It is common knowledge that batteries must be replaced at some point. They lose their charge, become less efficient, and in certain cases, the case bulges, causing serious harm to the device or machine they’re in. This, however, is only true for throwaway and low-quality batteries. In the vast majority of cases, it is possible to recondition batteries to make them fully functioning again.
It’s a process called reconditioning, and it involves a variety of tactics and ideas, which we will reveal in this post so that you may learn how to recondition your batteries and make them completely functioning once more.
You will not only receive a new battery, but you will also save money and avoid pollution. We can lessen the impact of obsolete batteries on the environment by 50% by doing so. As a consequence, the environment will be healthier, and you will not have to pay a large sum of money for a brand new battery, which is highly expensive.
Why should you recondition dead batteries?
Batteries, as you may be aware, can be quite costly to replace. Whether it is laptop batteries, auto batteries, or the non-replaceable batteries found in today’s phones, they’re all extremely expensive to repair and may not even get cheaper as the gadget gets older. In some circumstances, replacement batteries for obsolete gadgets aren’t even available because they’re no longer in stock.
Reconditioning batteries allows you to preserve the function of your batteries and even renew them so that they work as well as new, allowing you to save money while still getting plenty of charges. Additionally, this is also better for the environment because batteries are difficult to recycle and frequently end up in garbage bins, seeping poisons into the environment and wreaking havoc on the planet’s health.
Finally, reconditioning is simply more convenient. Imagine never needing to buy a battery for a major device again because you can recondition it yourself. You’ll save money, time, and, most importantly, a lot of stress in the future. Outside of putting in a little work, there are essentially no negatives to reconditioning your batteries, and you’ll learn that it’s rather simple to do so in this article.
Are there any risks when reconditioning dead batteries?
If you handle batteries wrong, they can be highly harmful, especially if you don’t have the proper safety equipment. To prevent the battery acid from leaking out and burning your skin or anything else it comes into touch with, you must wear safety glasses and gloves.
Under certain circumstances, batteries can potentially explode, particularly if they are mishandled and treated badly. If you begin reconditioning a battery and discover that it is cracked, leaking, or broken, you must discard it as soon as possible. It’s an unsafe battery at that point, and you should dispose it because you can’t fix it in that situation.
Finally, a battery should not be reconditioned more than three or four times. Reconditioning a battery can be a terrific way to extend its life, but it will ultimately wear out, and each time you recondition it, you will see diminishing rewards. If you keep working on a reconditioned battery, it will last several years, but it will eventually deteriorate, and reconditioning will wind up damaging the battery rather than helping it.
Types of batteries that can be reconditioned
These rechargeable batteries are becoming increasingly popular. However, they are more expensive than regular battery types. A lithium-ion battery can be reconditioned in several ways, including entirely discharging it and charging it or freezing the depleted battery for 24 hours and then charging it.
Nickel based batteries
When nickel-based batteries are recharged before they are entirely dead, they have performance concerns. Reconditioning is required to restore performance, which necessitates applying high voltage to the battery terminals.
Lead Acid car batteries
Another rechargeable battery that is superior to NiCad is the Nickel Metal Hydride. Deep charge cycles are required to recondition a NiMH rechargeable battery and restore its performance.
AGM and Gel Type Batteries
Because nothing flows out if the shell fractures, these batteries are safer than lead-acid batteries. The easiest technique to recondition a gel battery is to discharge it entirely and then slowly recharge it.
How to recondition a dead car battery
The methods to reconditioning your car battery are not difficult. Because the battery is so enormous and the equipment are so easy to come by, the battery reconditioning doesn’t take long. In reality, by performing this simple activity, you can easily extend the battery’s life and reduce the number of times you need to replace it.
Equipment needed when reconditioning dead batteries
- Distilled water,
- Steel wool.
- Plastic funnel.
- Protective clothing and apron.
Step 1: Adequately prepare your battery
You must clean the battery terminals before you begin, and you must do so while wearing gloves. You can have a lot of corrosion on the posts, which needs to be scraped off before the battery can be reconditioned. You should familiarize yourself with the various components before getting started because each battery type may have a different size and post arrangement.
Blend baking soda and distilled water until runny paste forms. Apply it to the posts and wipe the area with steel wool. If there is difficult-to-clean corrosion on the posts, you can scrub them with a toothbrush. Don’t be startled if the mixture foams up; this simply means it is working. Using a little more baking soda and water, clean the spot.
Step 2: Check the battery voltage
Check the battery using your voltmeter. These are inexpensive to buy and simple to operate. Connect the terminals to the voltmeter. If it’s less than 12.6V, reconditioning your car battery can help it last longer.
Step 3: Empty the battery
Now is the time to put your goggles on if you’ve not. If they’re not chemical-resistant, you could get burned by the battery acid. Gently pry open the battery caps with your screwdriver. They should easily come off if you open them gently. Take your plastic bucket so you can pour the acid into it.
Make sure the battery is always slanted away from you when you pour the acid into the bucket. Take your time so you don’t have to deal with any spills. After you’ve emptied the battery cells, you can stand it up again. To neutralize the old acid, add half a pound of baking soda to your bucket.
Step 4: Clean the cells
When the cells are empty, mix half a gallon of distilled water with half a pound of baking soda. After you’ve mixed everything, pour some into each cell using your plastic funnel. Put the caps on the battery and shake it to clear out the insides after they’re full. Although the battery will be heavy, you should only do this for a few minutes. Using the same method as before, open the caps and pour the cleaning fluid into your bucket. Your battery is ready for reconditioning.
Step 5: Recondition the battery
It’s time to recharge the batteries. You may make your electrolyte with purified water. This raises the voltage and amps the current supplied to your car. It also prevents the battery from being killed by plate sulfation. To make your mixture, combine the Epsom salt with distilled water that has been brought to a boil.
The electrolyte is ready to fill the cells after the water is clear. Fill each cell with your mixture using a clean funnel. Ensure that it is up to the brim until it is completely full. If there is any left over, it can be saved for another time. Replace the caps on the battery and shake it for a few minutes more. You have everything you need to charge the battery.
Step 6: Charge the reconditioned battery
Remove the caps to prevent the electrolyte solution from overflowing and heating up. It can cause a lot of problems if the battery builds up too much pressure. Your battery charger should not be anywhere near your battery. Connect the positive lead to the positive terminal of your battery. Carry out the same procedure on the negative side. Charge your battery slowly for an hour and a half.
Step 7: Test your reconditioned battery
Once the voltage has returned to normal, remove the battery charger. Replace the caps and reconnect the battery to the vehicle. Turn on your high beams, but don’t start your car just yet. Allow the battery to run for a few minutes under load. Then, take another reading with the voltmeter. You should observe at least 9.6 volts. If it’s less than 9.6V, the battery hasn’t been fully reconditioned, and you should try again.
The battery can also be recycled. If it fails after the first load test, thoroughly discharge it and recharge it. Simply put the battery under load by leaving the high beams on to drain it. It may take four to five cycles of cycling the battery to acquire the correct reading. However, once you’ve done so, you’ll have a completely functional battery for a fraction of the price of a brand new one.
Several hazards to consider when working with car batteries
There are several hazards that you should always consider every time you are working with car batteries. In this part, we will discuss some of these things.
This substance is toxic and will burn your eyes or skin if you come into contact with it. It can even eat holes in your clothes, which is why you should always use caution while working with auto batteries.
Car batteries emit hydrogen gas. This gas is highly flammable and easily ignites. It could produce a fire or explosion if it builds up in a compact place, such as a garage.
Car batteries can ignite, especially when jumper cables are attached.
