies or goes to sleep.
Step 3: Let the computer remain turned off for anywhere between 3 to 5 hours.
Step 4: Turn it back on and let it charge all the way to 100%.
Now the computer should be giving you a more accurate reading of the actual capacity of the battery.
Method 4 – Remove Battery When Plugged In
If you have a laptop with a removable battery, you can try to remove the battery during the times you have it plugged into the wall. You may have to test this because some laptops don’t work properly with the battery removed. However, if the laptop is running fine and it’s connected to a power source all the time, it may help to simply remove the battery.
The chemical reactions will continue to occur in the battery regardless of whether or not it’s in the laptop, but it could increase the life of the battery. Since the battery is cool and not hot when plugged in, you’ll get more life out of your battery.
Of course, you’ll need to make sure you’re not living in an area where the power goes out because your computer will die immediately and you’ll lose any data. This method is also time-consuming and annoying and something most people won’t do. The last method below may be the best.
Method 5 – Unplug at Full Battery
The last option you can try is to let the battery charge to 100% and then simply unplug the computer. When it gets close to dying, i.e. less than 5%, go ahead and plug it in and let it charge up. However, this could reduce battery life on newer lithium ion batteries, so for those batteries it’s suggested you only let the battery level drop to 35% to 45% and then charge it back up to 75% to 85%. Sounds crazy, but apparently that will give you the best battery life because it won’t use up as many charge and recharge cycles.
Laptop Battery Refurbishment requires a bit of work, but it’s worth a try if you really want to increase your battery life.
