How do I know if my lithium-ion battery is bad?

The three common ways to tell if your lithium-ion battery is bad are checking its voltage, looking at its charge cycle count, or noticing any physical damage. If the voltage is less than 3.7 volts, the charge cycle count is much lower than predicted for your battery type, or the battery is swelling or leaking. It could signal that your battery has failed.

Signs of a bad lithium-ion battery

Swelling or leaking of the battery

A lithium-ion battery that is swelling or leaking is not performing correctly and should be replaced. When heated, the liquid electrolyte in lithium-ion batteries expands, causing the battery to swell. A leaking electrolyte indicates that the battery has failed and must be replaced. To avoid potential safety issues, replace your lithium-ion battery as soon as possible if you see any swelling or leaking.

Rapid loss of charge or shorter battery life

The most typical symptom is a quick loss of charge or a reduction in battery life. This could indicate that your gadget isn’t keeping a charge as well as it once did or that you need to recharge it more frequently than usual. Other indicators include the device turning on slowly, charging taking longer than expected, or the battery becoming unusually hot. If you’re experiencing any of these symptoms, it’s time to replace your lithium-ion battery.

Overheating or unusual warmth while charging

A battery should remain cool to ensure optimal performance and longevity. Overheating or unusual warmth while charging may indicate a faulty battery. It would help if you took this as a warning sign that something is wrong. Suppose your lithium-ion battery overheats or feels warm while charging. In that case, it’s best to discontinue use immediately and renew batteries if you have an extra one available.

Physical damage or deformations

Physical damage or deformations are a sure sign that your lithium-ion battery is bad. If you notice any bulging, swelling, or dents on the battery’s exterior, it’s time to replace it. Additionally, any visible signs of corrosion or rust on the battery’s terminals indicate a faulty cell and should be replaced as soon as possible. 

How to test a lithium-ion battery?

Testing a lithium-ion battery is a simple process that may be completed in a few steps. To begin, use a multimeter to measure the voltage of the battery. Next, connect your multimeter leads to both terminals of your lithium-ion battery to measure its resistance. Finally, you can test its capacity by draining it and then measuring its capacity using a charge cycle analyzer.

Using a multimeter to check the battery’s voltage

To begin, turn on the multimeter and set it to measure voltage. Connect the multimeter probes to the positive and negative terminals of the battery. The multimeter’s LED display will show the battery voltage at that moment. A wholly charged single cell should measure around 4.2V. In contrast, voltages as low as 3.3V may indicate that the battery needs to be recharged. If it’s greater than expected, it could tell that your battery has been overcharged and needs to be replaced.

Additionally, make sure to alter the parameters so that it can measure at least the maximum amount of volts the battery can generate. Once all these processes are accomplished, it is simple to ascertain the battery’s voltage and condition.

Measuring the battery’s internal resistance

Measuring the internal resistance can tell you how much energy the battery can deliver when needed, how much power it has left available, and whether or not it is functioning correctly. Knowing this information will help keep your device running smoothly and safely.

To test a lithium-ion battery’s internal resistance, you’ll need to use a multimeter, which measures electrical current flow through two wires connected to the battery’s terminals. Set your multimeter to measure OHMs and connect each wire to one of the terminals on the battery while taking care not to touch any exposed metal parts with your hands or tools. Once everything is connected correctly, take a reading of the Ohms displayed on your multimeter – that number will indicate your battery’s overall performance and condition.

Checking the battery’s capacity with a capacity tester

The first step in testing the capacity of a lithium-ion battery is to use a capacity tester. A capacity tester measures the amount of power stored inside the battery. It helps determine how much charge it holds compared to when it was brand new. The test involves connecting the capacity tester directly to the battery’s terminals and taking multiple readings from different discharge levels until it reaches zero or empty state voltage (ESV). This will allow you to accurately gauge its capacity and compare it with what should be expected for that battery.

Causes of a bad lithium-ion battery

There are four main causes for a bad lithium-ion battery: overcharging or over-discharging, physical damage or deformations, age and usage history, and extreme temperatures. 

Overcharging or over-discharging

Lithium-ion batteries are susceptible to overcharging and over-discharging, both of which can result in catastrophic damage. Overcharging happens when a battery is charged past its maximum capacity, resulting in decreased performance and probable battery damage. Over-discharging occurs when the battery’s power is depleted too quickly, resulting in reduced performance and perhaps irreparable harm.

Use a dependable charger for your lithium-ion battery; never let it charge overnight or for extended periods. Furthermore, you should avoid depleting the battery before recharging it since this might result in diminished performance or even irreversible damage.

Physical damage or deformations

Physical damage or deformations are among the most common causes of a bad lithium-ion battery. This can range from dents, cracks, and other external deformities to internal damage caused by overcharging or extreme temperatures. 

If you notice any physical damage to your lithium-ion battery, it must be replaced as soon as possible. Continuing to use a damaged battery can cause further harm to both the device and the battery itself. Additionally, any physical deformity can indicate that the battery is not functioning correctly and needs to be checked out. 

Age and usage history

A lithium-ion battery’s age and usage can both have an impact on its performance. The battery’s capacity to hold a charge gradually declines with age, which is why replacing your battery every few years is critical. Furthermore, you frequently use your device for intense gaming or video streaming activities. In that case, this can shorten the life of your battery.

Exposure to extreme temperatures

Extremely hot or cold temperatures can cause lithium-ion cells to overheat, leading to the formation of dendrites which can reduce battery life. Overheating in lithium-ion batteries is caused by an imbalance between the oxidation state of the active material and its reaction with electrolytes. As a result, elevated operating temperature, charge/discharge cycling, and high current load can all contribute to damage done by extreme temperatures. 

It is essential to store your lithium-ion battery correctly to help prevent damage from extreme heat or cold. Keep them at room temperature away from direct sunlight and heat sources like radiators or stoves.

What cause the lithium-ion battery swelling

What cause the lithium-ion battery swelling?

The lithium-ion battery has become an essential part of our lives, powering the devices that keep us connected and informed. Unfortunately, due to their complex design, lithium-ion batteries can sometimes suffer from swelling or bulging. This phenomenon can be hazardous, damaging the device and even causing a fire. This article will discuss what causes lithium-ion batteries to swell and how they can be prevented.

What cause the lithium-ion battery swelling

What Cause Lithium Battery Swelling?

Lithium-ion batteries swell due to several key factors: the age of the battery, exposure to high temperatures, overcharging, and defective or low quality. 

The age of the battery

The age of a lithium-ion battery can affect its performance, with the battery potentially swelling as it begins to degrade over time. Lithium-ion batteries are used in many standard devices, such as cell phones and computers, so it is essential to understand why this may happen.

Generally speaking, the cause for lithium-ion battery swelling is due to the accumulation of gas that builds up inside the battery over time. As the battery ages and cycles through charging and discharging, dendrites are formed, which can cause short circuits within the battery’s cells. This causes an increase in pressure within the cells resulting in them expanding or ‘swelling.’ This often results in poor performance or permanent damage to your device if left unresolved.

Exposure to high temperatures

Lithium-ion batteries can be prone to swelling if exposed to high temperatures. The phenomenon is known among engineers as a ‘thermal runaway.’ When a lithium-ion battery is exposed to heat above its rated limit of 60 degrees Celsius (140F), its electrolyte decomposes and releases gasses. This causes an increase in pressure and volume within the cell, which results in the tell-tale swelling that many of us have seen first-hand. Furthermore, as this process continues over time, it can lead to other thermal runaway events that result in short circuits or potentially even fire or explosions.


When a lithium-ion battery is charged beyond its capacity, it can cause the cell membranes to become unstable and increase pressure inside the cells leading to swelling. This can occur when using chargers with an improper voltage output or when a device is left plugged in too long. In addition to increasing size, overcharging can also decrease battery performance and possibly damage other components around the swollen area, like protective casing or circuit boards.

The Defective or low quality

Defective or low-quality lithium-ion batteries are prone to swelling because the battery cells have been poorly manufactured. This means they cannot contain and manage the energy produced when charging correctly. As a result, the cells will expand as more power is being put into them until they eventually rupture and swell up.

How to Prevent Lithium Battery Swelling?

Swelling or bloating lithium batteries is a serious issue as it can negatively affect the device, alter its performance, or even cause it to malfunction. Fortunately, there are several steps you can take to prevent this from happening.

Avoid excessive charge and discharge.

First and foremost, it is essential to charge them appropriately. Lithium batteries should always be plugged in if they have already reached their maximum capacity. Doing so will increase the battery’s internal pressure and lead to swelling. Additionally, users should avoid deep discharging a lithium-ion battery, Lithium batteries should be charged and discharged between 40-80%. The deep discharge will also strain it and result in swelling or other damage.

Use and preserve the battery at room temperature.

Second, keep your lithium battery at an optimal temperature. Temperature extremes can cause the battery to swell, so keep it between 0-45 degrees Celsius. And always store your device in a cool place away from direct sunlight or freezing temperatures.

Use high-quality chargers

Avoid using third-party chargers for your lithium battery as these may not be compatible with your device and could lead to overcharging or discharging the battery. Using only official chargers will help you maintain optimal lithium battery performance and reduce the risk of swelling.

Don’t leave your device plugged in.

You should avoid leaving your device plugged in for extended periods. Overcharging a lithium battery can cause it to swell and potentially damage your device’s internal components. To prevent this from happening, unplug your device once it’s fully charged and only plug it in again when you need to recharge. 

What Should I Do With Swollen Lithium-Ion Batteries?

There are several essential steps to take if you have a swollen lithium-ion battery. 

First and foremost, do not charge or use a device that has a swollen battery. Swelling indicates either a defect in the battery or an issue with how it is managed and charged. Using a malfunctioning battery could lead to further problems or even fire hazards. 

Secondly, remove the battery if possible and contact the manufacturer or retailer where you purchased your device. To determine what steps they recommend in terms of warranty coverage or replacement options for your swollen lithium-ion battery. 

Thirdly, safely dispose of your old lithium-ion battery by taking it to an authorized recycling center or another disposal facility for hazardous materials such as lithium batteries. Please do not put them into regular trash, as this poses environmental and safety risks for others who come into contact with it. 

Lastly, replace your lithium-ion battery with a new one from a reputable source if you intend to continue using the device powered by the swollen battery. Make sure its specifications match those of your original device’s power source so there won’t be any compatibility issues when using it again. 


The swelling of lithium-ion batteries is a serious concern that needs to be addressed. To avoid battery swelling, it is crucial to consider the safety guidelines associated with using and storing lithium-ion batteries. High temperatures, overcharging, and incorrect charging are all contributing factors that can cause battery swelling. Additionally, understanding the weak points of lithium-ion batteries and following manufacturers’ recommendations can help prevent battery swelling in the future.

This could lead to a dangerous situation where one battery ends up discharging too quickly or becomes over-charged due to an imbalance in current flow between them.

Matching Voltage

The voltages on each battery should also be equal so that they don’t draw more current from any one battery than another. Suppose a significant difference exists between two connected LiFepo4 cells’ voltage levels. In that case, this can cause an uneven charging or discharging cycle, which can put undue strain on the system and potentially cause damage or even fire-hazard conditions. Additionally, suppose two different LiFePo4 cells with varying voltage levels are connected. In that case, this can create an overcurrent situation and put additional stress on the components throughout your system.

Matching Age 

Finally, you should also ensure that all of your LiFepO4 cells are roughly the same age before connecting them in parallel. Batteries degrade over time due to usage cycles, so if two cells have been used extensively compared to other newer ones already part of your system setup, then they may not be able to keep up with demands placed upon them by their counterparts – leading again to potential danger situations caused by imbalances or even short-circuiting scenarios occurring due to incompatible cell chemistry.

Potential hazards and how to avoid them

When connecting LiFePO4 batteries in parallel, several safety considerations should be considered. LiFePO4 (Lithium Iron Phosphate)  batteries are commonly used in electric vehicles, power tools, and battery storage systems due to their high energy density, low cost, and long life. However, if these batteries are misconnected or without the appropriate safety measures, they can pose a significant risk of fire and explosion.

Potential hazards include sparks from reverse polarity connections and internal cell heating caused by mismatched cells with different voltages. In addition, when LiFePO4 batteries are connected in parallel, there is an increased risk of overcharging or short-circuiting due to the higher currents that flow through the system.

To ensure the safe operation of your LiFePO4 battery system, it is essential to take certain precautions:

1. Ensure that all batteries have similar capacities and voltages before connecting them in parallel. This will reduce the risks associated with mismatched cells, including current imbalances and heat buildup.

2. Make sure that all cables used for connection are appropriately rated for the type of application being undertaken so that they do not become overloaded or cause sparks due to excessive voltage drop.

3. Use high-quality connectors that offer good conductivity and prevent accidental disconnects. This will help avoid sudden drops in voltage which can damage the battery pack or cause undesired outcomes such as sparking and fire/explosion hazards.

4. Always double-check current ratings before connecting multiple battery packs since this may cause a rise in voltage above recommended levels leading to potential overloads and damage to other components of your system if left unchecked.

5. Finally, always ensure you install an appropriate fuse at each junction point between LiFePO4 batteries connected in parallel to protect against short circuits or other unintended electrical issues that could lead to severe injury or death if left unchecked.

By following these simple guidelines, it is possible to minimize any potential risks associated with running LiFePO4 batteries in parallel while still enjoying their benefits, such as improved capacity, cost savings, and longer life span compared with traditional lead acid battery solutions.

In conclusion

It is possible to connect LiFePO4 batteries in parallel. It is an efficient way to increase energy storage capacity and provide a backup in the event of an individual battery failure. But it is important to note that since LiFePO4 batteries are not identical, a balancing circuit must be installed to work correctly. Furthermore, when connecting the batteries, precautions should be taken to prevent any short circuits or other safety hazards.
