Lithium-ion batteries have changed the way we use portable electronics. Now, they also power electric cars and renewable energy systems. These batteries can be recharged and are popular because they have high energy density, are lightweight, and last a long time.
Lithium-ion batteries are found in many devices, such as smartphones, laptops, electric cars, and solar power systems. Knowing how these batteries work, the different types available, and their uses can help us understand why they are essential and assist us in making smart choices about using them.
Lithium-ion batteries are rechargeable batteries that use lithium ions to hold and release energy. When the battery discharges, lithium ions move from the negative electrode (anode) to the positive electrode (cathode) through an external circuit, creating an electric current.
When charging the battery, the process goes in the opposite direction. An outside electrical source pushes the lithium ions back from the cathode to the anode. This back-and-forth movement of ions is what makes lithium-ion batteries rechargeable.
In short, the movement of lithium ions between the electrodes controls how the battery works. This action, caused by electrochemical reactions, allows the battery to change stored chemical energy into electrical energy, which powers devices.
The lithium-ion battery is built smartly to help lithium ions move easily. It has several important parts: the cathode (the positive electrode), the anode (the negative electrode), the electrolyte, the separator, and the current collectors.
The cathode is often made from lithium cobalt oxide, iron phosphate, or manganese oxide. It holds lithium ions when the battery charges. On the other hand, the anode is mainly made of graphite. It holds lithium ions when the battery discharges.
The electrolyte is a liquid or gel that helps lithium ions travel between the active materials of the electrodes. The separator is a special material that keeps the anode and cathode apart. It stops short circuits but lets ions flow. Finally, current collectors help electric flow in and out of the battery, which keeps the electrical circuit working.
During the use of a lithium-ion battery, like on your smartphone, lithium ions move from the anode to the cathode through the electrolyte. This movement makes an electrical current that powers your device. The discharge rate shows how quickly the battery is used up, while the state of charge tells you how much energy is left in the battery when operating at high voltage.
When you charge a lithium-ion battery, the process changes. Lithium ions move back from the cathode to the anode, which stores the electrical energy as chemical potential energy. The battery’s cycle life refers to how many times it can be charged and discharged before it loses too much capacity.
Lithium-ion battery technology has changed a lot. It now includes many different types of batteries, each with its own special qualities for different uses. Knowing these differences is important to choosing the right battery for your needs.
The most common types of lithium-ion batteries are:

Lithium-ion batteries have many advantages, but we must also consider their disadvantages. Knowing these limitations is important for making smart choices about using them and taking the right safety steps.
Some downsides are safety risks from overheating, the requirement for protective circuits, and their higher cost than other battery technologies.
While lithium-ion batteries are usually safe if used and handled properly, they can become dangerous if misused or in extreme cases. The electrolytes in these batteries can catch fire, and if they overheat, thermal runaway can occur, potentially causing a fire or explosion.
Lithium-ion batteries often have safety features like a battery protection circuit to lower these risks. This circuit helps stop overcharging, over-discharging, and too much current flow, making hazards less likely.
It’s also essential to follow the manufacturer’s guidelines on charging, storing, and disposing of the batteries. By sticking to these recommendations, you can keep lithium-ion batteries safe and working well for a long time.
Although the cost of lithium-ion batteries has decreased significantly over the years, they are still more expensive than other types, such as lead-acid or nickel-cadmium batteries. Their manufacturing is complex, and the raw materials used are pricey.
This cost can be a concern for big projects or places where price matters. However, considering their long service life, high energy density, and good performance, they seem more cost-effective.
Over time, their longer service life, lower need for maintenance, and better efficiency can balance out the higher initial cost, making them a good choice for many uses.
To understand how vital lithium-ion batteries are, we need to compare them with other types of batteries. This comparison helps us see each battery’s strengths and weaknesses, which can help us choose the best battery for our specific needs.
Each type of battery has its benefits. However, lithium-ion batteries usually stand out in many current uses. They have better energy density, a longer lifespan, and more robust performance than other battery technologies.
Although people often mix the terms “lithium-ion” and “lithium,” they are different. The main difference is in their anode material. Lithium-ion batteries use lithium ions, while lithium batteries use lithium metal, which is very reactive.
This reactivity allows lithium batteries to store more energy. However, it also creates safety risks. Lithium metal batteries can form dendrites, which may cause short circuits and dangerous situations.
In contrast, lithium-ion batteries use a graphite anode, making them safer and more stable. However, they have a slightly lower energy density than lithium metal batteries.
| Feature | Lithium Battery | Lithium-ion Battery |
| Type | Single-Use | Rechargable |
| Anode | Lithium metal | Graphite |
| Energy Density | Higher | Lower |
| Shelf Life | Longer | Shorter |
| Applications | Water meter, electricity meter | Consumer electronics |
Lead-acid batteries are an old and common type of technology. They are often used in car starters and backup power systems. However, they do not store as much energy as lithium-ion batteries and do not last as long.
This means that a lead-acid battery holds less energy for the same size and has to be replaced more often. Lead-acid batteries charge themselves faster, meaning they lose power over time, even when unused.
On top of that, lead-acid batteries are heavier and larger than lithium-ion batteries. This makes them less ideal for situations where you need something light and easy to carry. Still, lead-acid batteries can be a cheaper choice when weight and size are not as important.
| Feature | Lead-Acid Battery | Lithium-ion Battery |
| Cost | Lower | Higher |
| Energy Density | Lower | Higher |
| Lifespan | Shorter | Longer |
| Maintenance | Require | Free |
| Weight | Heavier | Lighter |
| Safety | Less prone to thermal runaway | More prone to thermal runaway if damaged or mishandled |
| Environmental Impact | Lead is toxic | Green |
When you look at lithium-ion batteries, you compare two types: lithium cobalt oxide and lithium iron phosphate batteries. Most lithium-ion batteries use lithium cobalt oxide for their cathode. In contrast, lithium iron phosphate (LiFePO4) batteries use a different material for the cathode, which brings its strengths.
For example, lithium iron phosphate batteries last much longer than their lithium cobalt oxide counterparts. This is great for uses where you often charge and discharge, like in electric vehicles and energy storage systems.
On the other hand, lithium iron phosphate batteries have a bit lower energy density than lithium polymer batteries. This means that, for the same size, they might hold less energy than lithium cobalt oxide batteries. Still, lithium iron phosphate batteries’ better safety, longer life, and stability make them an excellent choice for specific uses.
| Feature | Lithium-ion (Li-ion) | Scenarios with high-security requirements |
| Energy Density | Higher | Lower |
| Lifespan | Moderate | Longer |
| Cost | Generally lower | Generally higher |
| Safety | Good | Excellent |
| Applications | Scenarios with high security requirements | Scenes that require high energy density |
The lifespan of a Lithium-Ion battery is important for its value. It is not just one number. It depends on many things, like how you use it, how you charge it, and where you store it. Knowing these factors can help you make your battery last longer.
Usually, we measure a lithium-ion battery’s lifespan in charge cycles, not years. A charge cycle happens when the battery completely discharges and then recharges. This does not have to be from 0% to 100%. It just needs to add up to a full cycle.
Lithium battery cycle life is how often a battery can be charged and discharged. It usually keeps working until it holds about 80% of its original power, despite the potential for battery degradation. This cycle life is very important for rechargeable batteries, as it tells us how often we can use the battery again before it needs to be replaced.
Many things can affect the cycle life of a lithium battery. These include the type of battery, how you use it, and the temperatures it works in. For example, if you discharge it deeply, it may not last as long as when you only partially discharge it.
Extreme temperatures, whether hot or cold, can make the battery break down faster. This can make the cycle life shorter. Knowing these factors and taking steps to reduce their effect can help you use your lithium batteries longer.
Cycle life tells us how often a lithium battery can be charged and discharged. In contrast, life expectancy is how long the battery can still work and hold a charge. This is often measured in years and is related to how the battery ages.
Even when you don’t use lithium batteries, they still slowly break down. This happens much slower but can still affect their calendar life. Therefore, even if the batteries haven’t been charged many times, they can still age.
This shows why it is essential to properly store lithium batteries to help them last longer, even when not in use. Things like the temperature you store them at and how charged they are can significantly affect how fast they age and their overall life expectancy.
Many things can affect how long a lithium-ion battery lasts. Knowing these things can help you make it last longer and work better. One of the main things is temperature. Very hot or cold temperatures can make the battery age faster.
Hot temperatures can harm the battery parts beyond repair. Cold temperatures can lower the battery capacity and make it harder for electricity to flow. Another critical point is how the batteries are stored.
Keeping batteries at high temperatures or storing them for a long time when fully charged or empty can reduce their lifespan.

Alkaline batteries are a popular power source. They are easy to use and meant for one-time use, so you cannot recharge them. However, a few special alkaline batteries can be recharged a little. You can find these batteries in many household items and professional tools, which shows how important they are in our daily lives.
People like alkaline batteries for several reasons. They are very powerful, last a long time, and cost less. Compared to other primary batteries, like carbon-zinc, alkaline batteries provide more energy and last longer, making them a good choice for everyday use.
Alkaline batteries are a kind of primary battery. They work by using a chemical reaction to produce electricity. This process cannot be reversed. Once the materials inside are gone, these batteries can’t make power anymore. You will have to change them when that occurs.
The battery’s voltage is very important. A regular alkaline battery gives off 1.5 volts, which stays strong for most purposes. You can connect several cells to create higher voltages, like in 9-volt batteries.
Inside an alkaline battery, electrons move between two pieces called electrodes. The negative electrode is made of zinc, and the positive electrode uses manganese dioxide. A substance known as potassium hydroxide electrolyte helps the electrons move. This movement creates electric current that powers your devices.
Understanding how manganese dioxide works in alkaline batteries helps us learn how these batteries function and last longer. Alkaline batteries operate through a chemical reaction inside them. In these batteries, zinc powder serves as the negative electrode, and manganese dioxide acts as the positive electrode. They also contain an alkaline electrolyte, which is made of potassium hydroxide.
When you use a battery, a reduction reaction occurs at the zinc electrodes. This reaction creates voltage and turns zinc into zinc oxide at the anode. The overall reaction in the battery creates electricity. Knowing how these chemical processes work helps us better understand alkaline batteries and shows us how long they can last.
If you know about chemical reactions, here are some formulas. They explain why alkaline batteries can provide power:
(1): Zn(s)+2OH−(aq)⇌ZnO(s)+H2O(l)+2e–
(2): 2MnO2(s)+H2O(l)+2e−⇌Mn2O3(s)+2OH−(aq)
When you blend them, the complete reaction appears like this:
(3): Zn(s)+2MnO2(s)⇌ZnO(s)+Mn2O3(s)
The life of alkaline batteries varies based on several factors. A key factor is how fast the battery is used. High-power devices, like cameras or toys, drain alkaline batteries quickly. This is not the case with low-power devices, like remote controls, which use the batteries at a slower rate.
Temperature plays a big role in how long alkaline batteries last. Extreme hot or cold temperatures can change the chemical reactions inside the battery, impacting how well the battery works and how long it will hold a charge.
Storage conditions matter a lot. When you look at how long alkaline batteries last, several factors come into play. Temperature changes are important. How often you use them also matters. Plus, the place where you keep them is key too. All these things help to understand the lifespan of alkaline batteries.

A CR2032 battery is a non-rechargeable (primary) lithium coin or “button” cell battery that is 20mm in diameter x 3.2mm in thickness. The CR2032 battery has a voltage of 3 volts and a capacity of up to 240mAh, depending on manufacturer specifications. The CR2032 is the most commonly used lithium coin cell battery.
The LIR (lithium-ion rechargeable) coin cell, also known as a button cell, is the most miniature, least expensive lithium-ion battery format. Rated at 3.7V, LIR coin cell voltages may be up to three times higher than traditional lithium metal batteries like Cd-Ni or MH-Ni types. The LIR2032 has a nominal voltage of 3.6 to 3.7 volts when fully charged. The “2032″ ” refers to its standard size, with a diameter of 20mm and a height of 3.2mm, the same size as non-rechargeable CR2032 lithium coin cell batteries.
LIR2032 and CR2032 batteries are coin-cell batteries with the same physical size and shape (20mm in diameter and 3.2mm in height), making them compatible regarding form factor. However, they have significant differences in terms of chemistry, voltage, rechargeability, and usage:
The primary difference between LIR2032 and CR2032 batteries lies in their chemistry and rechargeability. LIR2032 batteries are rechargeable lithium-ion batteries, while CR2032 batteries are non-rechargeable primary lithium batteries. Using the appropriate battery type for your device is essential to ensure proper performance and safety.
The difference is as follows:
The numbers behind CR represent the battery size. The first two are in diameter, and the latter two indicate thickness.
2032 = 20.0*3.2mm
2025 = 20.0*2.5mm
2025 is thinner than 2032, so the capacity is less, and the service life is shorter. CR2032 and CR2025 are 3V lithium manganese butt batteries. The voltage of the two is the same.
CR2032 can withstand a maximum continuous current of 20mA. In contrast, CR2025 usually can only withstand 10mA discharge current, so when selecting the model, it is necessary to match according to the actual current of your product.
The button battery model can be classified based on a single standard, such as structure, voltage, and dimensions, and composite buttons can be classified. Practical button lithium batteries are generally marked by structure and shape size.
The button battery can be divided into two types: charging and non-filled. Standard charging butt batteries include the 3.6V LIR series and 3V ML series, and LV series. The non-charging button battery includes 3V CR series, 1.5V LR series, and 1.55V SR series.
The button battery model consists of English letters and numbers. The English letters in the front represent the nature of chemical power, and the four Arabic numerals of the suffix represent the battery size.
The buttons are small in shape and are generally used in the reserve power of electronic products, such as computer motherboards, electronic watches, electronic dictionaries, electronic scales, calculators, etc., with diameters ranging from 4.8mm to 30mm and 1.0mm to 7.7mm.
Lithium-ion batteries have changed the way we use portable electronics. Now, they also power electric cars and renewable energy systems. These batteries can be recharged and are popular because they have high energy density, are lightweight, and last a long time.
Lithium-ion batteries are found in many devices, such as smartphones, laptops, electric cars, and solar power systems. Knowing how these batteries work, the different types available, and their uses can help us understand why they are essential and assist us in making smart choices about using them.
Lithium-ion batteries are rechargeable batteries that use lithium ions to hold and release energy. When the battery discharges, lithium ions move from the negative electrode (anode) to the positive electrode (cathode) through an external circuit, creating an electric current.
When charging the battery, the process goes in the opposite direction. An outside electrical source pushes the lithium ions back from the cathode to the anode. This back-and-forth movement of ions is what makes lithium-ion batteries rechargeable.
In short, the movement of lithium ions between the electrodes controls how the battery works. This action, caused by electrochemical reactions, allows the battery to change stored chemical energy into electrical energy, which powers devices.
The lithium-ion battery is built smartly to help lithium ions move easily. It has several important parts: the cathode (the positive electrode), the anode (the negative electrode), the electrolyte, the separator, and the current collectors.
The cathode is often made from lithium cobalt oxide, iron phosphate, or manganese oxide. It holds lithium ions when the battery charges. On the other hand, the anode is mainly made of graphite. It holds lithium ions when the battery discharges.
The electrolyte is a liquid or gel that helps lithium ions travel between the active materials of the electrodes. The separator is a special material that keeps the anode and cathode apart. It stops short circuits but lets ions flow. Finally, current collectors help electric flow in and out of the battery, which keeps the electrical circuit working.
During the use of a lithium-ion battery, like on your smartphone, lithium ions move from the anode to the cathode through the electrolyte. This movement makes an electrical current that powers your device. The discharge rate shows how quickly the battery is used up, while the state of charge tells you how much energy is left in the battery when operating at high voltage.
When you charge a lithium-ion battery, the process changes. Lithium ions move back from the cathode to the anode, which stores the electrical energy as chemical potential energy. The battery’s cycle life refers to how many times it can be charged and discharged before it loses too much capacity.
Lithium-ion battery technology has changed a lot. It now includes many different types of batteries, each with its own special qualities for different uses. Knowing these differences is important to choosing the right battery for your needs.
The most common types of lithium-ion batteries are:

Lithium-ion batteries have many advantages, but we must also consider their disadvantages. Knowing these limitations is important for making smart choices about using them and taking the right safety steps.
Some downsides are safety risks from overheating, the requirement for protective circuits, and their higher cost than other battery technologies.
While lithium-ion batteries are usually safe if used and handled properly, they can become dangerous if misused or in extreme cases. The electrolytes in these batteries can catch fire, and if they overheat, thermal runaway can occur, potentially causing a fire or explosion.
Lithium-ion batteries often have safety features like a battery protection circuit to lower these risks. This circuit helps stop overcharging, over-discharging, and too much current flow, making hazards less likely.
It’s also essential to follow the manufacturer’s guidelines on charging, storing, and disposing of the batteries. By sticking to these recommendations, you can keep lithium-ion batteries safe and working well for a long time.
Although the cost of lithium-ion batteries has decreased significantly over the years, they are still more expensive than other types, such as lead-acid or nickel-cadmium batteries. Their manufacturing is complex, and the raw materials used are pricey.
This cost can be a concern for big projects or places where price matters. However, considering their long service life, high energy density, and good performance, they seem more cost-effective.
Over time, their longer service life, lower need for maintenance, and better efficiency can balance out the higher initial cost, making them a good choice for many uses.
To understand how vital lithium-ion batteries are, we need to compare them with other types of batteries. This comparison helps us see each battery’s strengths and weaknesses, which can help us choose the best battery for our specific needs.
Each type of battery has its benefits. However, lithium-ion batteries usually stand out in many current uses. They have better energy density, a longer lifespan, and more robust performance than other battery technologies.
Although people often mix the terms “lithium-ion” and “lithium,” they are different. The main difference is in their anode material. Lithium-ion batteries use lithium ions, while lithium batteries use lithium metal, which is very reactive.
This reactivity allows lithium batteries to store more energy. However, it also creates safety risks. Lithium metal batteries can form dendrites, which may cause short circuits and dangerous situations.
In contrast, lithium-ion batteries use a graphite anode, making them safer and more stable. However, they have a slightly lower energy density than lithium metal batteries.

| Cost | Lower | Higher |
| Energy Density | Lower | Higher |
| Lifespan | Shorter | Longer |
| Maintenance | Require | Free |
| Weight | Heavier | Lighter |
| Safety | Less prone to thermal runaway | More prone to thermal runaway if damaged or mishandled |
| Environmental Impact | Lead is toxic | Green |
When you look at lithium-ion batteries, you compare two types: lithium cobalt oxide and lithium iron phosphate batteries. Most lithium-ion batteries use lithium cobalt oxide for their cathode. In contrast, lithium iron phosphate (LiFePO4) batteries use a different material for the cathode, which brings its strengths.
For example, lithium iron phosphate batteries last much longer than their lithium cobalt oxide counterparts. This is great for uses where you often charge and discharge, like in electric vehicles and energy storage systems.
On the other hand, lithium iron phosphate batteries have a bit lower energy density than lithium polymer batteries. This means that, for the same size, they might hold less energy than lithium cobalt oxide batteries. Still, lithium iron phosphate batteries’ better safety, longer life, and stability make them an excellent choice for specific uses.

| Applications | Scenarios with high security requirements | Scenes that require high energy density |
The lifespan of a Lithium-Ion battery is important for its value. It is not just one number. It depends on many things, like how you use it, how you charge it, and where you store it. Knowing these factors can help you make your battery last longer.
Usually, we measure a lithium-ion battery’s lifespan in charge cycles, not years. A charge cycle happens when the battery completely discharges and then recharges. This does not have to be from 0% to 100%. It just needs to add up to a full cycle.
Lithium battery cycle life is how often a battery can be charged and discharged. It usually keeps working until it holds about 80% of its original power, despite the potential for battery degradation. This cycle life is very important for rechargeable batteries, as it tells us how often we can use the battery again before it needs to be replaced.
Many things can affect the cycle life of a lithium battery. These include the type of battery, how you use it, and the temperatures it works in. For example, if you discharge it deeply, it may not last as long as when you only partially discharge it.
Extreme temperatures, whether hot or cold, can make the battery break down faster. This can make the cycle life shorter. Knowing these factors and taking steps to reduce their effect can help you use your lithium batteries longer.
Cycle life tells us how often a lithium battery can be charged and discharged. In contrast, life expectancy is how long the battery can still work and hold a charge. This is often measured in years and is related to how the battery ages.
Even when you don’t use lithium batteries, they still slowly break down. This happens much slower but can still affect their calendar life. Therefore, even if the batteries haven’t been charged many times, they can still age.
This shows why it is essential to properly store lithium batteries to help them last longer, even when not in use. Things like the temperature you store them at and how charged they are can significantly affect how fast they age and their overall life expectancy.
Many things can affect how long a lithium-ion battery lasts. Knowing these things can help you make it last longer and work better. One of the main things is temperature. Very hot or cold temperatures can make the battery age faster.

Alkaline batteries are a popular power source. They are easy to use and meant for one-time use, so you cannot recharge them. However, a few special alkaline batteries can be recharged a little. You can find these batteries in many household items and professional tools, which shows how important they are in our daily lives.
People like alkaline batteries for several reasons. They are very powerful, last a long time, and cost less. Compared to other primary batteries, like carbon-zinc, alkaline batteries provide more energy and last longer, making them a good choice for everyday use.
Alkaline batteries are a kind of primary battery. They work by using a chemical reaction to produce electricity. This process cannot be reversed. Once the materials inside are gone, these batteries can’t make power anymore. You will have to change them when that occurs.
The battery’s voltage is very important. A regular alkaline battery gives off 1.5 volts, which stays strong for most purposes. You can connect several cells to create higher voltages, like in 9-volt batteries.
Inside an alkaline battery, electrons move between two pieces called electrodes. The negative electrode is made of zinc, and the positive electrode uses manganese dioxide. A substance known as potassium hydroxide electrolyte helps the electrons move. This movement creates electric current that powers your devices.
Understanding how manganese dioxide works in alkaline batteries helps us learn how these batteries function and last longer. Alkaline batteries operate through a chemical reaction inside them. In these batteries, zinc powder serves as the negative electrode, and manganese dioxide acts as the positive electrode. They also contain an alkaline electrolyte, which is made of potassium hydroxide.
When you use a battery, a reduction reaction occurs at the zinc electrodes. This reaction creates voltage and turns zinc into zinc oxide at the anode. The overall reaction in the battery creates electricity. Knowing how these chemical processes work helps us better understand alkaline batteries and shows us how long they can last.
If you know about chemical reactions, here are some formulas. They explain why alkaline batteries can provide power:
(1): Zn(s)+2OH−(aq)⇌ZnO(s)+H2O(l)+2e–
(2): 2MnO2(s)+H2O(l)+2e−⇌Mn2O3(s)+2OH−(aq)
When you blend them, the complete reaction appears like this:
(3): Zn(s)+2MnO2(s)⇌ZnO(s)+Mn2O3(s)
The life of alkaline batteries varies based on several factors. A key factor is how fast the battery is used. High-power devices, like cameras or toys, drain alkaline batteries quickly. This is not the case with low-power devices, like remote controls, which use the batteries at a slower rate.
Temperature plays a big role in how long alkaline batteries last. Extreme hot or cold temperatures can change the chemical reactions inside the battery, impacting how well the battery works and how long it will hold a charge.
Storage conditions matter a lot. When you look at how long alkaline batteries last, several factors come into play. Temperature changes are important. How often you use them also matters. Plus, the place where you keep them is key too. All these things help to understand the lifespan of alkaline batteries.

A CR2032 battery is a non-rechargeable (primary) lithium coin or “button” cell battery that is 20mm in diameter x 3.2mm in thickness. The CR2032 battery has a voltage of 3 volts and a capacity of up to 240mAh, depending on manufacturer specifications. The CR2032 is the most commonly used lithium coin cell battery.
The LIR (lithium-ion rechargeable) coin cell, also known as a button cell, is the most miniature, least expensive lithium-ion battery format. Rated at 3.7V, LIR coin cell voltages may be up to three times higher than traditional lithium metal batteries like Cd-Ni or MH-Ni types. The LIR2032 has a nominal voltage of 3.6 to 3.7 volts when fully charged. The “2032″ ” refers to its standard size, with a diameter of 20mm and a height of 3.2mm, the same size as non-rechargeable CR2032 lithium coin cell batteries.
LIR2032 and CR2032 batteries are coin-cell batteries with the same physical size and shape (20mm in diameter and 3.2mm in height), making them compatible regarding form factor. However, they have significant differences in terms of chemistry, voltage, rechargeability, and usage:
The primary difference between LIR2032 and CR2032 batteries lies in their chemistry and rechargeability. LIR2032 batteries are rechargeable lithium-ion batteries, while CR2032 batteries are non-rechargeable primary lithium batteries. Using the appropriate battery type for your device is essential to ensure proper performance and safety.
The difference is as follows:
The numbers behind CR represent the battery size. The first two are in diameter, and the latter two indicate thickness.
2032 = 20.0*3.2mm
2025 = 20.0*2.5mm
2025 is thinner than 2032, so the capacity is less, and the service life is shorter. CR2032 and CR2025 are 3V lithium manganese butt batteries. The voltage of the two is the same.
CR2032 can withstand a maximum continuous current of 20mA. In contrast, CR2025 usually can only withstand 10mA discharge current, so when selecting the model, it is necessary to match according to the actual current of your product.
The button battery model can be classified based on a single standard, such as structure, voltage, and dimensions, and composite buttons can be classified. Practical button lithium batteries are generally marked by structure and shape size.
The button battery can be divided into two types: charging and non-filled. Standard charging butt batteries include the 3.6V LIR series and 3V ML series, and LV series. The non-charging button battery includes 3V CR series, 1.5V LR series, and 1.55V SR series.
The button battery model consists of English letters and numbers. The English letters in the front represent the nature of chemical power, and the four Arabic numerals of the suffix represent the battery size.
The buttons are small in shape and are generally used in the reserve power of electronic products, such as computer motherboards, electronic watches, electronic dictionaries, electronic scales, calculators, etc., with diameters ranging from 4.8mm to 30mm and 1.0mm to 7.7mm.
