 Is it possible to recondition an old battery?

It is possible to recondition a battery, provided you know the design and construction. You should be able to diagnose and detect the exact problems in detail. Then you should know the various probabilities of troubleshooting.

The first parameter you should test is the responsiveness of the battery. The minimum volts you should get from a dead battery are stated to be 10 volts.

According to the experts, it may not be possible to recondition if the value is lesser.

How to recondition an old laptop battery?

The first step is to check the problem with the laptop battery.

Is it completely dead? Is the voltage too low? Is it responding to multi-meter testing? What is the maximum voltage? These are some of the aspects you have to consider.

Step 1

The first step is to install the battery into an adapter or into the laptop. Then it is possible to check the output and decide on the remedial measure.

You can charge the battery for at least three to four hours. You can measure how much of charge it is able to retain after you disconnect the charger.

Step 2

You have to run the laptop until the battery is completely dry. It gives you an idea about how long the battery can last on a single charging.

Make sure you have disabled the hibernate option in the laptop operating system.

Step 3

Remove the battery and wrap it using a plastic cover. Make sure it doesn’t get exposed to the external environment. Then you can place in the refrigerator for about 15 hours.

Once you take it out, it will be restored to the working condition.

You can repeat the procedures whenever you face problems with the battery.

It is possible to use the method for at least six months without having to replace your battery with a new one.

Step 1

Remove all the liquid in the battery and clean it using a cloth or a brush. Make sure you wear the protective gloves.

Use a scrubber to remove all the rust and dust from the terminals. You can use a mixture of vinegar and salt to clean.

Sometimes the terminals will have corrosion. It may become difficult to clean them but you can use a steel brush to remove.

Make sure you don’t damage any of the parts while brushing. Similarly, you can clean the battery exteriors using vinegar and salt solution.

Step 2

Now you need to clean the inside of cells. For that, you need distilled water and washing soda.

You can mix 250 grams of baking soda in 2 liters of the liquid.

Fill all the cells completely. Now you have to cap all the cells and wait for 20 minutes.

Now, you have to shake the battery for about a minute. You may have to repeat the procedures three to four times.

Step 3

Empty the cells and let the battery dry for 20 minutes. Then you have to prepare a solution of distilled water and Epsom salt.

You can use the same formula which you used for baking soda. You can fill the cells with the solution fully.

Fasten the cell caps and wait for 30 minutes.

Step 4

Charge the battery for its complete capacity. Make sure you keep the cell caps open while charging.

Once complete, you can put the caps back on and start using the battery again.

How to Recondition Lead Acid batteries

You can repair and refurbish most of the cells in your old lead-acid battery through cleaning and restoration procedures.

However, some of them may be out of working condition.  You may have to replace them if required.

Step 1

Use a multi-meter to test the voltage from each cell. It should be at least 10 volts.

If any cell is generating a lesser value, it is better to replace it.

Step 2

Pour out the acid in the battery and clean the interiors. Use a brush to remove the dirt, chemicals, and rust. Remove the corrosion with the help of a brush.

Make sure you are wearing the protective mask and the gloves.

Step 3

Use a combination of distilled water and washing soda. You can mix 250 grams of baking soda in 2 liters of the liquid. Fill all the cells completely.

Now you have to cap all the cells and wait for 20 minutes. Shake the battery for a minute to dissolve all the remaining dirt and dust.

Step 4

Let the battery dry for about 20 minutes. Then you have to De-sulfate the battery.

You can use a chemical that is available from a chemical lab near you. Immerse all the cells and wait for 48 hours.

Step 5

Remove the de-sulfate chemical and clean the battery again. Let it dry for 20 minutes. Then you can refill the cells with the lead-acid solution and close the caps.

Dry the exterior parts and charge the battery. Now you can start using it.

Generally, a refurbished car battery can last for four to five years, depending on the present condition. You have to make sure of using the right procedures. For example, the ones explained here are based on experiments and practical implementation.

Deep cycle car batteries could be complex to refurbish. But they can have a long life after reconditioning. Mixing of the chemicals and distilled water has to be in exact proportions in order to make the program a success.

You have to ensure the removal of rust and corrosion completely. In some cases, it may not be possible to brush out the corrosion. Then it is a good practice to replace the corroded parts rather than trying to repair them.

You have to understand the architecture of the battery you are trying to recondition. You have to know the basic terminologies like the voltage, watts, ampere, and other related terms. You should also have basic knowledge of the battery names.

Conclusion

It is possible to recondition any of the batteries at home using simple methods.

The procedures for dry batteries used in cell phones and other appliances will change.

You need to take all the safety measures like gloves, safety clothes and masks before trying the reconditioning procedures.
