Should Lithium Batteries Be Fully Discharged – Quick and Correct Discharge Method

A discharge or charge cycle refers to the complete discharge of a battery after charging. However, the battery is never fully discharged. Manufacturers use an 80% depth-of-discharge formula to rate batteries. For this reason, 80% of the available energy is delivered while 20% is retained. In addition, the manufacturer claims that the life of the battery increases when the number of cycles of the battery falls below a full discharge. Lithium technology can also cause extreme heat generation and internal short circuits.

Can a lithium battery be fully discharged?

Lithium batteries are not suitable for deep discharge, as everyone knows. Generally, the fully charged voltage of a lithium battery is about 3.65V, and 20V is the fully discharged voltage. This means that overcharging will bring more energy to the battery, thereby destroying the battery. Damage can be extreme and caused by shooting.

Most devices today use lithium batteries that have no memory effect. Always try to partially discharge to around 40% to 70% before charging the battery. Conversely, you should not leave the battery fully charged for extended periods of time. This will reduce lifetime and capacity loss. If you want to keep it for six months, please charge 50% before storage. However, if you use it a lot, you don’t need to be nervous.

Shallow discharges only cause minor problems. For example, a PC might get confused and display the wrong battery percentage. Laptop manufacturers recommend that users perform a full discharge once a month. It will assist in measuring the battery of the device based on the estimated time. Do not leave the battery in a deeply discharged state for an extended period of time. Batteries cannot discharge to zero, but if they do, charge them as soon as possible. Avoid leaving an uncharged device without charging.

What is the fastest way to discharge a lithium battery?

Most modern lithium batteries have internal circuitry. This prevents them from discharging deeply, which can lead to battery damage. You can discharge them to C/10 until no current flows. Let’s say they are 5Ahr and can discharge to 500Ma. Most battery packs have the same C/10 rate.

A resistor or LED can discharge the battery safely and quickly. You need to make sure the resistors are rated above the 100mA spread. If you need a 2W resistor, add a fuse to produce 200mA. By ensuring process safety, resistors are the right choice. The cool stuff keeps the insulation from melting and damaging the battery. It provides enough resistance to keep the temperature cool.

How much can a lithium battery discharge?

It is recommended to store lithium batteries to 40% discharge. It’s safe if you’re going to keep it long term. If it is held at full charge, oxidation will be at a high rate. Additionally, lithium batteries have a safety built-in circuit that turns on when their discharge voltage falls below 2.5 volts. Do not discharge the battery beyond the manufacturer’s instructions. Finally, a deeply discharged battery should not be charged immediately, especially if left in that state for an extended period of time.

Lithium batteries have no charge memory effect. Use partial discharge instead of deep discharge. Lithium battery experts suggest that it can be fully discharged after 30 charges. Continued partial discharges can cause digital memory and degrade the accurate performance of the device.

Lithium battery discharge guide

1. Never discharge a lithium battery at a higher amperage rate than the specific label on the battery

2. The battery temperature should not exceed 140 degrees Celsius. Cool the battery while discharging.

3. The battery should not be discharged below the marked voltage. Discharging below recommended voltage can damage, degrade performance and cause fire.

4. The discharge voltage of lithium batteries in each battery should not be lower than 3V. Follow the cut-off voltage.

5. Keep an eye on the battery and monitor for potential problems that may arise

6. If something goes wrong, stop the process immediately. Put it in a safe place and assess the problem.

7. Check the condition of the battery. If the battery is not properly balanced or swollen, stop using it. The safety of your equipment is in your hands to avoid accidents.

What are the laptop battery types? Is it a lithium battery?

Of all these devices we use in our daily life, laptops are one of the most important. These mobile computers have now become the offices of some occupations, they can’t do anything without a laptop, and every file and document they used to be physical has now become a digital file kept in the laptop.

Talking about these laptops now, the thing that runs them for hours so that we can sit and work anywhere we want without any trouble without having to plug a power cord into a power outlet is the battery inside these laptops. These rechargeable batteries make our lives much easier and less busy. How are these batteries able to charge these devices for so long? What are they made of? These are some curious questions, and we’ll reduce their curiosity by answering them here. Let’s have a look!

What is the battery type of the laptop?

The most popular batteries today are lithium-ion batteries. The two older types used are nickel cadmium (NiCad) and nickel metal hydride (NiMH). Both batteries suffer from the dreaded memory effect, which is why they fail in laptops. The dreaded memory effect, also known as the battery effect, causes the battery to hold less charge and the battery seems to remember less of the capacity. However, lithium-ion batteries are known to have no such memory effect at all. However, if they are repeatedly charged after only being partially discharged, they may lose some capacity.

These Li-Ion batteries can be recharged 300-500 times and have the ability to disconnect the charging process when fully charged through their internal circuitry. All of these are paramount for laptop batteries, and lithium is by far the only metal that falls into this category.

Lithium metal was first used in these batteries, but it inherited stability issues, especially during charging. Because of this safety concern rather than lithium metal, lithium ions are now used to make these batteries, which have slightly less energy than lithium ions, but are safer. Lithium-ion is also a low-maintenance battery with a low self-discharge rate compared to their predecessors (i.e. nickel-cadmium and nickel-metal hydride). These qualities make them ideal for modern fuel gauge applications such as laptops and mobile phones.

How to maintain the laptop lithium battery?

Following a few guidelines for proper care of a lithium-ion battery may improve its lifespan and help keep it healthy. The first thing to note is to keep the battery at room temperature. Make sure your laptop isn’t too hot or too cold, which could damage your battery.

If your battery isn’t on the laptop and you want to store it separately, store it in a place that’s always warm, like the refrigerator. Yes, the refrigerator is a great place to store the battery separately from the laptop, on the bottom of the refrigerator, not the top. Wrap the battery so it doesn’t get wet inside. Or place it on a shelf out of direct sunlight where it will touch the battery.

Avoid fully discharging the battery, recharging after partial discharge, time and time again, it will damage your battery, don’t charge it unless the battery is below 30%. By following these simple steps, you can keep your battery safe.

Anyone who uses a laptop must master these basics in order to keep their laptop battery in good condition and healthy. These guidelines will help keep your batteries healthy, store them in a way that won’t hurt them, and keep them in standard condition for a long time.

How to calibrate a MacBook battery

You’re using a MacBook and wondering if it’s possible to calibrate the battery? Most laptop batteries require calibration to help check the battery and understand its condition. You might be using a dying battery, but you didn’t notice it because of the wrong information provided. Your system’s battery reading is often critical to giving you battery usage directions. It is generally recommended that you calibrate the battery twice a month for proper readings.

This article will tell you if and how to calibrate your MacBook battery. Let’s take a look below!

Do you need to calibrate your MacBook Pro battery? The power management system of a notebook battery plays a vital role in the entire battery life. Therefore, after installing a new battery twice a month, the power management system must be calibrated.

Batteries should be calibrated after battery replacement, as it allows the battery to reach its maximum charge capacity, allows the new battery to reach its full useful life, and allows the system to accurately display the battery level. All MacBooks, MacBook Pros, and MacBook Airs use batteries with built-in processors to maximize battery performance. The battery and its processor must go through a calibration procedure to accurately predict the remaining battery charge.

Properly calibrating and maintaining your MacBook battery can improve its performance and delay battery replacement as long as possible. Therefore, obtaining accurate information is more important than maintaining the battery.

How do I calibrate my MacBook Pro battery? The battery calibration process has several well-organized steps. Therefore, use the following steps to calibrate your power management system:

1. Plug in your MacBook.

Plug in your MacBook charger and make sure it’s charging. Chargers and computers usually have an indicator light to indicate that the battery is charging.

2. Fully charge the battery.

You must make sure the battery is fully charged and the computer shows 100%. When fully charged, the light on the power adapter will change from orange (charging) to green (fully charged). To do this, you can flip the laptop over and press a button on the battery. If the battery is fully charged, all lights will turn green.

3. Make sure the battery is fully charged for two hours.

You should keep the adapter plugged in the entire time and make sure the adapter light stays green. Works fine on the computer, but don’t shut down the computer at any given time.

4. Disconnect the power adapter.

After two hours have passed, you can disconnect the adapter from your MacBook. This process will give the power management system time to analyze the battery.

5. Fully discharge the battery.

Keep your computer powered on and in normal use, and once the low battery life warning appears, save your work. When the battery is low, it will automatically go to sleep.

6. Leave the computer for 5 hours.

Do not charge the battery immediately. Give it at least 5 hours to release the last remnants of the battery. It also resets the processor to detect absolute zero power.

7. Charge your MacBook.

Charge the battery after 5 hours as it has been recalibrated. Your MacBook will start showing accurate battery status at all times.

This process takes a lot of time, but it’s good for your battery.

How many times can a Mac battery be cycled? Current Macs (i.e. MacBooks, MacBook Airs, and MacBook Pros) use batteries that have been rated for 1000 battery cycles. That means this battery is good enough for at least three years of normal use.

Older types of Macs have batteries with 300 battery cycles, which means they have a shorter lifespan. Manufacturers use battery cycles to estimate battery life. Knowing your battery’s life cycle and remaining cycles will help you decide when to replace the battery.

To get more information about your MacBook Pro battery and battery cycles, follow these steps:

Press and hold the Option key, then click the Apple menu. Select the System Information option. Under the Hardware section of the System Information window, select Power. You will see the current cycle count listed under the Battery Information section.

What do I do with my old lithium batteries – here’s what to do

The superior performance of lithium-ion batteries, to a large extent, explains the superior performance of most electronic devices. However, special attention should be paid to lithium batteries as they age over time. If these batteries are handled in the wrong way, fire, contamination, and other negative effects may result. To prevent this negative effect from happening, you should do something to properly dispose of the battery.

They are listed below:

1. Make sure the battery is removed from the unit and away from the main unit before further material recycling.

2. If the battery cannot be easily separated from the device, consult an expert to remove the battery. Experts should be properly licensed in their facility.

3. After removing, the battery terminals should be insulated to avoid short circuit.

4. Batteries should be stored in UN-approved buckets or boxes, separated by dry sand and vermiculite.

5. Batteries with damaged packaging, leakage or swelling shall be processed according to the above-mentioned UN-approved barrel packing process

There are also things you shouldn’t do when dealing with lithium batteries.

Lithium-ion batteries cannot be subjected to the following treatments, which include:

1. Lithium batteries are disposed of with regular garbage.

2. Squeeze, puncture, throw or do anything that could cause the electrodes to contact and short circuit

3. Mix damaged and undamaged batteries

4. Putting a large number of batteries together without proper isolation as this may cause a fire hazard

5. Place batteries or products containing batteries in any process not specifically designed to contain batteries

6. Store discarded lithium-ion batteries at home, as these batteries are prone to short circuits and catch fire.

Lithium batteries contain a variety of chemicals. If it is not handled properly, it will cause serious consequences, such as environmental pollution and resource loss. Lithium has high activity and is difficult to control. Effects such as high temperature, high charging voltage, short circuits, and even excessive pressure can cause exothermic reactions that release energy through light or heat in the battery.

Lithium batteries contain a polypropylene film that separates the electrodes and prevents short circuits. Therefore, if the device is crushed or punctured, a thermal event can result, as the battery shorts out when the thin-plate separator between the positive and negative components of the battery is destroyed. The larger the battery, the stronger the thermal response. In this way, incorrectly discarded batteries may ignite other nearby flammable materials. Especially when collecting a lot of batteries, it is possible that only one Li-Ion battery will ignite.

Why Lithium-Ion Batteries Swell, The Dangers Of Swelling, And How To Fix It

Lithium-ion batteries are the most commonly used batteries worldwide. They are mainly used in mid-range appliances such as laptops, cell phones and cordless phones. Due to their high functionality, they are used a lot. Despite their high capacity, they swell easily. This caused disdain from a lot of customers, who wondered why this was happening and if they had a way to fix it. The following will tell you, and will also tell you how to solve this problem, let’s take a look!

What causes lithium-ion batteries to swell? The reasons are as follows:

The general cause can be understood as what happens at the surface level that causes this expansion. Details are as follows:

1. The battery charging time is too long, and the stored power in the battery is too much.

2. The excess electricity causes various reactions (technical reasons), resulting in swelling.

3. In short, swelling is caused by overcharging the battery.

Technical reasons

The technical reason for the swelling can be understood as the science that happens inside the battery that causes this swelling. Simply put, they are the result of overcharging. The technical reasons are discussed below:

1. An undesired reaction between the electrodes and the electrolyte can cause an imbalance within the battery, which can lead to swelling. As we discussed in General Reasons, this imbalance is caused by too much current being directed to the battery.

2. Unwanted reactions can lead to the release of gases which, when expelled from the battery, can eventually cause the battery to swell.

3. These reactions can lead to contamination of waste particles within the battery. These particles take up more space, causing the battery to swell.

Are Swollen Batteries Dangerous?

To judge whether a swollen battery is dangerous, we have to look at swelling in two ways. Then we can take the appropriate scale to judge whether it is dangerous or not. This will help us determine our immediate response if we happen to encounter a swollen battery.

Dangerous ways of swollen batteries are as follows:

1. Since there is more power in the battery than needed, when this current reaches the components of your device, it has the potential to damage those components. It can cause burning or failure of these components.

2. There is usually a designated space for the battery in a typical device, and if the battery swells, it will start destroying the device from the inside to make up the space needed.

3. In older versions of Li-ion batteries, an overcharged (i.e. swollen) battery could explode and splash around.

Here’s how to swollen batteries in a non-dangerous way:

1. In general, some lithium-ion batteries fail if they are overcharged. This means they will have significantly less functionality and will not cause other problems.

2. Lithium-ion batteries in new devices no longer explode. This is the result of the new technology strategy employed by these batteries.

How to prevent swelling?

You just need to make sure you don’t overcharge your battery. In other words, keep an eye on your rechargeable battery and remove it when it reaches 100% charge.

What to do when your lithium battery swells? If your lithium battery swells, you can do the following:

stop the charging process

As soon as you notice (or worry about) your lithium battery swelling, you should stop charging it. Once the battery starts to swell or gets close to that point, the situation deteriorates rapidly, so action needs to be taken quickly to avoid any undue harm to the person, the battery, or the equipment that uses the battery.

Safely remove the battery

You should use the appropriate method to remove the battery. This means that you should first turn off the device, unscrew the case properly, and then remove the battery, preferably with all safety measures intact. This will allow safe removal without damaging your device or components of that device.

Properly dispose of batteries

If the battery does swell, there’s nothing you can do about it. Remember, you can’t just throw it in the trash. There are proper procedures for battery removal and you must follow local guidelines to do so. You will most likely have to hand over the battery to an authorized organization.

Replace with new battery

Since you’ve disposed of the previous battery, all you need to do now is buy a new battery. Just make sure you get the same replacement battery that you used before, as this will work best for your device.

Is an overcharged battery fixable and how

Since we all use appliances and items that run on or use batteries, most of us have probably encountered an overcharged battery. In general, these batteries can be cumbersome and sometimes may not even realize their batteries are overcharged. This dilemma has led to a lot of questions about the safety and use of overcharged batteries.

Can an overcharged battery explode?

It depends on the type of battery

There are many types of batteries, and not all of them will explode. Some batteries, such as lead and sulfuric acid, can explode because they start to spark when overcharged; if both oxygen and hydrogen are present during the spark, it can cause a catastrophic reaction, possibly emitting shrapnel and acid mist nearby.

While it is well known that the type of battery is the main determining factor, we should keep in mind that the environment also plays a role. E.g:

Heat makes the battery more likely to explode.

Depending on the user’s usage, the battery may or may not explode.

Smartphone Batteries No Longer Exploding

It’s important to remember that smartphone batteries are unlikely to explode these days unless your model is fairly old. That’s because today’s batteries are “smart batteries,” meaning they’re designed in a way that greatly reduces the power input they receive, and when the phone’s battery reaches 100 percent, they have a minimal charge capacity. This was done because previous lithium-ion batteries would overcharge and explode, damaging not only the phone but the owner as well. This battery system has since been developed.

Do overcharged batteries work?

You need to know if an overcharged battery works. Unfortunately, the answer to this question is rather ambiguous and needs to be explored a bit:

Inconsistencies can occur with overcharged batteries

It might work if your battery is overcharged, but there will be inconsistencies. By inconsistency I mean:

From time to time you will hear sparks from the battery which may also affect the performance of the objects you are using. If you’re using a device with a screen, you might notice it fluctuates a bit. From time to time, your device may also shut down because it can’t handle too much charging.

You need to understand that an overcharged battery doesn’t mean better performance. Wiring has capacity, and if it receives more than it can handle, it will only damage, not improve.

There is a threat of burning equipment components

If you’re using an overcharged battery, your device may work but end up causing damage to your object’s components, especially due to burns. This means that using an overcharged battery is not sustainable.

In some cases availability may not exist

Some devices may not be designed in such a way to accept overcharged batteries. Also, some batteries may have a malfunction feature that stops use when overcharged. All of this is ultimately to protect wiring and components.

How to fix an overcharged battery?

Consider discharging and charging again

One of the main solutions to “fix” overcharged batteries is to discharge them first and charge them again, but this time to a normal amount. This is a good strategy because overcharging can be devastating, and if you discharge it and bring it back to normal, it will make your battery fully usable again without technical issues.

There are many ways to discharge a battery, so some precautions must be taken:

Most batteries can be discharged in various ways, not all of which are safe or ideal for them.

Damage may be irreversible

While a discharged battery can be reused, it should be noted that during overcharging, there is also some potential damage to the battery itself, making the battery unfit for use. In this case, you may not be able to reuse the battery unless you replace its components. However, just buying a new battery is better than simply replacing components.

How to wake up a dormant Li-Ion battery – method

Lithium-ion batteries are rechargeable batteries that are ideal for most electronic devices such as smartphones and laptops. The battery contains a protection circuit module. The protection circuit samples the voltage in the lithium-ion battery and outputs the same sampled voltage. This protection protects the battery from abuse and can be turned on and off. It is also activated when the battery is over-discharged, rendering it unusable. This happens because the protection circuit is designed to detect the battery voltage and cut off the lithium battery if the voltage falls below a specified voltage. When this happens, the battery goes into sleep mode. Let’s look at ways to wake up a Li-Ion battery that is dormant, whether it can be overcharged, and its life cycle. Let’s have a look!

How do I wake up a Li-Ion battery from sleep mode?

When the Li-Ion battery is insufficiently charged, it enters sleep mode. This can be a cause for concern, as most people consider such batteries useless and throw them away, as chargers often render them unusable. However, sleep mode should not be a cause for concern, as some analyzers and chargers have boost and wake-up functions to reactivate such batteries. The boost activates the protection circuit by applying a small charging voltage. When the correct battery voltage is applied, the charger can charge normally.

Let’s look at ways to wake up a sleeping battery.

Step 1: Read the voltage.

First, you need to confirm whether your lithium-ion battery has any remaining power. First power off the electronics and remove the battery. Using a voltmeter, read the voltage to check if the battery has any juice. When doing this, keep in mind that different manufacturers cause the battery to go into sleep mode at different voltage levels. So it’s best to be familiar with your battery capacity to be able to wake it up.

Step 2: Connect the charger.

Using a suitable charger, connect the battery for a few minutes while watching for any signs of damage and healing. Use a charger with a “boost” or “wake up” function. Keep in mind that boosting Li-Ion batteries with voltages of 1.5 and below is not recommended. This is because a battery that is undercharged for a long time can develop a copper shunt that can cause an electrical short. These shorts often cause the battery to overheat and possibly explode.

Step 3: Read the voltage again.

Check the voltage with a voltmeter. A higher reading than before means the boost is working, the same voltage means the process was unsuccessful and you should consider buying a new battery. Make sure you check your charger manual to see when the process is complete.

Step 4: Charge and discharge the battery.

If the boost works, you can now connect the Li-Ion battery to the charger and fully charge it.

Step 5: Freeze the battery.

In an airtight bag free of moisture, freeze the battery fully charged for a full day, then allow the battery to cool until it returns to its original room temperature.

Step 6: Charge the battery.

Connect the battery to the charging system and fully charge it.

Can Li-ion batteries be overcharged?

It may damage the battery and even cause harm to the user’s health. Lithium-ion batteries can accept partial charges, so overcharging is impossible. Protection circuits in these batteries prevent the flow of ions by suppressing overvoltage when temperatures get too high.

The battery management system in most lithium-ion battery packs also makes overcharging impossible. An internal circuit monitors the state of charge of the battery and cuts off the current when the limit is reached. If your Li-ion battery is overcharged, the charging system is mostly defective.

How long can an unused Li-Ion battery last?

Batteries in the product or in storage should not be left idle for long periods of time. If the battery has been unused for six months, check the battery status and charge it appropriately or discard it. Lithium-ion batteries have an estimated lifespan of mostly 2 to 3 years or 300 to 500 charge cycles. That is, from it being fully charged to fully discharged and fully charged. Since rechargeable lithium-ion batteries have a limited life cycle, they will gradually lose their ability to hold a charge, and most of the time you will need to replace the battery. All in all, the life of an unused battery will depend on how it is stored and external factors.

How to charge and restore a dead Li-ion battery?

Lithium-ion batteries are very useful in today’s electronic world. We use them at home, at work, at school, on portable devices, and many other places. Sometimes the battery can be restored if it is not charging or operating as needed. Here’s what you need to know about why lithium-ion batteries suddenly become unresponsive and how to restore them. Let’s have a look!

1. Can you revive a dead lithium-ion battery?

Yes. Lithium batteries are susceptible to issues that can cause them to be unresponsive to charging or discharging. To understand how to restore a depleted lithium-ion battery, you must understand how it works and its unique features.

How Lithium-Ion Batteries Work

“Lithium ion battery” refers to many types of batteries that rely on lithium ions to work. Their common feature is that they rely on anodes made of lithium compounds.

During charging, positively charged lithium ions move across the electrolyte to the cathode (negative electrode), and negatively charged ions are released from the cathode and move the anode. The opposite happens when discharging, the lithium ions move towards the anode. The problem is that if the battery is discharged for too long, the electrodes will over strip the ions.

If after this state of discharge, you try to charge the battery, the electrodes will reconstitute. This process is very irregular and can easily cause short circuits, fires and explosions. To prevent this, Li-Ion batteries are equipped with a battery management system (BMS) that measures the health of the battery based on the battery voltage.

What Causes a Dead Battery, Hibernates, or Bricks

If the BMS detects that the battery voltage is below a predetermined level, it will not charge it for safety reasons. That’s why even if you plug it in, it won’t charge and also shows the faulty battery indicator LED.

In most cases, this is what causes the battery to sleep. This battery can be recovered in the following situations:

● Not lower than the nominal voltage. For a 3.2 or 4V battery pack, this is usually 1.5V.

● Less than one week below the nominal voltage.

●No signs of physical damage.

While you can restore this type of battery to its operating state, be aware that the process can be dangerous. However, if you still want to restore it yourself, there are some tricks you can use.

How to charge a completely dead battery?

There are two ways to rejuvenate a depleted lithium-ion battery. The first involves its original charger or other approved model, while the second consists of another battery of similar voltage and capacity.

Restoring a Depleted Li-Ion Battery Using a Boost Charger

If the battery comes with a separate AC charger or cradle, check with the manufacturer that it has a “boost” function.

This is the function of the charger to check the battery to see if it is higher than the nominal voltage. If not, it applies the appropriate voltage to bring it back to acceptable levels. Different manufacturers have incorporated various features into these chargers. They usually display lights to show if the battery is charging. For some, you may need to manually switch between “normal” and “accelerated” charging. If the charger has an auto boost mode, let the battery charge halfway, discharge, and then charge normally.

Use another battery to restore a depleted Li-Ion battery

You can also use a similar rechargeable battery to “start” a dead battery. Here’s what you should do:

● Look for similar batteries with matching voltages and nearly similar charge capacities.

● Make sure the other battery is fully charged. It should have higher voltage.

●Connect the two batteries with a cable. The two positive terminals should match, the same as the negative terminals.

●Let them sit for 5-10 minutes, then disconnect the cables.

● Check that the previously drained battery is now higher than the minimum voltage, and then charge it as usual.

What happens here is that when the cells are equalized charging, the higher voltage cell directly boosts the lower voltage cell. If the voltage is higher than the minimum value, it can be charged normally with the charger.

3. How to extend the service life of lithium-ion batteries?

Lithium batteries degrade over time, just like all other types of batteries. However, this process can be slowed down by taking some precautions.

● Avoid deep charge cycles. Deep charging will drain their life cycle faster, while replenishing them from 50% power helps improve it.

●Keep low temperature. Lithium batteries love the cold, if your device lacks thermal protection, make sure to cool it down regularly.

●It is fully charged from time to time. This means that you drain the battery completely and then use the recommended charger to fully charge it.

● Track the expiration date. Even if a lithium battery is not used, it will still degrade over time because lithium ion batteries have a limited lifespan.
