You can learn how to fix a laptop computer battery.Computer batteries need to be replaced every 2 to 3 years for optimal performance.If you discharge your laptop's battery completely, it will damage the battery further.
Step 1: Make sure you don't own a Li-ion battery.
If you want to use this method, your battery needs to be either NiMH or NiCD.The battery will likely be destroyed if you do this method with the wrong battery.Many modern Windows computers use the same type of batteries as the Macs.If you perform this process on a computer with a non-removable battery pack, you will either have to remove the battery or freeze the whole computer, which will ruin your computer.
Step 2: Turn off your laptop.
Your laptop needs to be completely turned off and unplugged before you can remove the battery, as failure to do so may result in an electric shock.
Step 3: The battery should be removed.
If your laptop has a battery release button on the bottom, you can unclip the battery from there.
Step 4: The bag has the battery in it.
This will add a buffer between your battery and the second bag.
Step 5: The battery should be placed in a bag.
This will make sure the battery doesn't get damp.If you use a regular plastic bag, the battery may accumulate in it.
Step 6: The battery can be left in the freezer for 10 hours.
The battery can be restored at least part of the time.The battery can be left in for as long as 12 hours, but if you leave it in any longer than that it may leak.
Step 7: The battery needs to be charged.
Once your battery has spent enough time in the freezer, you can remove it, dry it off, and then plug it back into your laptop.You should be able to charge the battery there.
Step 8: Know when to use it.
If your computer's battery indicator is no longer displaying the correct amount of charge, you'll want to change the battery on your laptop.If your battery indicator says you have 50% charge but your computer shuts down, you should change it.
Step 9: The battery needs to be charged to 100%.
When your battery reaches the "fully charged" point, keep your computer's charge plugged in.
Step 10: Plug your laptop back in.
The side of the cable that has the charger on it should be removed from your computer.Plugging the wall sockets side of the charger back in while the laptop is connected could damage the computer.
Step 11: The battery on your laptop needs to be completely drained.
It is possible to keep your computer turned on until the battery life runs out, but streaming video or running another process will speed up the draining of your battery.
Step 12: For the next 3 to 5 hours, leave your laptop unplugged.
This will make sure that the battery's phantom charge is gone before anything happens.You should skip this step for a battery.
Step 13: Charge the battery.
Plug the computer's charge back in.The battery should be adjusted once it reaches 100% again.
Step 14: If your battery is draining quickly, you should perform this method.
If your laptop's battery is suddenly draining faster than it used to, performing this method once may fix the problem.The lifespan of most laptop batteries can be reduced by 30% if you do this method too often.
Step 15: Plug your laptop back in.
The laptop's charging port should be removed.Plugging the wall sockets side of the charger back in while the laptop is connected could damage the computer.
Step 16: The battery on your laptop needs to be completely drained.
It is possible to keep your computer turned on until the battery life runs out, but streaming video or running another process will speed up the draining of your battery.
Step 17: Take your laptop with you for around 3 hours.
This will make sure the battery is dead before you start.If you have a battery, skip this step.
Step 18: Charge the battery.
Plug the computer's charge back in.If you leave your laptop off for a while, the process will be more effective.
Step 19: The battery can be charged for 48 hours.
You can use your computer during this time, but make sure it is plugged in for at least 2 days.If you do this, you will ensure that your battery is fully charged, which will lead to an increase in battery life.
Step 20: Do not discharge your battery lower than 20%.
If you don't charge your laptop's battery all the way, the life of the battery will drop by 30% after between 300 and 500 discharges and by 50% after 1000 discharges.You should only ever discharge your laptop's battery to 20%.Before you hit 70% battery life mark, this will allow for over 2000 discharges.To keep your battery in good working order, let it discharge 20% of the time.It will last longer if you leave your laptop plugged in all the time, because the chemicals inside the battery get mixed up.
Step 21: Make sure your computer isn't too hot.
Damage to the battery itself can be caused by heat.Make sure the laptop's vents are free of obstructions if you're running it in warm environments.You may want to place the laptop on a cool surface such as a desk, as using your laptop in your lap may prevent proper circulation.
Step 22: Store batteries in a way that protects them.
If you're going to be placing a laptop in storage, you can make sure that the battery lasts the longest by storing it at full charge in a location that's between 20 and 25C.For several months, batteries can be stored in this condition.Never store batteries that aren't 100% charged.
Step 23: It's a good idea to remove the battery when editing or gaming.
If your laptop has aremovable battery, you can prevent heat damage to the battery by keeping it plugged into the computer's charging port and performing system-intensive actions such as gaming or video editing.If you frequently use your laptop for high-power activities, heat can shorten the battery's lifespan.
