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.

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. In short, 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.
