How To Recondition a Car Battery and Other Batteries: Ultimate Guide

People often think that a dead battery should be discarded and pay huge bucks to buy a brand new one. While this is one option to retrieve a fully functional battery, it is not the only way. One can also recondition the batteries, i.e. restoring back the battery back to its initial condition and save money.  With some effort, you can get a 100% functional battery, and the following post is your step-to-step guide to recondition batteries.

Reconditioning old batteries is quite easy and anyone can learn to do it. All you need is time and some devices to recover a fully functional battery. Not only it saves your money, but you also save your mother planet by not polluting it. Your old battery will look as new as newly bought one, and you can also make off some money by selling them!

So we basically compiled a comprehensive battery conditioning article that’ll lead you to reconditioning any type of battery. Starting with car batteries of course, since Total Car Diagnostics is a car company after all.

Bon Voyage!

How to recondition old batteries

With more people participating in an endeavor to protect earth and reduce pollution by using power batteries based on renewable energy resources, it is important to maintain and recondition batteries to maximize capacity and reduce energy loss. Batteries have a certain life span and as they cross the mark, there is a distinct loss in capacity to hold a charge. The impact of old batteries on environment is around 50%, and imagine how healthier the planet will stay if everyone has this useful trick up his sleeves! Not only you stay green if you learn how to recondition your batteries, saving money and time resource are added bonuses!

But before we shall continue, it is important to know the differences between reconditioning and recharging. Reconditioning a battery means restoring battery back to its full capacity (it is as good as new!) while recharging simply means putting in charge for a period.

How to recondition batteries depend a lot on what kind of battery it is. For example, it can be Lead acid, or simple Li-ion battery. Correct knowledge of chemicals and proper handling is necessary for safe reconditioning of batteries. Often it is the old car batteries with highest demand for reconditioning, however, you also have house batteries for nearly free from scrap factories which can work for reconditioning as well. If you want to reduce energy for long time, you should learn how to recondition a battery! In addition, you might do good volunteering or side job of reconditioning batteries.

Reasons why you should learn Reconditioning batteries

  1. With an increased demand and supply for batteries in professional and personal front, reconditioning battery is one skill that would never go waste. Why not learn it when it serves our purpose to earn extra bucks and make our planet habitable. In case you are worried about your safety, be at ease. If the technique is properly learnt, it is quite safe.
  2. You practically get your old/dead batteries for free! You see, safe disposal is top priority, and many seemingly dead batteries are getting prepared for a new life, and you can help them ease the passage.

  3. Batteries cost a fortune, and you are saving a hefty sum if you simply recondition it instead of buying another one.
  4. If you want to go green and save environment while working on renewable energy resources, this is a good opportunity. Not only you learn a skill that will be highly coveted in future, but you can also earn some extra cash for other pursuits.

How to recondition your Dead car batteries

What do you plan to do with your dead car batteries? Just dump the old one and buy a brand new, costing you thousands of bucks when you can simply recondition it in range of hundreds? By the end of this section, you shall n=know how to recondition an old battery and make it nearly shiny new!

Usually, the 12 V car battery are Lead acid based with Lead terminals and Sulphuric acid as the electrolyte for the battery construction. We know about two types of car batteries-Flooded cell  (Wet cell) and Sealed cell (Dry cell).

what are flooded and sealed cells?

Flooded cells have detachable caps for each cell where distilled water is filled up to the working level. Although it lasts for about 4-5 years, it is quite sensitive and requires constant maintenance (every four months or so) to check and maintain water levels in the cell. It is the older version among two.

Sealed cells, on the other hand are the newer version of the cells that can last for about two years without maintenance. After that, it is not serviceable.

If you have Magnesium sulfate (commonly known as Epsom salt) with you can easily recondition a car battery.

Following steps should be followed to recondition a car battery:

  1. First step is to check the battery voltage and ensure it to be less than 12 V. This shows that it is already dead.

    recondition-dead-car-batteries-1
  2. Heat about half a liter of distilled water to about 333K-348K (about 30 K below the boiling point of the water)

    recondition-dead-car-batteries-2
  3. Now, mix about a quarter of Epsom Salt in heated distilled water and stir it until the salt dissolves.

    recondition-dead-car-batteries-3
  4. For two different types of cells, this step involves different procedures.For flooded cells, you need to remove the battery cell cap.For dry cells, please drill through the sealed cap.For both the cells, pour out the old electrolyte.

    recondition-dead-car-batteries-4

  1. Insert the new electrolyte into the cell with the help of a funnel. (mainly Epsom salt + water)
  2. Next, for a flooded cell, replace the battery cap. For a sealed cell battery, plug the hole in this step.recondition-dead-car-batteries-6
  3. Keep in mind that you have to keep electrolyte properly distributed with no hint of air bubbles inside the cell.
  4. Finally, charge it slowly by keeping it on trickle charge overnight and then let it cool. By morning, you have a reformed cell in your hand that performs as good as new!

You can obtain the battery charger at any workshop where you can borrow or buy it. Although it costs as much as a new battery, it is good for long-term applications.

How to recondition a hybrid car battery

One of the best cars on the earth, hybrid cars has two main components to consider-an electric motor and the battery. The battery generally lasts up to 200,000 miles. Although it usually lasts longer than warranty period, the old battery eventually goes stale, and each new battery costs around 3000$.

Below are the steps outlined for reconditioning a car hybrid battery:

  1. One thing to remember: all batteries contain modules, and although the quantity may vary, the core principle stays intact. The factories simply replace modules and sell them as brand new! And that’s where you play your part. It takes around 700$ to fi x damaged module, and your battery’s life is extended for another 6-7 years. You should also note that a reconditioned battery has output 70% of the brand new battery output, which is more than enough.
  2. First remove the battery followed by rubber which protects the caps. Remove all the caps of the battery. Don’t keep any cap on.

    hybrid-car-battery-recondition-how-to-1
  3. Don’t put the caps back. Charge the battery for about an hour, and you will see the bubbles on the holes. However, if there are no bubbles, reverse the positive and negative wires. Wait for about 2-3 minutes. You can now see the bubbles. Revert the wires back to the original position and recharge the battery for additional half an hour.

    hybrid-car-battery-recondition-how-to-2
  4. If required, you can also replace the acid inside the battery while mixing new acid with distilled water. Later on, recharge the battery for a few hours, and you get a battery which lasts for a long time.

How to recondition motorcyle battery

The most common batteries used in cars, motorcycles, marine machines, equipment etc. are Lead acid batteries. Once discarded, Lead acid batteries are quite poisonous for the groundwater and soil as it makes surrounding water and soil acidic. Let us make a small digression towards Lead acid batteries.

Lead acid batteries

Lead acid batteries are one of the oldest rechargeable batteries since 1800s. How do they work? The principle is based on production of electricity by a chemical reaction. The Sulfuric acid in the electrolyte reacts with the Lead oxide (PbO) and Lead (Pb) to form lead sulfate (PbSO4) which is the main culprit behind wearing out of batteries over years. Lead sulfate crystallizes and the battery stops recharging. When the layers of sulfate are deposited, the battery might permanently stop. How do we bring dead batteries back? By desulfation! The reversal of sulfation allows us to extend battery life.

Desulfation is quite a tedious and time-consuming process, but worth every second given its effectiveness. Desulfation is not as complex as it is made out to be. Firstly, you should remove the Lead sulfate build up. Next, clean the deposits with the help of Magnesium Sulfate or Epsom Salt. With Epsom Salt, distilled water and a regular Lead acid battery charger, you are ready! But for safety purposes, please ensure to put on protective gloves and eyewear.

Steps to follow:

  1. Take some clean and dry Epsom Salt into a dry cup. For an averaged sized battery, measure about 10 tablespoons of Epsom Salt.

    recondition-motorcycle-battery-1
  2. The distilled water should be heated up to temperature around boiling point. Add distilled water to Epsom salt to forma thick liquid and stir it properly to dissolve Epsom Salt well.

    recondition-motorcycle-battery-2
  3. Pour the mixture of distilled water and Epsom salt into every battery cell battery as much as possible.

    recondition-motorcycle-battery-3
  4. Plug in your charger after having the battery covered and set the charger for High Amps (high current). It is advisable not to use smart charger for more readable meter. Meter only shows two possibilities-“zero” or “charged”. Depending on the extent of sulfation, the entire process might take some time. Next, switch it over to low current and keep it charging until it is full.

    recondition-motorcycle-battery-4
  5. Once the battery is fully charged, discharge it and charge it again. The current should be low this time. Charging on low current enables the Epsom Salt to break sown the lead sulfate deposits on the battery. When you charge it on the second try, it is finally ready to soar! You can repeat the desulfation process for maximum five times on any battery which can extend its lifespan by years.

That’s all for reconditioning a dead Lead acid battery commonly used in motorbikes and cars. Now put this Holy Grail in effect for higher purpose!

Reconditioning golf cart batteries

If you are a golf cart owner, this section is definitely for you. It will save you a lot of money if you know how to recondition a golf cart battery. The process is easy to master, and with regular checks on battery, we find when to recondition for prolonged life.

For example, if you check the pace at which cart is accelerating or decelerating, it will give you an idea if it’s time in case any of the functions become abnormal. In addition, you may notice any erratic behavior while charging which gives away its state. Note the time taken for complete recharge and frequency. Is it too much?

So, let’s take a look at the battery from an expert’s perspective easily learnt at home. First of all, inspect every component of the battery as a part of routine. Start with rods. Rods play an important role in functioning of golf cart batteries and play a major role in electron processes. The sulfur deposits on rods are harmful for its functioning and delay its charging rate. Sulfur deposits are responsible for under capacity working in most of the golf cart batteries.

Be careful when you treat the battery cells. The deposits have to dissolved from the battery rods, and it’s not easy. Distilled water can enhance the procedure. You should use a mixture of Epsom Salt and distilled water for above.

Next, do a function check. Are there any signs of corrosion? This negative reaction is unavoidable given the nature of chemicals present in batteries. However, one can always apply a protective layer to avoid battery leak (in case it eats away the case). If you scrub the terminals with Sodium Bicarbonated scrubbing tool, it can remove the corrosion away. Next, you should look for battery voltage. Low battery voltage is a red flag one should heed to condition your battery before it shuts down in middle of something important.

 

HOW TO RECONDITION OTHER TYPES OF BATTERIES:

Reconditioning your laptop battery

A new laptop battery costs something around 100$, and finding out a new battery turns out to be pricey venture. In the following section, you shall learn how to replace laptop battery in four easy ways. But before that, we shall make a small digression on different types of batteries laptops use for better understanding.

Laptops come with various batteries. The most common batteries are noted below:-

  1. Lithium Ion (Li-Ion battery);
  2. Nickel-Cadmium (Ni-Cd battery);
  3. Nickel-Metal Hydride (NiMH)

Li Ion Battery

What is a Li Ion battery? Li ion batteries are mostly used in cell phones, laptops, surgical devices etc. It uses Graphite rods as Cathode and Lithium Oxide as anode. What causes it to age? The battery works on the principle of movement of two electrodes. However, with time, elevated temperature and prolonged cycling, the performance reduces over time.

A normal Li ion battery delivers 100% of the promised capacity for first year. However, it reduces considerably in following years. The depth of discharge determines lifetime of a battery. Li-ion batteries face stress from exposure to high temperature and high current.

recondition-laptop-battery-1

Following are the steps you should follow to prolong a Li Ion battery:

  1. Not only cycling, but environmental conditions also determine the lifespan of a Li-ion battery. If you keep fully charged battery at higher temperatures for prolonged times, it reduces the runtime considerably.
  2. So firstly, one should lower charge voltages. This is mostly done in case of satellites and electric vehicles.
  3. You can keep your device at “Long-life” mode. Also, remove the plug if you are it using laptop.
  4. Remember to keep airflow unobstructed. A cool battery extends the laptop battery ife while safeguarding the hardware.
  5. Also avoid “ultra-fast” chargers.

 

Ni-Cd and Ni metal hydride batteries

The reconditioning works for Ni-Cd and Ni metal hydride (NiMH) batteries. There are four steps to recondition a battery:

  1. Recalibration: if the laptop battery is not lasting as long as it should, then it is perhaps time to recalibrate it. How do you know when you need it? If the laptop battery fails to charge up to 100 %, or if OS indicates 40 minutes of power remaining, but laptop is dead before you know 38 minutes, it’s time to recalibrate it. Following are step to step manual to recalibrate it.

    recondition-laptop-battery-2
    Step 1: First, the laptop battery is charged to its maximum percentage.Step 2: Next, unplug the laptop from power source and deactivate your screensaver/sleep mode/hibernation mode in order to make it discharge faster. You need to ensure that the battery is discharged fully and laptop is running solely on battery. Use your battery until the power is shut off.Step 3: As the power shut off, allow the laptop to remain so for about 4-5 hours.

    Step 4: Attach your laptop back to the power source and charge it to full. Now your laptop should give you the correct readings of the actual battery capacity. After the laptop is powered back, reset your power management settings as they were before. Please ensure that it is properly calibrated.

  1. Cooling the laptop: This is especially useful for Lithium ion batteries that you cannot recondition by changing the electrolyte or removing any residue. You can buy a cooling pad in case the laptop gets too hot. Especially during summer, cooling pad is quite necessary. Keep the laptop air conditioned to maintain the temperature.recondition-laptop-battery-3
  2. Unplug at full charge: let the laptop battery charge up to 100 percent and then immediately plug it off. This is not effective for new Li ion batteries. For new batteries, you can first charge them up to 40-45%, then again up to 80-85%.recondition-laptop-battery-4
  3. When the laptop is plugged in, remove the battery: if none of the other methods work, you can always try removing the battery (if the battery is removable) while the laptop is connected to the power source. The chemical reactions shall continue despite its presence or absence in device. This step recalibrates laptop’s battery while extending its lifespan as an added bonus. However, keep in mind this step should only be done when the the menace of power outages are not present at your home/office.recondition-laptop-battery-5
  4. Finally, advice for truly old batteries: if your battery is too old or you find broken parts inside your battery, a refurbished or new battery would be a better option.

 

There are other solutions in the market as well. Some of them are as follows:

  1. Solution I: Watch this video and learn how to recondition a laptop battery.
  1. Solution II: Another way is to plug in the battery and then charge it up to 100%, and the again discharge it to drop up to 5%. Repeat the process several times in a row, and then you get a reconditioned battery at the end of the day. Although it is time talking, it is worth a try.
    recondition-laptop-battery-7
  2. Solution III: Although this method is a bit weird, you can always try. Remove the battery from the device and keep it in a plastic bag. Next, put the plastic bag in a freezer and wait for about half a day. Remove the battery from the bag and clean it properly after twelve hours are over. Place it back in a laptop and fully recharge it.recondition-laptop-battery-8

 

 

 

Reconditioning Ni Cd batteries

Again, like Lead acid batteries, the sulfate crystals actually prevent from charging as they block the terminals. These are easily remedied.

Steps to follow to recondition Nickel Cadmium Batteries:

  1. For this, we need a flash camera capacitor. A number of cheap cameras have parts which can be disassembled and their parts used.

    recondition-ni-cd-batteries-1
  2. Add a switch and battery holder to the capacitor. Stick the wires to the capacitor, connect them with battery holder, and switch.
  3. Keep in mind to have wires insulated and try not to touch wires or any device carrying capacity.
  4. Not put the alkaline battery into the capacitor and Nickel Cadmium battery into the battery holder.
  5. Switch it on and wait for LED to light up. Do the above steps repeatedly. If you hear a sound, you know you are in clear and Sufate crystals are being destroyed in the process.
  6. Although this looks complicated, the steps are easy to follow once you have assembled all the gadgets or components, and you get a reconditioned Ni-Cd battery!

How to recondition device batteries at home

Whether we have brought devices over Craigslist or market, we all must have noticed at least once a glaring trend over years. The battery life of devices reduce over time, unable to store electrons as much as it used to after repeated cycles of recharge and discharge.

This is exactly the reason why your cell phone or laptop purchased five years back now runs for less than half time compared to its initial output. It also explains why an upgrade in electronics boosts battery life a lot more than initially perceived by initial promise.

Our promise is simple. We will teach you methods and tips to recondition your battery, which not only will save your time and money in the long run, but also the extra hassle coming along with it. So here are few tips to keep in mind to not only renew its flaming beauty, but also reverse back its aging and vitality.

  1. Recharge properly: If you are among the people who think to fully discharge your battery to near 10% before plugging it back, or immediately deplug it after it touches 100%, think again. Most of the phones contain inbuilt smart chargers, which cut off charging after it is full. However, research has shown that you should not let charge fall beneath 70% . In fact, the battery life gets extended if you recharge it at or above 70%. So if you want your device battery ticking longer, plug it in before it reaches 70% mark.recondition-device-batteries-1
  2. Delete useless programs and apps: We all know some programs and apps kill battery lot faster than others. For example, Photoshop and video games destroy batteries than programs like Notepad and Safari etc. Often there are some programs that run in background which are not even that useful but still kills the battery. Please delete or uninstall those programs. Or you can also check activity monitor to see which app or program is using maximum battery and discard it if unnecessary.recondition-device-batteries-2
  3. Recalibrate your device battery: Often batteries give a wrong impression about the battery life or app usage (odd actually, but the apps often work against each other or support, which messes up with battery readings or predictions). In order to retrieve true battery percentage, you can apply a simple trick. Discharge the battery completely up to zero and further keep it discharged for another 24 hours to fully drain it. Next, recharge it back to hundred percent and you het the correct readings!recondition-device-batteries-3
  4. Reset device settings: Another alternative to step/tip (3) is to reset or your desktop/laptop/mobile setting completely to factory settings. This will recalibrate the device. Not only it refreshes the device, it also comes with the added benefit of deleting any malware/virus/Trojan/worm/spyware which may be draining your device.recondition-device-batteries-4
  5. How to recondition battery at home: if all the above fails, of course you have an option to recondition your battery at home. It is a lot easier than what is feared. A lead acid battery is a bit tricky, but laptops and cell phones mostly use Li ion batteries. Reconditioning a Li ion battery is as easy as simple recalibration! Continuous recalibrations over years make the Li ion battery as good as new and vastly improve battery life and performance. If the laptop or mobile is virus infested, it is recommended to follow step (4) before (3).
