How to Recondition Laptop, Ni-Cad, Hybrid, Car and Lead Acid batteries

How to Recondition Batteries? Is it Possible?

It is not necessary to dispose of all batteries that you use. Learning how to recondition old batteries could be an ideal solution to people who dispose of batteries when they seize to function. The cycle of buying batteries over and over is uneconomical and a waste of resources. There is a misconception among people in regards to reconditioning and recharging for being similar. Recharging a battery in fact only gives power for a period of time while ez battery reconditioning restores the battery to its full capacity. In learning how to recondition a battery, you will come across various methods approached in reconditioning of different batteries.

Hybrid Battery Reconditioning

For many owners of conventional vehicles, buying a battery is no big deal. With some retailing as low as $30 with most expensive brands going for a range of $80 to $120, they could worry less.On the other hand, replacing a hybrid car battery could cost the owner a whopping $3000. Hybrid cars rely on their battery packs to provide some of the power needed to propel the vehicle. Hybrid car batteries have a long lifespan of around 10 years or 100000 miles.Hybrid car batteries can however be reconditioned. A hybrid battery is warranted for the lifetime of the vehicle. If a battery life extends beyond its warranted period then the owner needs to replace the battery at their own cost. The owner can result to getting that battery reconditioned. Reconditioning extends the lifetime of a hybrid battery by six years.

How to Recondition a Car Battery?

Car batteries are an important component in the functions of a vehicle. Many people discard them after they are used without the knowledge that car batteries can be reconditioned. There are several things you will however need for this task such as a voltmeter, battery charger, distilled water and a syringe. The steps that you will follow are:I. Remove all the six caps that cover the cells from the battery together with the rubber that protects the caps. You may need a screwdriver if they are tightly held.II. Then, fill the cap with distilled water and charge it for an hour. You expect to see bubbles. If bubbles do not appear, exchange the negative and positive terminals. If the bubbles appear, take back the wires to their correct terminals.III. As an addition, you can replace the acid inside the battery with new acid. Anyway, you will still have a new battery.

How to Recondition a Laptop Battery?

You should make sure to check the type of battery your laptop has before you start this procedure. If the specifications in computer advice that it is a Li-ion battery, you are free to proceed. I will use the Li-ion as an example considering that most laptop batteries nowadays are made using lithium shifting from Ni-Cad and Ni-MH batteries that were used before. There is however no clear way to recondition a laptop battery. For this procedure I would suggest that you use an old and dead battery since there is not much damage that you could cause. The following are the procedures that could guide in this project:I. Using a flat screwdriver, remove the casing carefully to prevent the inner casing inside from being damaged since it is useful in the revival of the battery. This will require a lot of patience.II. For this procedure to be effective, a new battery is important. You can buy new batteries at a very low price from a trusted dealer. For long life service, you can buy genuine high capacity battery.III. A Li-ion laptop battery contains a series of cells pared together. You need to understand how these batteries are connected to the main power wire of each end, to the controller and to the sensor wire.IV. Replace the old batteries with new ones by detaching the wires that may be welded and soldering wires connected to the new batteries.V. As I stated earlier, Li-ion has a series of cells. In this step, you need to replace the old series with a new one.VI. After you build your new series, you can connect it to a battery case.VII. At this point you can connect the battery to your laptop to see if it works.

How to Recondition Ni-Cad Batteries?

Nickel cadmium batteries can be reconditioned as well. They however contain sulfur crystals that build up inside the battery. These crystals need to be destroyed or vaporized at high voltage. It is not as difficult as it sounds. The equipment you need for these tasks are; a battery holder, a dead and fully charged Ni-Cad battery, a capacitor (which you can retrieve from a disposable flash camera), a high power switch, a small switch and wires. You may also require tools such as; a flat head screwdriver, soldering iron, wire clippers, pliers, wire slippers and tape. The procedure for reconditioning of NICAD batteries is as follows:

I. Using the flat head screwdriver, open the case of the disposable flash camera and discharge the capacitor. You should be alert for a spark in this procedure.

II. Replace the metal parts in the circuit with a small external switch for ease of control. Solder two pieces of wire to the circuit and make sure to tape it to prevent being shocked.

III. At this point of the procedure, you should add a high power switch and a battery holder. Solder both the black wire and red wire to the negative and positive terminals of the battery respectively. Then solder the high power switch with respective wires from the battery.IV. In this procedure, you should case the high voltage areas to cover the exposed areas of the circuit for safety. If you do not have a box to case the capacitor, you can use the tape.V. Place the dead battery to the battery holder and connect them to a good battery using a good alkaline battery and turn on the light switch. When the led light starts to glow it means that your battery is coming back to life.

How to Recondition Lead Acid Batteries?

A well reconditioned battery will yield performance of around 60-70% its potential capacity. You need safety glasses, screwdriver, plastic funnel, battery post cleaner, battery hydrometer, battery load tester, voltmeter, sulfuric and lead acids. The procedure for lead Acid Battery Reconditioning is as follows:

I. Use the post cleaner to clean both the positive and negative posts of the battery to get rid of corrosion and dirt.II. Check your battery’s volts for weak cells. You need to replace the cell if they are weak of dead.III. Using a flat screwdriver, remove the caps of the battery.IV. Use the voltmeter to test each cell for 2 volts. Any cell with volts below 2 is dead and needs replacing.V. For the cells with more than 2 volts, use a battery load tester to ensure there is a collective reading of 12 volts.VI. Using a battery hydrometer, you need to check on how much charge you need to get your battery fully charged.VII. Add Epsom salt using a plastic funnel to the six cells of the battery.VIII. Charge the battery for 24 hours. In this step, you will have your conditioned battery in full swing.

Battery Reconditioning using Epsom Salt Method

This is the method actually used for Battery Reconditioning Epsom salt.

Dead Batteries found in your CAR, motorcycle, tractor, boat, golf cart or EV are called LEAD ACID BATTERIES.

LEAD ACID BATTERIES are the most economical and simple structured in nature.

And Fortunately, you can Recondition that at home with very few inexpensive ingredients.

The main con of the Lead Acid battery is heavy and get dead when left discharged for short period of time.The lead-acid battery does best when they get fully charged.epsom salt battery reconditioning

To get your battery new life get EPSOM SALT(magnesium sulfate).where the hell you will get this stuff? The answer is at Department store.It is so cheap. like 4lbs of Epsom salt for $2.40 at Wal-mart. and 2 gallons of distilled water for $1.46.

Don’t use tap water or well water.

So, let’s start:

Following things you will need:

Your Battery which you want to recondition
Epsom salts(magnesium sulphate)- 200g(7oz) [Price:$8-9 ]
400ml(12oz)-Distilled Water [Price: $5-$6]
A battery Charger [Price: $18-$20]
A syringe or Dropper [Price:$3-$4 ]

Steps for Battery Reconditioning using EPSOM Salt

Take the battery out of your Vehicle.Put it on some solid workbench or something where you’ll get firm support.epsom-salt-battery-out-of-vehicle
Now, Each battery will have something different when it comes to packing them.Like some batteries will have sealed caps with screws.Otherwise, batteries having “sealing stripe”.taking-out-sealed-caps-of-lead-acid-battery image credit:larkinweb


You may need to cut that sealing stripe.It is easy. Almost removable.

Once it is removed, you need to take the caps off the battery from individual that you will get battery acid.

Now, use the syringe or dropper(carefully) to drain[cause water to run out] each cell one by one and step-by-step until they are all around 50-60% full.
dropper epsom salt


If some cell probably will have lower than those of other cells.

So, exchange some acid from fuller cells.

Don’t take too much acid out, then you’ll struggle to recharge.

This is a strong acid, so put in the glass container.Don’t mess with this.Be careful.

Here’s come part of some Epsom salt.
You have to make a mixture of Epsom salt and distilled water.epsom salt and distilled water

You have to make it saturated.

Do this by boiling water and stir continuously in more salts until no more will dissolve in the water.

It’s time to fill each cell with an Epsom salt solution to the full-level-line using syringe or dropper.

Now, Charge Battery 😊
While battery being reconditioning, some gases will be, you should leave the cap open for some time.epsom battery charger

Connect the terminal to the battery charger.

And let it complete charging cycle.

Sometimes battery gets heavily drained or damaged.In this case, it may have to charge overnight using trickle charger at a very low amperage.

If you don’t have a battery charger. don’t worry we have another option.

Replace the battery cell caps and covers.

Reinstall battery into the vehicle.(car, golf car etc.)

Now jump start it.

Take a car for half of the full hour drive to allow the battery to charge using an alternator.

Now, this reconditioned battery at least last for 6 months or a year.

7.This can be done for more than 4-5 times until it is no longer effective.

here’s ultimate guide for battery reconditioning.

Theory Behind Battery reconditioning using Epsom salt:

You know why lead-acid batteries die more often?

It is due to there is an accumulation of Lead Sulphate Crystals on the plates inside the battery.[battery consists of a lot of plates inside.]

Actually, a battery is a small chemical plant which stores and restores energy into its plate.

They get charged with an electrolyte. The electrolyte is a mixture of distilled water and sulphuric acid.

When a battery gets discharged, what actually happens is a lead active material which is from positive plates reacts with the sulphuric acid and produces lead sulfate.

Now, this process is reversed to sulphuric acid again.

The battery fails when excess lead sulfate is built upon crystals which do not allow sulphuric acid to make contact with sections of the plate.

These crystals harden and eventually cause a chemical imbalance in the electrolyte.

Hope you’re getting this simple theory concept.

Have a great day 😊

However, there is no need to stress, because a simple set of principles will let you know whether a battery is safe to recondition or not.

Do not try reconditioning a battery without security gear

Apart from which, over eighty percent of batteries are perfectly secure to recondition. Of the remaining twenty percent, another ten percent will not give any trouble to you. What this guide will tell you about is how to recognize the eighty or ninety percent of batteries which are secure to recondition, and also, just as importantly, how to recognize the ten percent or a lot of batteries which should not be emptied under virtually any circumstance.

There are complex layers within a battery which sustain the chemical reactions, and when these layers have been breached it can cause short-circuits or an intense chemical reaction resulting in a fire. If you can observe such visible damageis get rid of this battery.

In the very minimum, you want a fantastic excellent charger, optimized to the specific sort of battery that you’re working to recondition, as well as rubber gloves that reach beyond the elbow, if possible, as well as a rubber mask for the face with big glass goggles that will not be exposed to the corrosive acids at a lead-acid battery, such as. That has been.

This is very simple to inform, in-so-much-as a battery can be reconditioned so long as it doesn’t demonstrate any of those danger signs that indicate it should not be so. To put it differently, as a general rule, all batteries can be reconditioned by you till they show some signs of being dangerous. I will be telling precisely what these danger signals are.

Let’s begin with when you should go right ahead and recondition battery.

However, besides these, at the other times, reconditioning a battery is not just safe, but it’s advised and will surely save you money. If you do not own the gear that is ideal, and the right safety gear isn’t owned by you, then I would counsel you to not try and recondition the battery.

The first skill which you will need to develop when you get in the business of reconditioning batteries would be the capacity to analyze a battery and also to figure out if you should try to recondition it leave it alone.

The next point at which you should abandon reconditioning a battery is, if you’ve actually implemented the reconditioning process one or two times and it has not worked.

This is an important skill, because batteries can be extremely unstable, and if you attempt to recondition a battery that’s been severely damaged, then you may place the battery on flame, or even cause an explosion. This depends upon the kind – .

It means that something has really gone integrally wrong with the battery, and further attempts to recondition the battery could only end up being harmful. You have to properly recycle the battery.
