The difference between button batteries in 2025 and 2032

Is there a difference between 2032 and 2025 button cells?

The thickness is different and the amount of active material filled is also different, which means the capacity is different.

For numbers 2032 and 2025, the first two digits represent the diameter of the pile, and the last two digits represent the height of the pile (10 times smaller), in mm

< p> CR2032:< /p>< p> Lithium manganese dioxide battery is named according to IEC standards. Among them, C- is a chemical battery system with lithium metal as the negative electrode and manganese dioxide as the positive electrode. the battery is cylindrical. If it is square, F is replaced; 20 means the battery diameter is 20mm and 32 means the battery height is 3.2mm. Rated voltage is 3.0V, final voltage is 2.0. V, and the rated capacity ranges from 200 to 230 mAh.

CR2025 battery:

Lithium manganese dioxide battery is named according to IEC C standards- is a lithium metal chemical battery system. as negative electrode and manganese dioxide as positive electrode R- means the shape of the battery is cylindrical, if it is square, F will replace it, 20 means the diameter of this battery is 20mm, 25 means the thickness . of this battery is 2.5mm. The rated voltage is 3.0 V, the end point voltage (end point voltage) is 2.0 V, and the rated capacity ranges from 140 to 170 mAh.

With the requirements of the new In the industry, there are also specially improved batteries that will have very different capacities, mainly to improve their large current output capacity, such as those used in flashlights or RF products. The shape is button battery, button battery, this button battery is often used. on the CMOS batteries of the motherboardcomputer, other memory functions or power-off protection modules, electronic scales and calculations on appliances, electronic dictionaries and other products.

Button batteries 2032 and 2025 can be used interchangeably

Yes, but? the edges of 2025 are small and need something to pad.

Hello, the models of the two different specifications, different, generally cannot be used universally.

Yes, the thickness of 2025 is a little thinner than that of 2032.

Can the 2025 and 2032 button cells be used interchangeably?

As long as you can install them, they can be used interchangeably. The two batteries are simply different in thickness.

Typically, 2032. batteries are more used on computer motherboards.

2025 is more commonly used incar keys

Are button batteries universal in 2025 and 2016?

Button batteries cannot be charged that much because they are. little.

The battery charging process will cause heating and expansion. If the button cell battery is charged, it will be easily deformed and broken, and may even cause an explosion.

Is the 2032 button cell a lithium-ion battery?

Most of them are lithium batteries, as can be seen from the battery.Is there a label on the lithium battery?

If not not labeled rechargeable, do not charge it, as there is a risk of explosion.

2032 button cell four groups of 12 capacity

2032 lithium battery is a common specification of button cell. 2032 is a small 3V disposable lithium battery, which cannot be recharged in the BIOS power supply of the computer motherboard. , toys, watches When used on the Internet, the battery capacity is generally only 40mah. If four groups are connected in series, you can get 12V 40mah battery.

What is the difference. between CR2025 and CR2032 button batteries

As for the universality of CR2025 and CR2032 button batteries, the answer is no. Although both batteries are rated at 3V, the key lies in their size and capacity. CR2032 battery has a diameter of 20mm and a thickness of 32mm, and its rated capacity is generally between 200-230mAh, while the diameter of CR2025 is also 20mm, but its thickness is only 25 mm and its nominal capacity is between 140 and 170 mAh. This means that their battery holders are incompatible, as battery holders are often designed for a specific size of battery, including the structure in which they are held and positioned.

Button cell battery connectors, such as CR2032and CR2025, are usually soldered onto the circuit board to power the module clock. Due to the difference in size, replacing the battery with only one model may cause changes in the circuit board design and may even not work properly. In addition, the classification of lithium batteries also includes disposable lithium manganese batteries (C series, 3V), lithium fluorocarbon batteries and ML lithium manganese secondary batteries (ML series, 3V), but the points Common between these batteries are different from specific circumstances. CR2025 and CR2032 are different.

In summary, the battery holders and sizes of CR2025 and CR2032 do not match, so they cannot be used universally in practical applications. When choosing a coin cell battery, make sure it is compatible with the circuit board design, otherwise it may affect thenormal operation of the device.

The differences are as follows:

1. The sizes are different.

The numbers after CR represent the battery size, the first two numbers represent the diameter, and the last two numbers represent the thickness.

2032=20.0*3.2mm

2025=20.0*2.5mm

2.

2025 is thinner than 2032, so it has less capacity and a shorter lifespan. Both the CR2032 and CR2025 are 3V lithium manganese button cells. They have the same voltage and can be used interchangeably if necessary.

3. The discharge current is different.

CR2032 can support a maximum continuous current of 20 mA, while CR2025 can generally only support a discharge current of 10 mA. Therefore, when you choose a model, you need to match it according to the actual current your product uses.match.

Detailed information:

The model of button cell battery can be determined from the structure, voltage, size, etc. Standard classification can also be done for the classification of composite button cells. Practical lithium button batteries are generally labeled compositely in two aspects: structure and dimensions.

Button batteries can be divided into two types: rechargeable and non-rechargeable. Common rechargeable button batteries include 3.6V LIR series, 3V ML series and LV series. Non-rechargeable button cells include the 3V CR series, 1.5V LR series, and 1.55V SR series.

The button cell model consists of English letters and numbers. The first English letter indicates the chemical power source, and the four Arabic numeral suffix indicates the battery size. The first two numbers indicate the diameter andthe last. two numbers indicate the thickness.

Button batteries are small in size and are usually used as a backup power source for electronic products, such as computer motherboards, electronic watches, electronic dictionaries, electronic scales , calculators, etc., with diameters ranging from 4.8 mm. to 30 mm and thicknesses ranging from 1.0 mm to 7.7 mm.
