Restoring Batteries: Old Battery, Epsom Salt and Working

APR 14, 2021   Pageview:109

You’re cleaning up the house and are currently rummaging through the room that stores unused objects. Then, you come across an old battery. Wait, don’t throw it away! The battery might be useful for the household items in your house! If the battery can’t be used, don’t worry! We will tell you how the process of restoring batteries here, especially if you are using Epsom salt.

Some people might think that restoring old batteries is a waste. Believe it or not, restoring old batteries might do us some good. When you restore old batteries you:

1.Save money. That’s right, if you restore old batteries, there’s no need to purchase extra batteries anymore since you’ll be able to use them for your stuff

2.Get new experience. When you restore old batteries, you’ll get new information on how to restore the battery and other things related to it.

3.Lessen earth waste. By using old items, you won’t need to purchase new batteries, lessening the waste that will be thrown away. While you cannot reduce the current trash, it definitely prevents yourself from creating another battery waste. We have had enough of them.

Restoring old batteries is not that hard. However, different batteries need different ways of restoration.

Restoring Laptop Batteries

There are several ways to restore laptop batteries. The first method you can do is using a freezer and a plastic bag. This method is best used when there’s no leakage on the battery:

1.Take out the battery from the laptop.

2.Place the battery into the plastic bag.

3.Put the battery inside the freezer.

4.Wait for 12 hours, then take out the battery from the freezer.

The second method to restore the battery is by resting them. Here are the steps to do it:

Low Temperature High Energy Density Rugged Laptop Polymer Battery Battery specification: 11.1V 7800mAh -40℃ 0.2C discharge capacity ≥80% Dustproof, resistance to dropping, anti - corrosion, anti - electromagnetic interference

1.Charge the laptop until it reaches one hundred percent.

2.Leave the laptop on stand for around two to three hours

3.Unplug the laptop and let the battery drain until it’s completely empty

4.Leave the laptop for 5 hours-ish.

5.Charge the battery again until it’s full.

Restoring Hybrid Batteries

Restoring hybrid batteries on car is not that hard, but it does require some extra attention since you might miss a spot or two if you’re being careless. Here are the steps to restore hybrid batteries:

1.Take out the battery carefully and remove the protective rubbers of the cap.

2.Remove the caps

3.Fill the battery with  distilled water and recharge it for at least one hour.

Not so hard, isn’t it?

Restoring Nicad Batteries

Yes, restoring nicad batteries have their own steps. Here are the things you should do to restore them. The process might take a while, but the result is definitely worth it:

1.Connect the capacitor to a battery holder and a switch.

2.Connect the cylinder and the cylinder wires together using the battery holder and the switch.

3.Make sure that you’re doing this on a ground that’s not surrounded by other objects. The wires should be insulated too.

4.Put an alkaline battery in the capacitor and the nicad battery into the holder.

5.Flick the switch. While you do that, make sure you check the LED too.

6.Do the fifth step again until you hear a noise.  The noise indicates that the sulfur crystal is destroyed. If you hear the noise, then the battery is all good now.


Restoring Lead Acid Batteries

Last in this section, we have a method to restore lead acid batteries. Here is a method to do it:

1.Take out the battery and its protective rubber.

2.Once the battery is removed properly, take out its cap.

3.Check if the battery is low on distilled water. If there is no distilled water, fill it up with distilled water.

4.Check the volt of the battery using voltmeter. It is considered charge when its volt is between 13 to 14 volt.

If the method above does not work, you can try this method. This method is pretty aggressive, so make sure you do it carefully:

1.Purchase an acid pack.

2.Remove the acid inside the battery and fill it with new distilled water.

3.Charge the battery for 10-12 hours (slow charger) or 6 hours (fast charger).

There are many ways you can restore a variety of old batteries. Which one of the restoration method will you do?

Restoring Batteries With Epsom Salt

If you want a more traditional method, you can try restoring old batteries using epsom salt. The process is pretty dangerous if it’s not done correctly, so make sure you wear insulated gloves and protective goggles when you do it. The steps are:

1.Disconnect the cable for positive grounds first, then disconnect the cable for the negative terminal. Once you’re done, remove the battery.

2.Heat up 1/2 quart of distilled water and pout 7 to 8 ounces of epsom salt inside it. Let the salt dissolve.

3.Take out the remaining liquid inside the battery. Make sure the liquid is neutralized first by using baking soda. Once you’ve taken out the neutralized liquid, pour it down the drain and while running the water.

4.Take out a plastic funnel and pour Epsom salt into each battery cell until it’s full. Shake the battery gently so that the Epsom salt is distributed evenly.

5.Once you’re done, put the caps back on.

6.Connect the cables again. This time, connect the positive side first then the negative side. 

7.Charge the battery. Make sure you have VOLT/AMP on the setting.

8.When the battery is fully charged, that’s when the battery is desulfated.

The process is not complicated, but it does require extra work. But don’t worry, you will be accustomed to it once you’ve done it several times.

Does battery reconditioning really work?

Battery reconditioning does work, since it’s bringing the healthy part of the battery back. It’s not really “reviving” since we are basically bringing its healthy part back and using it to the most. When the battery does not work after reconditioning, only then it’s when the battery is completely dead, giving us the signal to actually purchase a new battery. But if you can recondition it, then why not?
