How to Recondition a Laptop Battery An easy, step-by-step guide to recondition dead laptop batteries at home. Written by Kevin Miller. NiCad Nickel Cadmium These batteries have an average life cycle of 1, before dying out.

They require a periodic full discharge and charge maintenance cycle. This battery type loses 20 percent of their capacity every month when kept in room temperature. Each time you plug off its charger, it loses 10 percent of its capacity within 24 hours.

In comparison with the other two batteries, this one has a mid-range useful life. However, with proper maintenance, it can last longer than the two different battery types. Perhaps, this battery has the shortest useful life compared to other types. It can only last for around cycles of charge and discharge. Similar to NiCad, this battery type needs to have a maintenance cycle of full discharge and charge. If not properly maintained, you can have cycles instead of Unlike NiCad, this type does need to be fully drained off with charge.

Unplugging it for a while can reasonably increase the life cycle of the battery. Despite recent improvements to lithium-ion technology, most batteries can only withstand a certain number of charge cycles before their capacity starts to deteriorate rapidly. Of course, there are a few steps you can take to combat the issue, but none of these will help if your battery is already dead.

So, is it possible to jump-start a dead laptop battery? Well, yes. We look at three different methods and give each one a score out of 10 for ease and effectiveness.

If your computer has a nickel-metal hydride NiMH or nickel-cadmium NiCd battery, you could try freezing it. If you have a lithium battery which covers all Macs and most new Windows computers , do not try this method. It might sound fanciful, but this method is scientifically proven to work. By freezing a battery, you're accomplishing two feats:. Note: If your battery is exceptionally old, all the electrons have probably leaked away, and this method will not work.

To begin, turn off your computer, disconnect it from the wall socket, and remove the battery from your machine. Be warned that if your battery is not removable, taking apart your computer to get it out will void the warranty.

Next, place the battery inside a cloth bag, then put the cloth bag inside a sealable Ziploc bag. Do not skip the cloth bagit adds an essential layer of insulation.

And make sure you use a Ziploc bag. A regular plastic grocery bag will allow moisture to seep in, potentially destroying your battery for good. Put the Ziploc bag in the freezer for 10 hours. After the 10 hours have passed, let the battery naturally warm up to room temperature before putting it back into your computer. You will be measuring the voltage of the pair. Get your charger. Determine which wire is the positive and which is the negative. Often there is a white or grey line on one of the wires.

If not, just use a bit of tape. Now measure with your multimeter. If the voltage displayed is a positive number, then the red tip is touching the positive and the black tip the negative. If the voltage displayed is negative, then it's the other way around. Yes, I am measuring That's because I didn't have a low voltage charger laying around, but if you do this, you may damage your cells.

I didn't care a whole lot, though, and I haven't noticed any damage even though I've done this twice now. Put your positive wire on the positive end of the battery and the negative on the negative. Recharge for a minute. Then wait seconds before measuring. That is because the voltage in the cells will fall when you stop charging them. Here, I have already increased the voltage quite a bit.

When you think you have finally hit the correct voltage, wait half a minute and remeasure to make sure that it doesn't need a little more. Push the cells back together and put them down the battery cover as shown. Make sure, that the circuit board is all the way in you can't do it wrong.

Put back the lid, it will pop in. Put back the sticker and if it doesn't stick it really should , just use some transparent tape or glue. Push it back in the laptop and push the lock into the locked position, which is towards the battery. Now, grab one of the wires and close the pliers on them, but don't cut. Sort of pull away the insulation. You may need to use your fingers to pull it off completely. Twist the cable. That is how you fix your laptop battery for no money at all and in only half an hour!

You may consider changing the cells, though, as dying this way is an indicator of a bad cell. There are great instructables for that. And who knows, maybe it will keep working forever? Mine kept working for half a year before it needed a new treatment but hey, how else would one spend a Saturday evening, am I right? Question 4 months ago on Step So sorry,i spread all six batteries instead of what you're did , I been told that they must be bunch together again and I can't attach them by soldering and I think it'll be more chipper if I buy a new one?

I'm a bit confused, I want to build a battery for My drill There's also one more thing You might find it's at full voltage. You might also get some crystalized electrolyte that holds it open. LIion cells dump their full mAh amperage into a dead short. I had one cell burn a AWG solid brass pin in half. Reply 4 months ago.

I already broke it badly with my finger in it , I was thinking about making or buying a new one, now I have already sixteen li--ion battery's , what sould I do? It should never be too late, as long as your charger works.

The percentage is normally just the percentage on your battery and is not an indication of the power your computer receives directly from the charger. Not Helpful 0 Helpful Turn the system off and make sure the battery is well placed in the battery bay. Try removing the battery and reconnecting it. Not Helpful 3 Helpful My battery is "plugged in, charging" but the charge is zero percent. What could be wrong? Not Helpful 34 Helpful My laptop battery is totally dead, not even turning on.

I have some important data that I need to copy. It may take not more than 15 minutes. What should I do? You can power any laptop without battery by using its charger. It will provide the same energy as its battery. Not Helpful 14 Helpful Replace the battery. If you want to use the laptop on the AC, remove the battery. The laptop will run just fine without a battery on the AC. Plug in the battery only as needed to charge it.

Don't store the battery in a discharged state. Charge it first. Not Helpful 4 Helpful If your battery is dead and this method doesn't work, you can remove the battery and replace it with a new one. Not Helpful 4 Helpful 7. I plug the charger but it won't charge and turn on. Please help me to find a solution. If your battery won't charge that probably means it is dead or the charger is somehow broken. Not Helpful 1 Helpful 7. Include your email address to get a message when this question is answered.

If your battery isn't charging, check the AC adapter and the charging port. These tend to wear out more quickly than the battery itself. You can get a new power source online or from an electronics store.

If this happens, you can usually take your battery pack into a tech department in order to have a professional "wake up" the battery with a power supply.

If your laptop battery is dead and you aren't able to get a new one right away, plug your laptop in and use it like a desktop until you can replace the battery. Don't put your laptop battery into the freezer without securely bagging it, as it may attract water and ice that will cause damage.
