Comparison OF Common Button Battery Models: CR2025 VS CR2032

Simple Distinction Between The Two Button Batteries

First of all, we will find that the two models of button batteries have a feature, their diameter is 20 mm, which is easy to create misunderstandings, but when the two models of batteries together will find obvious characteristics, CR2032 than CR2025 will be thicker, CR2032 thickness is 3.2 mm, CR2032, the first model of the battery is more heavy. The CR2025 is 2.5 mm thick.

In fact, these characteristics are also related to the naming of button batteries, the first letter C stands for lithium manganese dioxide

• The letter R stands for circle, which means the battery is round
• The next four digits, and the first two are the diameter of the battery (usually measured in millimeters).
• The last two of the four digits represent the thickness of the battery model

A detailed Introduction To CR2025

First we need to understand that the CR2025 battery is a non-rechargeable battery. Its basic properties The voltage of the battery is 3V, the battery capacity is 170mAh, it is an extremely common button battery, relative to the common CR2032, its less battery capacity and thinner thickness, is the most obvious difference between the two

Although the battery capacity of CR2025 is small, if it is under normal conditions of use, there is no physical damage or exposure to normal temperature, it can be used for about 3-4 years in the car key, if it is used more frequently, such as equipment, the life may be greatly reduced

Similar to common button batteries, CR2025 batteries are mainly used in computer motherboards, automotive electronic keys, watches, calculators, and some toys

Details About CR2032

Also about the CR2032 button battery, its basic principle is the button battery can not be reused, the battery voltage is also 3V, the battery capacity is 240mAh, while the CR2032 battery can be installed connection sheet, with more compatibility, can be installed in more scenarios, such as optical scope, control panel and so on

The service life of CR2032 can be used normally for 10 years (provided that the battery power is still sufficient) under the control of no external conditions, and CR2032 can be used for 4-5 years when CR2025 is applied to the car key chain

In What Areas Can The Two Batteries Be Used To Replace Each Other

Under normal circumstances, the batteries of the two models can be replaced with each other, as long as the battery compartment can be installed and used normally, of course, this may also have a slight impact. The service life of CR2032 will be longer in applications. Because CR2032 has a higher electrical capacity

In summary, in most cases, as long as the battery can be stuffed into the battery bin for use, the two models of batteries can be replaced with each other. Of course, in many cases, the CR2025 battery is too small to fill the battery bin. At this time, if conditions permit, the gap of the battery bin can be filled by folding a piece of aluminum foil or other benign conductors. Then make sure that there are no errors in the positive and negative directions, in which case CR2025 can also be used in a specific CR2032 usage scenario

Analyze The Differences In Detail

In conclusion, there are many similarities between CR2032 and CR2025
The main similarities are that they have the same diameter, the same voltage, the same material, the same chemical composition, the same applications,
The main difference is only the thickness and battery capacity of these two, of course for some applications, thicker CR2032 or thinner CR2025 may not be compatible with each other
